Description Lubos Trilety 2017-10-09 09:59:30 UTC

Description of problem:
'Top 5' panels on 'Ceph Pools' dashboard don't show top 5 pools in the selected category. Instead they show first 5 pools ordered by chosen category.

Version-Release number of selected component (if applicable):
cephmetrics-grafana-plugins-0.1-372_g098fb9a.el7.centos.x86_64
cephmetrics-0.1-372_g098fb9a.el7.centos.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Create several pools, at least 5 (or have a rados gateway prepared and use it - 5 pools are created just for the gateway)
2. Create another pool(s)
3. Fill pools created in previous step with some data

Actual results:
Only pools created in first step are displayed in 'Top 5' panels. 

Expected results:
Top 5 pools in proper category should be displayed.

Additional info:

Comment 1 Paul Cuzner 2017-10-10 19:55:41 UTC

Queries needs to be updated to use a combination of limit for the top 5, with sortByMaxima calls
