# Using Custom Prometheus
|
|
|
|
When using custom prometheus with Lens app, Lens expects certain things for prometheus rules and labels. Below is listed the changes required to see metrics properly.
|
|
|
|
## kube-prometheus
|
|
|
|
1. To see node metrics properly, please add
|
|
|
|
```
|
|
- action: replace
|
|
regex: (.*)
|
|
replacement: $1
|
|
sourceLabels:
|
|
- __meta_kubernetes_pod_node_name
|
|
targetLabel: kubernetes_node
|
|
```
|
|
|
|
relabeling to `node-exporter` servicemonitor crd (for example `kubectl edit -n monitoring servicemonitors node-exporter`).
|
|
|
|
2. To see cluster's pod usage on cluster overview properly, please add `metricsRelabeling` to `kubelet` service monitor (`kubectl edit -n monitoring servicemonitors kubelet`)
|
|
|
|
```
|
|
metricRelabelings:
|
|
- action: replace
|
|
sourceLabels:
|
|
- node
|
|
targetLabel: instance
|
|
```
|
|
|
|
## Helm chart
|
|
|
|
1. To see cpu metrics properly, please set value of `server.global.scrape_timeout` less than 1 minute, for example
|
|
|
|
```
|
|
helm upgrade --set server.global.scrape_interval=30s prometheus stable/prometheus
|
|
```
|
