pcuzner/cmon repository overview

cmon is a light-weight monitoring tool for Ceph that runs in your console window. It exploits the metrics and state information that Ceph already provides to Prometheus, so all it needs is access to the http endpoints of the mgr/prometheus module...no complex client code and no changes to Ceph needed! In addition, cmon can also integrate with Prometheus to show active alerts and performance data (last 15 mins) to give you a more holistic view of your Ceph cluster's health, configuration and performance.

The github project can be found here : https://github.com/pcuzner/cmon⁠

Once you have the container, define an alias to create a new command like this;

alias cmon="podman run --interactive --tty --net=host -e TERM -e CEPH_URL=http://192.168.122.92:9283/metrics -e PROMETHEUS_URL=http://192.168.122.92:9095 --entrypoint='/cmon.py' docker.io/pcuzner/cmon:latest"

Just make CEPH_URL and PROMETHEUS_URL match the IPs or names within you environment, and you should be good to go.
