## Metrics
|
||
|
|
|
||
|
|
To expose metrics on a separate HTTP port, define it in the inventory with:
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
etcd_metrics_port: 2381
|
||
|
|
```
|
||
|
|
|
||
|
|
To create a service `etcd-metrics` and associated endpoints in the `kube-system` namespace,
|
||
|
|
define it's labels in the inventory with:
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
etcd_metrics_service_labels:
|
||
|
|
k8s-app: etcd
|
||
|
|
app.kubernetes.io/managed-by: Kubespray
|
||
|
|
app: kube-prometheus-stack-kube-etcd
|
||
|
|
release: prometheus-stack
|
||
|
|
```
|
||
|
|
|
||
|
|
The last two labels in the above example allows to scrape the metrics from the
|
||
|
|
[kube-prometheus-stack](https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack)
|
||
|
|
chart with the following Helm `values.yaml` :
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
kubeEtcd:
|
||
|
|
service:
|
||
|
|
enabled: false
|
||
|
|
```
