Victoria Metrics Agent - collects metrics from various sources and stores them to VictoriaMetrics

Prerequisites

  • Install the follow packages: git, kubectl, helm, helm-docs. See this tutorial.

How to install

Access a Kubernetes cluster.

Setup chart repository (can be omitted for OCI repositories)

Add a chart helm repository with follow commands:

helm repo add vm https://victoriametrics.github.io/helm-charts/

helm repo update

List versions of vm/victoria-metrics-agent chart available to installation:

helm search repo vm/victoria-metrics-agent -l

Install victoria-metrics-agent chart

Export default values of victoria-metrics-agent chart to file values.yaml:

  • For HTTPS repository

    helm show values vm/victoria-metrics-agent > values.yaml
    
  • For OCI repository

    helm show values oci://ghcr.io/victoriametrics/helm-charts/victoria-metrics-agent > values.yaml
    

Change the values according to the need of the environment in values.yaml file.

Test the installation with command:

  • For HTTPS repository

    helm install vma vm/victoria-metrics-agent -f values.yaml -n NAMESPACE --debug --dry-run
    
  • For OCI repository

    helm install vma oci://ghcr.io/victoriametrics/helm-charts/victoria-metrics-agent -f values.yaml -n NAMESPACE --debug --dry-run
    

Install chart with command:

  • For HTTPS repository

    helm install vma vm/victoria-metrics-agent -f values.yaml -n NAMESPACE
    
  • For OCI repository

    helm install vma oci://ghcr.io/victoriametrics/helm-charts/victoria-metrics-agent -f values.yaml -n NAMESPACE
    

Get the pods lists by running this commands:

kubectl get pods -A | grep 'vma'

Get the application by running this command:

helm list -f vma -n NAMESPACE

See the history of versions of vma application with command.

helm history vma -n NAMESPACE

How to uninstall

Remove application with command.

helm uninstall vma -n NAMESPACE

Documentation of Helm Chart

Install helm-docs following the instructions on this tutorial.

Generate docs with helm-docs command.

cd charts/victoria-metrics-agent

helm-docs

The markdown generation is entirely go template driven. The tool parses metadata from charts and generates a number of sub-templates that can be referenced in a template file (by default README.md.gotmpl). If no template file is provided, the tool has a default internal template that will generate a reasonably formatted README.

Parameters

The following tables lists the configurable parameters of the chart and their default values.

Change the values according to the need of the environment in victoria-metrics-agent/values.yaml file.
