Console based UI tool to monitor the status, performance and configuration of a Ceph cluster

cmon's Issues

Add a panel to show if backfill/recovery is active

An eyecatcher just to understand if there is a potential impact from recovery to client IO, would be worthwhile

switch to alertmanager for alerts

The 0.1 release goes direct to prometheus for the alerts, but these alerts could be silenced. By switching the source, the alerts table could show whether the alert is active/silenced too

Make the help screen scrollable!

Add an overlay panel (based on help) that shows ABOUT info

Use a '?' keypress to trigger an overlay that shows version and a compatibility table for each of the panels (since some releases don't have all the data available in Quincy)

support header tokens in prometheus and ceph api requests

OCP proxies the connections to endpoints, so raw http GETs will not work if you're trying to reach an OCP based ceph instance. This feature would update the config to provide tokens that would be used on the http calls.

support multiple clusters

In 0.1 release only a single ceph cluster is supported. This feature would change the way the config file is structured to support multiple clusters, allow one to be selected for display, and then use the list in a pulldown? in the UI to switch between clusters

indexerror

Noticed when the alert panel is active but there aren't any alerts listed, you can hit this traceback

Add a hosts breakdown panel

Use the metrics data to show the hosts in the cluster, and which daemons are running on those hosts. This could utilise the tree widget, where each host was a branch, and each daemon a leaf on the branch...presented in an overlay.
