Argo CD

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.

Configure 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-1.27.3_windows_amd64.zip

After downloading the archive, extract its content 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.

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 <<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.
  • 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.

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.
