Overview

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Telegraf is a plug-in driven server agent for collecting and sending metrics and events from databases, systems and IoT sensors.

To send your Prometheus-format Argo CD metrics to Logz.io, you need to add the inputs.prometheus and outputs.http plug-ins to your Telegraf configuration file.

Configuring Telegraf to send your metrics data to Logz.io

Set up Telegraf v1.17 or higher
For Windows:
wget https://dl.influxdata.com/telegraf/releases/telegraf-1.19.2_windows_amd64.zip

After downloading the archive, extract its contents into C:\Program Files\Logzio\telegraf\.

The configuration file is located at C:\Program Files\Logzio\telegraf\.

For MacOS:
brew install telegraf

The configuration file is located at /usr/local/etc/telegraf.conf.

For Linux:

Ubuntu & Debian

sudo apt-get update && sudo apt-get install telegraf

The configuration file is located at /etc/telegraf/telegraf.conf.

RedHat and CentOS

sudo yum install telegraf

The configuration file is located at /etc/telegraf/telegraf.conf.

SLES & openSUSE

# add go repository
zypper ar -f obs://devel:languages:go/ go
# install latest telegraf
zypper in telegraf

The configuration file is located at /etc/telegraf/telegraf.conf.

FreeBSD/PC-BSD

sudo pkg install telegraf

The configuration file is located at /etc/telegraf/telegraf.conf.

Expose Argo CD metrics

First, you need to expose Argo CD Prometheus-format metrics on your server.

Add the inputs.prometheus plug-in

Now you need to configure the input plug-in to enable Telegraf to scrape the Argo CD data from your hosts. To do this, add the following code to the configuration file:

[[inputs.prometheus]]
  ## An array of urls to scrape metrics from.
  urls = ["http://<<ARGOCD_HOST_URL>>:<<PORT>>/metrics"]
  • Replace <ARGOCD_HOST_URL>> with the URL of your Argo CD host.
  • Replace <<PORT>> with the port of your Argo CD host.
Add the outputs.http plug-in

After you create the configuration file, configure the output plug-in to enable Telegraf to send your data to Logz.io in Prometheus-format. To do this, add the following code to the configuration file:

[[outputs.http]]
  url = "https://<<LISTENER-HOST>>:8053"
  data_format = "prometheusremotewrite"
  [outputs.http.headers]
     Content-Type = "application/x-protobuf"
     Content-Encoding = "snappy"
     X-Prometheus-Remote-Write-Version = "0.1.0"
     Authorization = "Bearer <<PROMETHEUS-METRICS-SHIPPING-TOKEN>>"

Replace the placeholders to match your specifics. (They are indicated by the double angle brackets << >>):

  • Replace <<PROMETHEUS-METRICS-SHIPPING-TOKEN>> with a token for the Metrics account you want to ship to.
    Here’s how to look up your Metrics token.
  • Replace <<LISTENER-HOST>> with the Logz.io Listener URL for your region, configured to use port 8052 for http traffic, or port 8053 for https traffic. For example, listener.logz.io if your account is hosted on AWS US East, or listener-nl.logz.io if hosted on Azure West Europe.
Check Logz.io for your metrics

Log in to your Logz.io account and navigate to the current instructions page inside the Logz.io app. Install the pre-built dashboards 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.
