Description of problem: Host Utilization is NOT showing the charts for ALL the mounted disk partitions. To be more specific, the graphs for last 2 disk partitions are missing for all the hosts.


Version-Release number of selected component (if applicable):
rhsc-3.0.0-0.12.el6rhs.noarch
rhsc-monitoring-uiplugin-0.1.1-1.el6rhs.noarch

How reproducible: Always

My test setup is a RHSC + Nagios Setup with 4 RHS 3.0 nodes in a cluster called "DocCluster". Look for more details under Additional info.

Steps to Reproduce:

1. Login to RHSC
2. From the 'Tree' mode, Select any Host and click on the "Trends" tab and see the graphs


Actual results: The trends tab is showing the utilization graphs for all the physical entities like CPU, Memory, Swap, Network-Interfaces and Disks. But out of 4 mounted disk partitions (/rhs/brick1, /rhs/brick2, /rhs/brick3 and /rhs/brick4), the last two are NOT shown (/rhs/brick3 and /rhs/brick4) at all. This is the case with all the 4 nodes in the cluster.

If that is the case, I believe that last 2 mounted disk in a host will NOT be shown at all. For ex: If there are 8 mounted disks, only 6 will be shown in Trends. Is that right?

Expected results: The trends tab should show the utilization graphs for all the physical entities like CPU, Memory, Swap, Network-Interfaces and ALL mounted disk partitions.


Additional info: Screenshots attached. Some additional details about the test setup is given below for your reference:
