In this blog i will cover how to monitor cstor-pools using Prometheus to pull metrics from maya-exporter sidecar of cstor-pool pods and Grafana to visualize the metrics.

It’s been almost a year since we have released cstor and we felt that there is a need of continuous monitoring tool to monitor cstor-pool container to get the details about various metrics such as health of cstor-pool container, no of reads/writes, no of io’s, rebuilding status, throughput, latency etc. So we introduced maya-exporter in 0.9.0 release as a sidecar of cstor-pool pod as well which collect metrics from cstor-pool container.

• cstor pool must be up and running
• PVC (*optional)

It’s optional since pool should be available before creating pvc’s

Steps to follow:

• Run kubectl create -f openebs-monitoring-pg.yaml
• Run kubectl get pods -o wide to verify and to get where Prometheus and Grafana instances are running.
• Run kubectl get nodes -o wide to get the…
