log4net

Before you begin, you'll need:

• log4net 2.0.8+.
• .NET Core SDK version 2.0+.
• .NET Framework version 4.6.1+.

Add the dependency

On Windows, navigate to your project folder, and run the following command:

Install-Package Logzio.DotNet.Log4net

On Mac or Linux, open Visual Studio, navigate to Project > Add NuGet Packages..., search and install Logzio.DotNet.Log4net.

Configure the appender in a configuration file

Use the sample configuration and edit it according to your needs. View log4net documentation for additional options.

<log4net>
    <appender name="LogzioAppender" type="Logzio.DotNet.Log4net.LogzioAppender, Logzio.DotNet.Log4net">
    <token><<LOG-SHIPPING-TOKEN>></token>
        <type>log4net</type>
        <listenerUrl>https://<<LISTENER-HOST>>:8071</listenerUrl>
        <bufferSize>100</bufferSize>
        <bufferTimeout>00:00:05</bufferTimeout>
        <retriesMaxAttempts>3</retriesMaxAttempts>
    <retriesInterval>00:00:02</retriesInterval>
    <gzip>true</gzip>
    <debug>false</debug>
    <jsonKeysCamelCase>false</jsonKeysCamelCase>
    <addTraceContext>false</addTraceContext>
    <useStaticHttpClient>false</useStaticHttpClient>

    </appender>

    <root>
        <level value="INFO" />
        <appender-ref ref="LogzioAppender" />
    </root>
</log4net>

To enable JSON format logging, add the following to your configuration file:

<parseJsonMessage>true</parseJsonMessage>

Next, reference the configuration file in your code as shown in the example here.

Run the code:

using System.IO;
using log4net;
using log4net.Config;
using System.Reflection;

namespace dotnet_log4net
{
    class Program
    {
        static void Main(string[] args)
        {
            var logger = LogManager.GetLogger(typeof(Program));
            var logRepository = LogManager.GetRepository(Assembly.GetEntryAssembly());

            // Replace "App.config" with the config file that holds your log4net configuration
            XmlConfigurator.Configure(logRepository, new FileInfo("App.config"));

            logger.Info("Now I don't blame him 'cause he run and hid");
            logger.Info("But the meanest thing he ever did");
            logger.Info("Before he left was he went and named me Sue");

            LogManager.Shutdown();
        }
    }
}

Configure the appender in the code

Use the sample configuration and edit it according to your needs. View log4net documentation for additional options.

var hierarchy = (Hierarchy)LogManager.GetRepository();
var logzioAppender = new LogzioAppender();
logzioAppender.AddToken("<<LOG-SHIPPING-TOKEN>>");
logzioAppender.AddListenerUrl("<<LISTENER-HOST>>");
logzioAppender.ActivateOptions();
hierarchy.Root.AddAppender(logzioAppender);
hierarchy.Root.Level = Level.All;
hierarchy.Configured = true;

Customize your code by adding the following:

Why?	What?
Enable proxy routing	logzioAppender.AddProxyAddress("http://your.proxy.com:port");
Enable sending logs in JSON format	logzioAppender.ParseJsonMessage(true);
Enable gzip compression	logzioAppender.AddGzip(true); , logzioAppender.ActivateOptions(); , logzioAppender.JsonKeysCamelCase(false); , logzioAppender.AddTraceContext(false); , logzioAppender.UseStaticHttpClient(false);

Parameters

Parameter	Description	Default/Required
token	Your Logz.io log shipping token securely directs the data to your Logz.io account. Replace <<LOG-SHIPPING-TOKEN>> with the token of the account you want to ship to.	Required
listenerUrl	Listener URL and port. Replace <<LISTENER-HOST>> with the host for your region. The required port depends whether HTTP or HTTPS is used: HTTP = 8070, HTTPS = 8071.	https://listener.logz.io:8071
type	The log type, shipped as type field. Used by Logz.io for consistent parsing. Can't contain spaces.	log4net
bufferSize	Maximum number of messages the logger will accumulate before sending them all as a bulk.	100
bufferTimeout	Maximum time to wait for more log lines, as hh:mm:ss.fff.	00:00:05
retriesMaxAttempts	Maximum number of attempts to connect to Logz.io.	3
retriesInterval	Time to wait between retries, as hh:mm:ss.fff.	00:00:02
gzip	To compress the data before shipping, true. Otherwise, false.	false
debug	To print debug messages to the console and trace log, true. Otherwise, false.	false
parseJsonMessage	To parse your message as JSON format, add this field and set it to true.	false
proxyAddress	Proxy address to route your logs through.	None
jsonKeysCamelCase	If you have custom fields keys that start with a capital letter and want to see the fields with a capital letter in Logz.io, set this field to true.	false
addTraceContext	To add trace context to each log, set this field to true.	false
useStaticHttpClient	To use the same static HTTP/s client for sending logs, set this field to true.	false

Custom fields

Add static keys and values to all log messages by including these custom fields under <appender>, as shown:

<appender name="LogzioAppender" type="Logzio.DotNet.Log4net.LogzioAppender, Logzio.DotNet.Log4net">
  <customField>
    <key>Environment</key>
    <value>Production</value>
  </customField>
  <customField>
    <key>Location</key>
    <value>New Jerseay B1</value>
  </customField>
</appender>

Extending the appender

To change or add fields to your logs, inherit the appender and override the ExtendValues method.

public class MyAppLogzioAppender : LogzioAppender
{
  protected override void ExtendValues(LoggingEvent loggingEvent, Dictionary<string, object> values)
  {
    values["logger"] = "MyPrefix." + values["logger"];
    values["myAppClientId"] = new ClientIdProvider().Get();
  }
}

Update your configuration to use the new appender name, such as MyAppLogzioAppender.

Add trace context

note

The Trace Context feature does not support .NET Standard 1.3.

To correlate logs with trace context in OpenTelemetry, set <addTraceContext>true</addTraceContext> in your configuration file or use logzioAppender.AddTraceContext(true); in your code. This adds span id and trace id to your logs. For example:

using log4net;
using log4net.Core;
using log4net.Repository.Hierarchy;
using Logzio.DotNet.Log4net;

namespace dotnet_log4net
{
    class Program
    {
        static void Main(string[] args)
        {
            var hierarchy = (Hierarchy)LogManager.GetRepository();
            var logger = LogManager.GetLogger(typeof(Program));
            var logzioAppender = new LogzioAppender();

            logzioAppender.AddToken("<<LOG-SHIPPING-TOKEN>>");
            logzioAppender.AddListenerUrl("https://<<LISTENER-HOST>>:8071");
            logzioAppender.AddTraceContext(true);
            logzioAppender.ActivateOptions();

            hierarchy.Root.AddAppender(logzioAppender);
            hierarchy.Configured = true;
            hierarchy.Root.Level = Level.All;

            logger.Info("Now I don't blame him 'cause he run and hid");
            logger.Info("But the meanest thing he ever did");
            logger.Info("Before he left was he went and named me Sue");

            LogManager.Shutdown();
        }
    }
}

Serverless platforms

For serverless functions, call the appender's flush method at the end to ensure logs are sent before execution finishes. Create a static appender in Startup.cs with UseStaticHttpClient set to true for consistent invocations.

For example:

Startup.cs

using Microsoft.Azure.Functions.Extensions.DependencyInjection;
using log4net;
using log4net.Repository.Hierarchy;
using Logzio.DotNet.Log4net;

[assembly: FunctionsStartup(typeof(LogzioLog4NetSampleApplication.Startup))]

namespace LogzioLog4NetSampleApplication
{
    public class Startup : FunctionsStartup
    {
        public override void Configure(IFunctionsHostBuilder builder)
        {
            var hierarchy = (Hierarchy)LogManager.GetRepository();
            var logzioAppender = new LogzioAppender();
            logzioAppender.AddToken("<<LOG-SHIPPING-TOKEN>>");
            logzioAppender.AddListenerUrl("https://<<LISTENER-HOST>>:8071");
            logzioAppender.ActivateOptions();
            logzioAppender.UseStaticHttpClient(true);
            hierarchy.Root.AddAppender(logzioAppender);
            hierarchy.Configured = true;
        }
    }
}

FunctionApp.cs

using System;
using Microsoft.Azure.WebJobs;
using Microsoft.Extensions.Logging;
using log4net;
using MicrosoftLogger = Microsoft.Extensions.Logging.ILogger;

namespace LogzioLog4NetSampleApplication
{
    public class TimerTriggerCSharpLog4Net
    {
        
        private static readonly ILog logger = LogManager.GetLogger(typeof(TimerTriggerCSharpLog4Net));

        [FunctionName("TimerTriggerCSharpLog4Net")]
        public void Run([TimerTrigger("*/30 * * * * *")]TimerInfo myTimer, MicrosoftLogger msLog)
        {
            msLog.LogInformation($"Log4Net C# Timer trigger function executed at: {DateTime.Now}");

            logger.Info("Now I don't blame him 'cause he run and hid");
            logger.Info("But the meanest thing he ever did");
            logger.Info("Before he left was he went and named me Sue");
            LogManager.Flush(5000);

            msLog.LogInformation($"Log4Net C# Timer trigger function finished at: {DateTime.Now}");
        }
    }
}

Code sample

using System;
using System.IO;
using Logzio.DotNet.NLog;
using NLog;
using NLog.Config;
using NLog.Fluent;

namespace LogzioNLogSampleApplication
{
  public class Program
  {
    static void Main(string[] args)
    {
      var logger = LogManager.GetCurrentClassLogger();

      logger.Info()
        .Message("If you'll be my bodyguard")
        .Property("iCanBe", "your long lost pal")
        .Property("iCanCallYou", "Betty, and Betty when you call me")
        .Property("youCanCallMe", "Al")
        .Write();

      LogManager.Shutdown(); 
    }
  }
}

Include context properties

Configure the target to include custom values when forwarding logs to Logz.io. For example:

<nlog>
  <variable name="site" value="New Zealand" />
  <variable name="rings" value="one" />
  <target name="logzio" type="Logzio" token="<<LOG-SHIPPING-TOKEN>>">
    <contextproperty name="site" layout="${site}" />
    <contextproperty name="rings" layout="${rings}" />
  </target>
</nlog>

Extending the appender

To change or add fields to your logs, inherit the appender and override the ExtendValues method.

[Target("MyAppLogzio")]
public class MyAppLogzioTarget : LogzioTarget
{
  protected override void ExtendValues(LogEventInfo logEvent, Dictionary<string, object> values)
  {
    values["logger"] = "MyPrefix." + values["logger"];
    values["myAppClientId"] = new ClientIdProvider().Get();
  }
}

Update your configuration to use the new appender name, such as MyAppLogzio.

JSON Layout

When using JsonLayout, set the attribute name to something other than 'message'. For example:

<layout type="JsonLayout" includeAllProperties="true">
 <attribute name="msg"  layout="${message}" encode="false"/>
</layout>

Add trace context

note

The Trace Context feature does not support .NET Standard 1.3.

To correlate logs with trace context in OpenTelemetry (auto or manual), set addTraceContext="true" in your configuration file or AddTraceContext = true in your code. This adds span id and trace id to your logs. For example:

var config = new LoggingConfiguration();

// Replace these parameters with your configuration
var logzioTarget = new LogzioTarget {
    Name = "Logzio",
    Token = "<<LOG-SHIPPING-TOKEN>>",
    LogzioType = "nlog",
    ListenerUrl = "<<LISTENER-HOST>>:8071",
    BufferSize = 100,
    BufferTimeout = TimeSpan.Parse("00:00:05"),
    RetriesMaxAttempts = 3,
    RetriesInterval = TimeSpan.Parse("00:00:02"),
    Debug = false,
    JsonKeysCamelCase = false,
    AddTraceContext = true,
    // ParseJsonMessage = true,
    // ProxyAddress = "http://your.proxy.com:port"
};

config.AddRule(LogLevel.Debug, LogLevel.Fatal, logzioTarget);
LogManager.Configuration = config;

Serverless platforms

For serverless functions, call the appender's flush method at the end to ensure logs are sent before execution finishes. Create a static appender in Startup.cs with UseStaticHttpClient flag set to true for consistent invocations.

        // Replace "App.config" with the config file that holds your log4net configuration
        XmlConfigurator.Configure(logRepository, new FileInfo("log4net.config"));

        logger.LogInformation("Hello");
        logger.LogInformation("Is it me you looking for?");

        LogManager.Shutdown();

        return Ok();
    }

.NET Core Desktop Application

    using System.IO;
    using System.Reflection;
    using log4net;
    using log4net.Config;
    using Microsoft.Extensions.Logging;

    namespace LoggerFactoryAppender
    {
        class Program
        {
            static void Main(string[] args)
            {
                ILoggerFactory loggerFactory = new LoggerFactory();
                loggerFactory.AddLog4Net();

                var logger = loggerFactory.CreateLogger<Program>();
                var logRepository = LogManager.GetRepository(Assembly.GetEntryAssembly());

                // Replace "App.config" with the config file that holds your log4net configuration
                XmlConfigurator.Configure(logRepository, new FileInfo("log4net.config"));

                logger.LogInformation("Hello");
                logger.LogInformation("Is it me you looking for?");

                LogManager.Shutdown();
            }
        }
    }

Custom fields

Add static keys and values to all log messages by including these custom fields under <appender>, as shown:

<appender name="LogzioAppender" type="Logzio.DotNet.Log4net.LogzioAppender, Logzio.DotNet.Log4net">
  <customField>
    <key>Environment</key>
    <value>Production</value>
  </customField>
  <customField>
    <key>Location</key>
    <value>New Jerseay B1</value>
  </customField>
</appender>

Extending the appender

To change or add fields to your logs, inherit the appender and override the ExtendValues method.

public class MyAppLogzioAppender : LogzioAppender
{
  protected override void ExtendValues(LoggingEvent loggingEvent, Dictionary<string, object> values)
  {
    values["logger"] = "MyPrefix." + values["logger"];
    values["myAppClientId"] = new ClientIdProvider().Get();
  }
}

Update your configuration to use the new appender name, such as MyAppLogzioAppender.

Add trace context

note

The Trace Context feature does not support .NET Standard 1.3.

To correlate logs with trace context in OpenTelemetry (auto or manual), set addTraceContext="true" in your configuration file or AddTraceContext = true in your code. This adds span id and trace id to your logs. For example:

var hierarchy = (Hierarchy)LogManager.GetRepository();
var logzioAppender = new LogzioAppender();
logzioAppender.AddToken("<<LOG-SHIPPING-TOKEN>>");
logzioAppender.AddListenerUrl("<<LISTENER-HOST>>");
logzioAppender.AddTraceContext(true);
logzioAppender.ActivateOptions();
hierarchy.Root.AddAppender(logzioAppender);
hierarchy.Root.Level = Level.All;
hierarchy.Configured = true;

Customize your code by adding the following:

Why?	What?
Enable proxy routing	logzioAppender.AddProxyAddress("http://your.proxy.com:port");
Enable sending logs in JSON format	logzioAppender.ParseJsonMessage(true);
Enable gzip compression	logzioAppender.AddGzip(true); , logzioAppender.ActivateOptions(); , logzioAppender.JsonKeysCamelCase(false);

Serverless platforms

For serverless functions, call the appender's flush method at the end to ensure logs are sent before execution finishes. Create a static appender in Startup.cs with UseStaticHttpClient set to true for consistent invocations.

            _logger.LogInformation($"LoggerFactory C# Timer trigger function finished at: {DateTime.Now}");

        }
    }
}

Serilog

note

This integration is based on Serilog.Sinks.Logz.Io repository. Refer to this repo for further usage and settings information.

Before you begin, you'll need:

• .NET Core SDK version 2.0+.
• .NET Framework version 4.6.1+.

Install the Logz.io Serilog sink

Install Serilog.Sinks.Logz.Io via Nuget or by running this command in the Package Manager Console:

PM> Install-Package Serilog.Sinks.Logz.Io

Configure the sink in a configuration file

Create an appsettings.json file and copy this configuration:

{
  "Serilog": {
    "MinimumLevel": "Warning",
    "WriteTo": [
      {
        "Name": "LogzIoDurableHttp",
        "Args": {
          "requestUri": "https://<<LISTENER-HOST>>:8071/?type=<<TYPE>>&token=<<LOG-SHIPPING-TOKEN>>"
        }
      }
    ]
  }
}

Replace <<LOG-SHIPPING-TOKEN>> with the token of the account you want to ship to.

Replace <<LISTENER-HOST>> with the host for your region. The required port depends whether HTTP or HTTPS is used: HTTP = 8070, HTTPS = 8071.

Replace <<TYPE>> with the log type to identify these logs in Logz.io.

Add the following code to use the configuration and create logs with Serilog.Settings.Configuration and Microsoft.Extensions.Configuration.Json packages:

using System.IO;
using System.Threading;
using Microsoft.Extensions.Configuration;
using Serilog;

namespace Example
{
    class Program
    {
        static void Main(string[] args)
        {
            var configuration = new ConfigurationBuilder()
                .SetBasePath(Directory.GetCurrentDirectory())
                .AddJsonFile("appsettings.json")
                .Build();

            var logger = new LoggerConfiguration()
                .ReadFrom.Configuration(configuration)
                .CreateLogger();

            logger.Information("Hello. Is it me you looking for?");
            Thread.Sleep(5000);     // gives the log enough time to be sent to Logz.io
        }
    }
}

Run the code:

using System.Threading;
using Serilog;
using Serilog.Sinks.Logz.Io;

namespace Example
{
    class Program
    {
        static void Main(string[] args)
        {
            ILogger logger = new LoggerConfiguration()
                .WriteTo.LogzIoDurableHttp(
                    "https://<<LISTENER-HOST>>:8071/?type=<<TYPE>>&token=<<LOG-SHIPPING-TOKEN>>",
                    logzioTextFormatterOptions: new LogzioTextFormatterOptions
                    {
                        BoostProperties = true,
                        LowercaseLevel = true,
                        IncludeMessageTemplate = true,
                        FieldNaming = LogzIoTextFormatterFieldNaming.CamelCase,
                        EventSizeLimitBytes = 261120,
                    })
                .MinimumLevel.Verbose()
                .CreateLogger();

            logger.Information("Hello. Is it me you looking for?");
            Thread.Sleep(5000);     // gives the log enough time to be sent to Logz.io
        }
    }
}

Serverless platforms

For serverless function, create a static appender in Startup.cs to ensure each invocation uses the same appender. For Serilog integration, use WriteTo.LogzIo() instead of WriteTo.LogzIoDurableHttp() for in-memory buffering, which is best for serverless functions.

Azure serverless function code sample

Startup.cs

using Microsoft.Azure.Functions.Extensions.DependencyInjection;
using Serilog;
using Serilog.Sinks.Logz.Io;

[assembly: FunctionsStartup(typeof(LogzioSerilogSampleApplication.Startup))]

namespace LogzioSerilogSampleApplication
{
    public class Startup : FunctionsStartup
    {
        public override void Configure(IFunctionsHostBuilder builder)
        {
            var logzioLogger = new LoggerConfiguration()
                .WriteTo.LogzIo("<<LOG-SHIPPING-TOKEN>>", "serilog", dataCenterSubDomain: "listener", useHttps: true)
                .CreateLogger();

            // Assign the logger to the static Log class
            Log.Logger = logzioLogger;
        }
    }
}

FunctionApp.cs

using System;
using Microsoft.Azure.WebJobs;
using Serilog;
using Microsoft.Extensions.Logging;
using MicrosoftLogger = Microsoft.Extensions.Logging.ILogger;
using Serilogger = Serilog.ILogger;
using System.Threading;

namespace LogzioSerilogSampleApplication
{
    public class TimerTriggerCSharpSeriLogzio
    {
        private static readonly Serilogger logzioLogger = Log.Logger;

        [FunctionName("TimerTriggerCSharpSeriLogzio")]
        public void Run([TimerTrigger("*/30 * * * * *")]TimerInfo myTimer, MicrosoftLogger msLog)
        {
            msLog.LogInformation($"Serilog C# Timer trigger function executed at: {DateTime.Now}");
              
            logzioLogger.Information("Hello. Is it me you're looking for?");

            msLog.LogInformation($"Serilog C# Timer trigger function finished at: {DateTime.Now}");
        }
    }
}

Replace <<LOG-SHIPPING-TOKEN>> with the token of the account you want to ship to.

Replace <<LISTENER-HOST>> with the host for your region. The required port depends whether HTTP or HTTPS is used: HTTP = 8070, HTTPS = 8071.

Replace <<TYPE>> with the log type to identify these logs in Logz.io.

OpenTelemetry

This integration uses the OpenTelemetry logging exporter to send logs to Logz.io via the OpenTelemetry Protocol (OTLP) listener.

Prerequisites

• .NET SDK 6+
• An ASP.NET Core application
• An active account with Logz.io

note

If you need an example aplication to test this integration, please refer to our .NET OpenTelemetry repository.

Configure the instrumentation

1. Add the packages

   dotnet add package OpenTelemetry.Extensions.Hosting
   dotnet add package OpenTelemetry.Instrumentation.AspNetCore
   dotnet add package OpenTelemetry.Exporter.OpenTelemetryProtocol

2. Setup the OpenTelemetry code in Program.cs, by adding the following lines:

   using OpenTelemetry;
   using OpenTelemetry.Logs;
   using OpenTelemetry.Resources;
   using OpenTelemetry.Exporter;   
   var builder = WebApplication.CreateBuilder(args);   
   const string serviceName = "YOUR-SERVICE-NAME";
   const string logzioEndpoint = "https://otlp-listener.logz.io/v1/logs";
   const string logzioToken = "<LOG-SHIPPING-TOKEN>";   
   builder.Logging.AddOpenTelemetry(options =>
   {
       options
           .SetResourceBuilder(
               ResourceBuilder.CreateDefault()
                   .AddService(serviceName))
           .AddOtlpExporter(otlpOptions =>
           {
               otlpOptions.Endpoint = new Uri(logzioEndpoint);
               otlpOptions.Headers = $"Authorization=Bearer {logzioToken}, user-agent=logzio-dotnet-logs-otlp";
               otlpOptions.Protocol = OtlpExportProtocol.HttpProtobuf;
           });
   });   
   var app = builder.Build();

   Replace YOUR-SERVICE-NAME with the required service name.

   Your Logz.io log shipping token directs the data securely to your Logz.io Log Management account. The default token is auto-populated in the examples when you're logged into the Logz.io app as an Admin. Manage your tokens.

   Update the listener.logz.io part in https://otlp-listener.logz.io/v1/logs with the URL for your hosting region.

3. Run your application.

Check Logz.io for your logs

Allow some time for data ingestion, then open Open Search Dashboards.

Encounter an issue? See our log shipping troubleshooting guide.

Metrics

Kubernetes

Helm manages packages of preconfigured Kubernetes resources using Charts. This integration allows you to collect and ship diagnostic metrics of your .NET application in Kubernetes to Logz.io, using dotnet-monitor and OpenTelemetry. logzio-dotnet-monitor runs as a sidecar in the same pod as the .NET application.

note

Project's GitHub repo

Sending metrics from nodes with taints

To ship metrics from nodes with taints, ensure the taint key values are included in your DaemonSet/Deployment configuration as follows:

tolerations:
- key: 
  operator: 
  value: 
  effect: 

To determine if a node uses taints as well as to display the taint keys, run:

kubectl get nodes -o json | jq ".items[]|{name:.metadata.name, taints:.spec.taints}"

note

You need to use Helm client with version v3.9.0 or above.

Standard configuration

1. Select the namespace

This integration deploys to the namespace specified in values.yaml. The default is logzio-dotnet-monitor.

To use a different namespace, run:

kubectl create namespace <<NAMESPACE>>

• Replace <<NAMESPACE>> with the name of your namespace.

2. Add logzio-helm repo

helm repo add logzio-helm https://logzio.github.io/logzio-helm
helm repo update

3. Run the Helm deployment code

helm install -n <<NAMESPACE>> \
--set secrets.logzioURL='<<LISTENER-HOST>>:8053' \
--set secrets.logzioToken='<<PROMETHEUS-METRICS-SHIPPING-TOKEN>>' \
--set-file dotnetAppContainers='<<DOTNET_APP_CONTAINERS_FILE>>' \
logzio-dotnet-monitor logzio-helm/logzio-dotnet-monitor 

• Replace <<NAMESPACE>> with the namespace you selected for this integration. The default value is default. Replace <<LISTENER-HOST>> with the host for your region. Replace <<LOG-SHIPPING-TOKEN>> with the token of the account you want to ship to.
• Replace <<DOTNET_APP_CONTAINERS_FILE>> with your .NET application containers file. Make sure your main .NET application container has the following volumeMount:

volumeMounts:
  - mountPath: /tmp
    name: diagnostics

4. Check Logz.io for your metrics

Allow some time for data ingestion, then open Logz.io. Search for your metrics in Logz.io by searching {job="dotnet-monitor-collector"}

Install the pre-built dashboard to enhance the observability of your metrics.

To view the metrics on the main dashboard, log in to your Logz.io Metrics account, and open the Logz.io Metrics tab.

Customizing Helm chart parameters

SDK

Send custom metrics from your .NET Core application using Logzio.App.Metrics, an open-source, cross-platform .NET library for recording metrics and forwarding them to Logz.io.

These instructions show you how to:

• Create a basic custom metrics export configuration with a hardcoded Logz.io exporter.
• Create a basic custom metrics export configuration with a Logz.io exporter defined by a configuration file.
• Add advanced settings to the basic custom metrics export configuration.

note

Project's GitHub repo

Send custom metrics with a hardcoded Logz.io exporter

Before you begin, you'll need:

• An application in .NET Core 3.1+.
• An active Logz.io account.

1. Install the App.Metrics.Logzio package

Run the following from the Package Manager Console:

Install-Package Logzio.App.Metrics

For manual installation, download the latest version from the NuGet Gallery.

2. Create MetricsBuilder

Copy and paste the following code into the function where you need to export metrics:

var metrics = new MetricsBuilder()
                .Report.ToLogzioHttp("<<LISTENER-HOST>>:<<PORT>>", "<<METRICS-SHIPPING-TOKEN>>")
                .Build();

Replace <<LISTENER-HOST>> with the host for your region. The required port depends whether HTTP or HTTPS is used: HTTP = 8070, HTTPS = 8071. For HTTPS communication, use port 8053. For HTTP communication, use port 8052.

Replace <<METRICS-SHIPPING-TOKEN>> with a token for the Metrics account you want to ship to. Look up your Metrics token.

3. Create Scheduler

To create the Scheduler, add the following code into the same function as the MetricsBuilder:

var scheduler = new AppMetricsTaskScheduler(
                TimeSpan.FromSeconds(15),
                async () => { await Task.WhenAll(metrics.ReportRunner.RunAllAsync()); });
scheduler.Start();

4. Add required metrics to your code

• Apdex (Application Performance Index) - Monitors end-user satisfaction.
• Counter - Tracks the number of times an event occurs.
• Gauge - Provides an instantaneous measurement of a value that can arbitrarily increase or decrease (e.g., CPU usage).
• Histogram - Measures the statistical distribution of a set of values.
• Meter - Measures the rate of event occurrences and the total count.
• Timer - Combines a histogram and meter to measure event duration, rate of occurrence, and duration statistics.

To use Logzio.App.Metrics, you must include at least one of the above metrics in your code.

For example, to add a counter metric, insert the following code block into the same function as the MetricsBuilder and Scheduler:

var counter = new CounterOptions {Name = "my_counter", Tags = new MetricTags("test", "my_test")};
metrics.Measure.Counter.Increment(counter);

In the example above, the metric has a name ("my_counter"), a tag key ("test") and a tag value ("my_test"): These parameters are used to query data from this metric in your Logz.io dashboard.

5. View your metrics

Run your application to start sending metrics to Logz.io.

Allow some time for data ingestion, then check your Metrics dashboard.

Filter metrics by labels

Once the metrics are in Logz.io, you can query them using labels. Each metric includes the following labels:

App Metrics parameter name	Description	Logz.io parameter name
Name	The name of the metric. Required for each metric.	Metric name if not stated otherwise
MeasurementUnit	The unit you use to measure. By default it is None.	unit
Context	The context which the metric belong to. By default it is Application.	context
Tags	Pairs of key and value of the metric. It is not required to have tags for a metric.	Tags keys

Some of the metrics have custom labels, as described below.

Send custom metrics with a Logz.io exporter defined by a config file

Before you begin, you'll need:

• An application in .NET Core 3.1+.
• An active Logz.io account.

1. Install the App.Metrics.Logzio package

Run the following from the Package Manager Console:

Install-Package Logzio.App.Metrics

For manual installation, download the latest version from the NuGet Gallery.

2. Create MetricsBuilder

Copy and paste the following code into the function where you need to export metrics:

var metrics = new MetricsBuilder()
                .Report.ToLogzioHttp("<<path_to_the_config_file>>")
                .Build();

Add the following to the configuration file:

<?xml version="1.0" encoding="utf-8"?>

<Configuration>
    <LogzioConnection>
        <Endpoint> <<LISTENER-HOST>> </Endpoint>
        <Token> <<METRICS-SHIPPING-TOKEN>> </Token>
    </LogzioConnection>
</Configuration>

Replace <<LISTENER-HOST>> with the host for your region. The required port depends whether HTTP or HTTPS is used: HTTP = 8070, HTTPS = 8071. For HTTPS communication, use port 8053. For HTTP communication, use port 8052.

Replace <<METRICS-SHIPPING-TOKEN>> with a token for the Metrics account you want to ship to. Look up your Metrics token.

3. Create Scheduler

Copy and paste the following code into the same function as the MetricsBuilder:

var scheduler = new AppMetricsTaskScheduler(
                TimeSpan.FromSeconds(15),
                async () => { await Task.WhenAll(metrics.ReportRunner.RunAllAsync()); });
scheduler.Start();

4. Add the required metrics to your code

• Apdex (Application Performance Index) - Monitors end-user satisfaction.
• Counter - Tracks the number of times an event occurs.
• Gauge - Provides an instantaneous measurement of a value that can arbitrarily increase or decrease (e.g., CPU usage).
• Histogram - Measures the statistical distribution of a set of values.
• Meter - Measures the rate of event occurrences and the total count.
• Timer - Combines a histogram and meter to measure event duration, rate of occurrence, and duration statistics.

To use Logzio.App.Metrics, you must include at least one of the above metrics in your code.

For example, to add a counter metric, insert the following code block into the same function as the MetricsBuilder and Scheduler:

var counter = new CounterOptions {Name = "my_counter", Tags = new MetricTags("test", "my_test")};
metrics.Measure.Counter.Increment(counter);

In the example above, the metric has a name ("my_counter"), a tag key ("test") and a tag value ("my_test"). These parameters are used to query data from this metric in your Logz.io dashboard.

5. View your metrics

Run your application to start sending metrics to Logz.io.

Allow some time for data ingestion, then check your Metrics dashboard.

Filter metrics by labels

Once the metrics are in Logz.io, you can query them using labels. Each metric includes the following labels:

App Metrics parameter name	Description	Logz.io parameter name
Name	The name of the metric. Required for each metric.	Metric name if not stated otherwise
MeasurementUnit	The unit you use to measure. By default it is None.	unit
Context	The context which the metric belong to. By default it is Application.	context
Tags	Pairs of key and value of the metric. It is not required to have tags for a metric.	Tags keys

Some of the metrics have custom labels as described below.

Export using ToLogzioHttp exporter

You can configure MetricsBuilder to use ToLogzioHttp exporter, which allows you to export metrics via HTTP using additional export settings. Add the following code block to define the MetricsBuilder:

var metrics = new MetricsBuilder()
                .Report.ToLogzioHttp(options =>
                {
                    options.Logzio.EndpointUri = new Uri("<<LISTENER-HOST>>:<<PORT>>");
                    options.Logzio.Token = "<<METRICS-SHIPPING-TOKEN>>";
                    options.FlushInterval = TimeSpan.FromSeconds(15);
                    options.Filter = new MetricsFilter().WhereType(MetricType.Counter);
                    options.HttpPolicy.BackoffPeriod = TimeSpan.FromSeconds(30);
                    options.HttpPolicy.FailuresBeforeBackoff = 5;
                    options.HttpPolicy.Timeout = TimeSpan.FromSeconds(10);
                })
                .Build();

• Replace <<LISTENER-HOST>> with the host for your region. The required port depends whether HTTP or HTTPS is used: HTTP = 8070, HTTPS = 8071. For HTTPS communication use port 8053. For HTTP communication use port 8052.
• Replace <<METRICS-SHIPPING-TOKEN>> with a token for the Metrics account you want to ship to. Look up your Metrics token.
• FlushInterval is the value in seconds defining delay between reporting metrics.
• Filteris used to filter metrics for this reporter.
• HttpPolicy.BackoffPeriod is the value in seconds defining the TimeSpan to back-off when metrics are failing to report to the metrics ingress endpoint.
• HttpPolicy.FailuresBeforeBackoff is the value defining the number of failures before backing-off when metrics are failing to report to the metrics ingress endpoint.
• HttpPolicy.Timeout is the value in seconds defining the HTTP timeout duration when attempting to report metrics to the metrics ingress endpoint.

.NET Core runtime metrics

The runtime metrics include additional parameters sent from your code, such as:

• Garbage collection frequencies, timings by generation/type, pause timings, and GC CPU consumption ratio.
• Heap size by generation.
• Bytes allocated by small/large object heap.
• JIT compilations and JIT CPU consumption ratio.
• Thread pool size, scheduling delays and reasons for growing/shrinking.
• Lock contention.

To enable the collection of these metrics with default settings, add the following code block after the MetricsBuilder:

// metrics is the MetricsBuilder
IDisposable collector = DotNetRuntimeStatsBuilder.Default(metrics).StartCollecting();

For custom settings, use the following code block after the MetricsBuilder:

IDisposable collector = DotNetRuntimeStatsBuilder
    .Customize()
    .WithContentionStats()
    .WithJitStats()
    .WithThreadPoolSchedulingStats()
    .WithThreadPoolStats()
    .WithGcStats()
    .StartCollecting(metrics);          // metrics is the MetricsBuilder

Data collected from these metrics is found in Logz.io, under the Contexts labels process and dotnet.

Get current snapshot

To enable the current snapshot preview of metrics in Logz.io format, add the following code block to the MetricsBuilder:

var metrics = new MetricsBuilder()
                .OutputMetrics.AsLogzioCompressedProtobuf()
                .Build();

var snapshot = metrics.Snapshot.Get();
            
using (var stream = new MemoryStream())
{
    await metrics.DefaultOutputMetricsFormatter.WriteAsync(stream, snapshot);

    // Your code here...
}

Traces

ASP.NET Core

Deploy this integration to enable automatic instrumentation of your ASP.NET Core application using OpenTelemetry.

Architecture overview

This integration includes:

• Installing the OpenTelemetry ASP.NET Core instrumentation packages on your application host
• Installing the OpenTelemetry collector with Logz.io exporter
• Running your ASP.NET Core application in conjunction with the OpenTelemetry instrumentation

On deployment, the ASP.NET Core instrumentation automatically captures spans from your application and forwards them to the collector, which exports the data to your Logz.io account.

Setup auto-instrumentation for your locally hosted ASP.NET Core application and send traces to Logz.io

Before you begin, you'll need:

• An ASP.NET Core application without instrumentation
• An active Logz.io account
• Port 4317 available on your host system
• A name defined for your tracing service. You will need it to identify the traces in Logz.io.

note

This integration uses OpenTelemetry Collector Contrib, not the OpenTelemetry Collector Core.

Download instrumentation packages

Run the following command from the application directory:

dotnet add package OpenTelemetry
dotnet add package OpenTelemetry.Exporter.OpenTelemetryProtocol
dotnet add package OpenTelemetry.Instrumentation.AspNetCore
dotnet add package OpenTelemetry.Extensions.Hosting

Enable instrumentation in the code

Add the following configuration to the beginning of the Startup.cs file:

using OpenTelemetry.Resources;
using OpenTelemetry.Trace;

Add the following configuration to the Startup class:

public void ConfigureServices(IServiceCollection services)
        {

            AppContext.SetSwitch("System.Net.Http.SocketsHttpHandler.Http2UnencryptedSupport", true);

            services.AddOpenTelemetryTracing((builder) => builder
                .AddAspNetCoreInstrumentation()
                .SetResourceBuilder(ResourceBuilder.CreateDefault().AddService("my-app"))
                .AddOtlpExporter(options =>
                {
                    options.Endpoint = new Uri("http://localhost:4317");
             
                })
            );
        }

Replace <<TRACING-SHIPPING-TOKEN>> with the token of the account you want to ship to.

Replace <<LOGZIO_ACCOUNT_REGION_CODE>> with the applicable region code.

Tail Sampling

tail_sampling defines which traces to sample after all spans in a request are completed. By default, it collects all traces with an error span, traces slower than 1000 ms, and 10% of all other traces.

Additional policy configurations can be added to the processor. For more details, refer to the OpenTelemetry Documentation.

The configurable parameters in the Logz.io default configuration are:

Parameter	Description	Default
threshold_ms	Threshold for the span latency - traces slower than this value will be included.	1000
sampling_percentage	Percentage of traces to sample using the probabilistic policy.	10

If you already have an OpenTelemetry installation, add the following parameters to the configuration file of your existing OpenTelemetry collector:

• Under the exporters list

  logzio/traces:
    account_token: <<TRACING-SHIPPING-TOKEN>>
    region: <<LOGZIO_ACCOUNT_REGION_CODE>>
    headers:
      user-agent: logzio-opentelemetry-traces

• Under the service list:

  extensions: [health_check, pprof, zpages]
  pipelines:
    traces:
      receivers: [otlp]
      processors: [tail_sampling, batch]
      exporters: [logzio/traces]

Give your traces some time to get from your system to ours, and then open Tracing.

Setup auto-instrumentation for your ASP.NET Core application using Docker and send traces to Logz.io

This integration enables you to auto-instrument your ASP.NET Core application and run a containerized OpenTelemetry collector to send your traces to Logz.io. If your application also runs in a Docker container, make sure that both the application and collector containers are on the same network.

Before you begin, you'll need:

• An ASP.NET Core application without instrumentation
• An active Logz.io account
• Port 4317 available on your host system
• A name defined for your tracing service

Download instrumentation packages

Run the following command from the application directory:

dotnet add package OpenTelemetry
dotnet add package OpenTelemetry.Exporter.OpenTelemetryProtocol
dotnet add package OpenTelemetry.Instrumentation.AspNetCore
dotnet add package OpenTelemetry.Extensions.Hosting

Enable instrumentation in the code

Add the following configuration to the beginning of the Startup.cs file:

using OpenTelemetry.Resources;
using OpenTelemetry.Trace;

Add the following configuration to the Startup class:

public void ConfigureServices(IServiceCollection services)
        {

            AppContext.SetSwitch("System.Net.Http.SocketsHttpHandler.Http2UnencryptedSupport", true);

            services.AddOpenTelemetryTracing((builder) => builder
                .AddAspNetCoreInstrumentation()
                .SetResourceBuilder(ResourceBuilder.CreateDefault().AddService("my-app"))
                .AddOtlpExporter(options =>
                {
                    options.Endpoint = new Uri("http://localhost:4317");
             
                })
            );
        }

Pull the Docker image for the OpenTelemetry collector

docker pull otel/opentelemetry-collector-contrib:0.111.0

Create a configuration file

Create a file config.yaml with the following content:

receivers:
  otlp:
    protocols:
      grpc:
        endpoint: "0.0.0.0:4317"
      http:
        endpoint: "0.0.0.0:4318"
  

exporters:
  logzio/traces:
    account_token: "<<TRACING-SHIPPING-TOKEN>>"
    region: "<<LOGZIO_ACCOUNT_REGION_CODE>>"
    headers:
      user-agent: logzio-opentelemetry-traces

  logging:

processors:
  batch:
  tail_sampling:
    policies:
      [
        {
          name: policy-errors,
          type: status_code,
          status_code: {status_codes: [ERROR]}
        },
        {
          name: policy-slow,
          type: latency,
          latency: {threshold_ms: 1000}
        }, 
        {
          name: policy-random-ok,
          type: probabilistic,
          probabilistic: {sampling_percentage: 10}
        }        
      ]

extensions:
  pprof:
    endpoint: :1777
  zpages:
    endpoint: :55679
  health_check:

service:
  extensions: [health_check, pprof, zpages]
  pipelines:
    traces:
      receivers: [otlp]
      processors: [tail_sampling, batch]
      exporters: [logging, logzio/traces]

Replace <<TRACING-SHIPPING-TOKEN>> with the token of the account you want to ship to.

Replace <<LOGZIO_ACCOUNT_REGION_CODE>> with the applicable region code.

Tail Sampling

tail_sampling defines which traces to sample after all spans in a request are completed. By default, it collects all traces with an error span, traces slower than 1000 ms, and 10% of all other traces.

Additional policy configurations can be added to the processor. For more details, refer to the OpenTelemetry Documentation.

The configurable parameters in the Logz.io default configuration are:

Parameter	Description	Default
threshold_ms	Threshold for the span latency - traces slower than this value will be included.	1000
sampling_percentage	Percentage of traces to sample using the probabilistic policy.	10

If you already have an OpenTelemetry installation, add the following parameters to the configuration file of your existing OpenTelemetry collector:

• Under the exporters list

  logzio/traces:
    account_token: <<TRACING-SHIPPING-TOKEN>>
    region: <<LOGZIO_ACCOUNT_REGION_CODE>>
    headers:
      user-agent: logzio-opentelemetry-traces

• Under the service list:

  extensions: [health_check, pprof, zpages]
  pipelines:
    traces:
      receivers: [otlp]
      processors: [tail_sampling, batch]
      exporters: [logzio/traces]

Replace <<TRACING-SHIPPING-TOKEN>> with the token of the account you want to ship to.

Replace <<LOGZIO_ACCOUNT_REGION_CODE>> with the applicable region code.

Here is an example configuration file:

receivers:  
  otlp:
    protocols:
      grpc:
      http:

exporters:
  logzio/traces:
    account_token: "<<TRACING-SHIPPING-TOKEN>>"
    region: "<<LOGZIO_ACCOUNT_REGION_CODE>>"
    headers:
      user-agent: logzio-opentelemetry-traces

processors:
  batch:
  tail_sampling:
    policies:
      [
        {
          name: policy-errors,
          type: status_code,
          status_code: {status_codes: [ERROR]}
        },
        {
          name: policy-slow,
          type: latency,
          latency: {threshold_ms: 1000}
        }, 
        {
          name: policy-random-ok,
          type: probabilistic,
          probabilistic: {sampling_percentage: 10}
        }        
      ]

  pprof:
    endpoint: :1777
  zpages:
    endpoint: :55679
  health_check:

service:
  extensions: [health_check, pprof, zpages]
  pipelines:
    traces:
      receivers: [otlp]
      processors: [tail_sampling, batch]
      exporters: [logzio/traces]

Replace <<TRACING-SHIPPING-TOKEN>> with the token of the account you want to ship to.

Replace <<LOGZIO_ACCOUNT_REGION_CODE>> with the applicable region code.

Run the container

Mount the config.yaml as volume to the docker run command and run it as follows.

Linux

docker run  \
--network host \
-v <PATH-TO>/config.yaml:/etc/otelcol-contrib/config.yaml \
otel/opentelemetry-collector-contrib:0.111.0

Replace <PATH-TO> to the path to the config.yaml file on your system.

Replace <<TRACING-SHIPPING-TOKEN>> with the token of the account you want to ship to.

Replace <<LOGZIO_ACCOUNT_REGION_CODE>> with the applicable region code.

Run the application

note

When running the OTEL collector in a Docker container, your application should run in separate containers on the same host network. Ensure all containers share the same network. Using Docker Compose ensures that all containers, including the OTEL collector, share the same network configuration automatically.

Run the application to generate traces.

Check Logz.io for your traces

Give your traces some time to get from your system to ours, and then open Tracing.
