Overview

logzio-otel-k8s-metrics allows you to ship metrics from your Kubernetes cluster to Logz.io with the OpenTelemetry collector.

This chart is a fork of the opentelemtry-collector Helm chart. It is also dependent on the kube-state-metrics, prometheus-node-exporter and prometheus-pushgatewaycharts, which are installed by default. To disable the dependency during installation, set kubeStateMetrics.enabled, nodeExporter.enabled or pushGateway.enabled to false.

Standard configuration

Add logzio-helm repo to your helm repo list
helm repo add logzio-helm https://logzio.github.io/logzio-helm
helm repo update

##### Deploy the Helm chart

To deploy the Helm chart, enter the relevant parameters for the placeholders and run the code.

Configure the parameters in the code

Replace the Logz-io <<PROMETHEUS-METRICS-SHIPPING-TOKEN>> with the token of the metrics account to which you want to send your data.

Replace <<LISTENER-HOST>> with your region’s listener host (for example, https://listener.logz.io:8053). For more information on finding your account’s region, see Account region.

Replace <<ENV-TAG>> with the name for the environment’s metrics, to easily identify the metrics for each environment.

Run the Helm deployment code
helm install  \
--set secrets.MetricsToken=<<PROMETHEUS-METRICS-SHIPPING-TOKEN>> \
--set secrets.ListenerHost=<<LISTENER-HOST>> \
--set secrets.p8s_logzio_name=<<ENV-TAG>> \
logzio-otel-k8s-metrics logzio-helm/logzio-otel-k8s-metrics
Check Logz.io for your metrics

Give your data some time to get from your system to ours, then log in to your Logz.io Metrics account, and open the Logz.io Metrics tab.

Customizing Helm chart parameters

Configure customization options

You can use the following options to update the Helm chart parameters:

  • Specify parameters using the --set key=value[,key=value] argument to helm install

  • Edit the values.yaml

  • Overide default values with your own my_values.yaml and apply it in the helm install command.

Example:
helm install logzio-otel-k8s-metrics logzio-helm/logzio-otel-k8s-metrics -f my_values.yaml 
Customize the metrics collected by the Helm chart

The default configuration uses the Prometheus receiver with the following scrape jobs:

  • Cadvisor: Scrapes container metrics
  • Kubernetes service endpoints: These jobs scrape metrics from the node exporters, from Kube state metrics, from any other service for which the prometheus.io/scrape: true annotaion is set, and from services that expose Prometheus metrics at the /metrics endpoint.

To customize your configuration, edit the config section in the values.yaml file.

Uninstalling the Chart

The uninstall command is used to remove all the Kubernetes components associated with the chart and to delete the release.

To uninstall the logzio-otel-k8s-metrics deployment, use the following command:

helm uninstall logzio-otel-k8s-metrics
