Re: Show and Tell: Grafana cluster dashboard

[Reed Dier]

I’ll +1 on InfluxDB rather than Prometheus, though I think having a version for each infrastructure path would be best.
I’m sure plenty here have existing InfluxDB infrastructure as their TSDB of choice, and moving to Prometheus would be less advantageous.

Conversely, I’m sure all of the Prometheus folks would be less inclined to move to InfluxDB for TSDB, so I think supporting both paths would be the best choice.

Looks very good. Is it anyhow possible to display the reason why a
cluster is in an error or warning state? Thinking about the output from
ceph -s if this could by shown in case there's a failure. I think this
will not be provided by default but wondering if it's possible to add.

That's the way we should go. Supporting both or in general as much as
possible (try to be generic)

Sorry for the late reply. We actually discussed this aspect during one
of the calls we had when discussing the Grafana dashboard integration
into the Ceph Manager Dashboard. Such kind of state information is
somewhat difficult to track and visualize using Prometheus/Grafana (or
any other TSDB, FWIW), as you can't store the actual reasons for why the
cluster is in HEALTH_WARN or HEALTH_ERR, for example.

We are therefore considering displaying this information in the form of
"native" widgets on the Manager Dashboard, and using the Grafana
dashboards for visualizing the other more suitable performance metrics.

Not yet.
Most daemon specific metric names (like ceph_osd_op[_r,_w,_rw) are derived 
directly from the respective perf counter names. The plugin exports all perf 
counters with PRIO_INTERESTING or higher (iirc).
An automatically created index would certainly be feasible.

Thanks, these metrics are in Luminous too. I seem unable to find some 
sort of register, to see which metrics mean what. Some are quite 
obvious, but others are a mystery. Does smth. like that exist somewhere?

Hi Jan,

first of all thanks for this dashboard.
A few comments:
-) 'vonage-status-panel' is needed, which isn't mentioned in the ReadMe
-) Using ceph 12.2.4 the mon metric for me is apparently called 
'ceph_mon_quorum_count' not 'ceph_mon_quorum_status'

And a question:
Is there a way to get the Cluster IOPS with prometheus metrics? I did 
this with collectd, but can't find a suitable metric from ceph-mgr.

Best regards,
Kurt

Show and Tell: Grafana cluster dashboard

[Jan Fajerski]

Hi all,
I'd like to request comments and feedback about a Grafana dashboard for Ceph 
cluster monitoring.

https://youtu.be/HJquM127wMY

https://github.com/ceph/ceph/pull/21850

The goal is to eventually have a set of default dashboards in the Ceph 
repository that offer decent monitoring for clusters of various (maybe even all) 
sizes and applications, or at least serve as a starting point for 
customizations.

Re: Show and Tell: Grafana cluster dashboard

[Marc Roos]

Looks nice 

- I rather have some dashboards with collectd/influxdb.
- Take into account bigger tv/screens eg 65" uhd. I am putting more 
stats on them than viewing them locally in a webbrowser.
- What is to be considered most important to have on your ceph 
dashboard? As a newbie I find it difficult to determine what is 
important to monitor.
- Maybe also some docs on what metrics you have taken and argumentation 
on how you used them (could be usefull if one wants to modify the 
dashboard for some other backend)
