## Liveness
|
|
|
|
CSI deploys a sidecar container that is responsible for collecting metrics.
|
|
|
|
Liveness metrics are intended to be collected by prometheus but can be accessed
|
|
through a GET request to a specific pod ip.
|
|
|
|
for example
|
|
`curl -X get http://[pod ip]:[liveness-port][liveness-path] 2>/dev/null | grep csi`
|
|
|
|
the expected output should be
|
|
|
|
```bash
|
|
curl -X GET http://10.109.65.142:8080/metrics 2>/dev/null | grep csi
|
|
# HELP csi_liveness Liveness Probe
|
|
# TYPE csi_liveness gauge
|
|
csi_liveness 1
|
|
```
|
|
|
|
Prometheus can be deployed through the prometheus operator described [here](https://coreos.com/operators/prometheus/docs/latest/user-guides/getting-started.html).
|
|
The [service-monitor](../deploy/service-monitor.yaml) will tell prometheus how
|
|
to pull metrics out of CSI.
|
|
|
|
Each CSI pod has a service to expose the endpoint to prometheus. By default, rbd
|
|
pods run on port 8080 and cephfs 8081.
|
|
These can be changed if desired or if multiple ceph clusters are deployed more
|
|
ports will be used for additional CSI pods.
|
|
|
|
Note: You may need to open the ports used in your firewall depending on how your
|
|
cluster has set up.
