how to reuse grafana and prometheus

[jainpratik163]

we already have Prometheus/grafana/node-exporter/metric server already installed in our eks env.
so how can we use this k8s-monitoring helm chart?

Are there any grafana dashboards shared?

You can disable each dependent deployment using the enabled value of each subchart entry.

For example, to disable node exporter and kube-state-metrics from being deployed you can use these values.

Note that you may also need to set the labelMatchers to discover your existing deployments if they don't match the defaults:

metrics:
  kube-state-metrics:
    enabled: true
    labelMatchers:
      app.kubernetes.io/name: kube-state-metrics

  node-exporter:
    enabled: true
    labelMatchers:
      app.kubernetes.io/name: prometheus-node-exporter.*

kube-state-metrics:
  enabled: false

prometheus-node-exporter:
  enabled: false

For dashboards compatible with k8s-monitoring-helm chart, you can use Grafana Cloud Kubernetes Monitoring or the open-source kubernetes-mixin.

thanks for the update, one more doubt if we install this k8s-monitoring-helm chart will this also install all dashboard?

[skl]

@jainpratik163 the k8s-monitoring-helm chart does not include any dashboards, alerting or recording rules.

See here for more details on what is deployed:

It would be nice to have a flag "provision compatible dashboards to a grafana instance" (not trivial but definitely a nice step towards a complete solution for k8s).

Rule syncing will be tracked in this issue: #564.
I'm less interested in dashboard syncing, because this chart does not create, manage, or really know about Grafana at all. You can put dashboards in the Grafana Helm chart.

I'm going to close this, since @skl has answered the original question.
