Description Shruti Sampat 2014-11-25 11:43:48 UTC 
Description of problem:
-------------------------

The thin-pool metadata utilization should be monitored in case of thinly-provisioned LVs. Currently the LV utilization and thin-pool data utilization is shown but not the metadata utilization.

Version-Release number of selected component (if applicable):
---------------------------------------------------------------
gluster-nagios-addons-0.1.13-1.el6rhs.x86_64

How reproducible:
-----------------
Always

Steps to Reproduce:
--------------------
1. Check the brick utilization service for a brick that uses a thinly provisioned LV.

Actual results:

Thin-pool metadata utilization not monitored.

Expected results:
------------------
Thin-pool metadata utilization should be monitored.

Comment 6 Shruti Sampat 2015-02-26 08:04:18 UTC 
The brick utilization service now shows individual graphs for space, inode, thinpool-data and thinpool-metadata utilization each. But each of the graphs show "Brick Usage" at the bottom of the graph. The same goes for each of the disk utilization graphs (these do not monitor bricks anymore). Moving back this bug to fix this.
Comment 8 Shruti Sampat 2015-03-04 17:23:32 UTC 
Verified as fixed in gluster-nagios-addons-0.1.16-1.el6rhs.x86_64 and nagios-server-addons-0.1.14-1.el6rhs.noarch

Brick utilization now monitors space and inode usage, as well as thin-pool space and metadata utilization.
