Improve Dashboard: Ceph - Cluster

[Marc-Assmann]

• removed OSD Utilization panel for performance reason
• fix template variable selection to reflect dependencies
• consistently apply template variable filtering
  {cluster='$cluster',instance='$instance',job='ceph-exporter'} to: Pools,
  Average PGs per OSD, Average OSD Apply Latency, Average OSD Commit
  Latency, Objects in the Cluster, PGs, Stuck PGs, Recovery, Bytes, Keys,
  Objects
• Show header of "Recovery" row
• Dont display interpolated graphs on null values so that missing values
  in outage situations are visible
• Graph style: fill=0, line=1, point=1; stacked graph style: fill=1
• IOPs not stacked
• Throughput not stacked
• Capacity min y = 0 to make usage level obvious

Hi Marc, thanks a lot for your various enhancement requests for the Grafana dashboards - much appreciated! Would it be possible for you to attach some sample screen shots of the new widgets to your PRs? That makes it somewhat easier to review your suggested changes. Thanks!

See here a screenshot of the modified dashboard.
The title "Ceph - Cluster Copy" is changed to "Ceph - Cluster" in the dashboard json.

This new file is malformed. If you export the dashboard via Grafana as JSON file you can't simply replace it with the file in this repository. You need to modify it manually instead:

Modify the exported JSON file first:

1. Remove the __inputs object
2. Replace all occurances of ${DS_PROMETHEUS}: s/${DS_PROMETHEUS}/Prometheus/

Now insert the Grafana export into the GIT file:

{
    "overwrite": true,
    "dashboard": {
<-- INSERT HERE THE CODE FROM THE GRAFANA JSON EXPORT FILE -->
    }
}
