Description Lubos Trilety 2017-09-26 15:57:39 UTC

Description of problem:
'Ceph - At A Glance' Capacity panel doesn't show any units. The panel shows only percentage of usage. From that it's not clear how much space is used/left.

Version-Release number of selected component (if applicable):
cephmetrics-1.0-1.el7cp.x86_64
cephmetrics-grafana-plugins-1.0-1.el7cp.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Install cephmetrics
2. Look at Capacity panel on 'Ceph - At A Glance' dashboard
3.

Actual results:
Only percentage of usage is displayed

Expected results:
Hover on chart shows used size the same as 'Placement Group Status' panel chart do. There will be also information about total size.

Additional info:

Comment 1 Zack Cerza 2017-10-04 21:37:37 UTC

I don't think Grafana's singlestat panel supports this. The 'Placement Group Status' panel is a pie chart.

Comment 2 Paul Cuzner 2017-10-04 23:38:15 UTC

+1 The singlestat panel does not provide this feature. 

What we could do is link from the capacity gauge to the cluster dashboard that shows the bytes available used etc?

Comment 6 Lubos Trilety 2017-10-25 11:13:15 UTC

Tested with:
cephmetrics-1.0-6.el7cp.x86_64

The 'Ceph - At A Glance' Capacity panel is linked to Cluster Capacity panel. All other links go to some dashboard not panel, should not this one similarly goes to the 'Ceph Cluster' dashboard instead?

Comment 7 Paul Cuzner 2017-10-27 07:55:37 UTC

It does go to the dashboard, but auto zooms into the specific panel. You click on capacity and you get the capacity chart, press ESC and you see the dashboard.

Not sure what the problem is

Comment 8 Federico Lucifredi 2017-11-03 15:08:16 UTC

I am to keep current setup.

Comment 9 Lubos Trilety 2017-11-06 07:11:28 UTC

Tested with:
cephmetrics-1.0-7.el7cp.x86_64

With comment 8 in mind it works properly.
