Document URL: https://access.redhat.com/documentation/en-US/Red_Hat_Storage/3.1/html-single/Administration_Guide/index.html#chap-Monitoring_Red_Hat_Storage Additional information: With this plug-in, users would be notified when self-heal is in progress.
The existing configuration "Volume Self Heal" has been changed to 2 services: - Volume Heal info UNKNOWN - if glusterd is not running or another transaction in progress (same as existing) WARNING - if command execution fails (same as existing) WARNING - if there are entries present that needs to be healed. The entry count displayed is across all bricks of volume, and may contain duplicates. The plugin also plots a trending graph that displays the unsynced entry count over time - Volume Split-brain status UNKNOWN - if glusterd is not running or another transaction in progress (same as existing) WARNING - if command execution fails (same as existing) CRITICAL - if entries found in split brain state. OK and NOT APPLICABLE states are same as before. I'm a little confused as to how the document already captures the 2 plugins - as this is a new change :) Regarding upgrades - Nagios server could be updated by itself, though typically the packages are shipped as part of RHGS/RHGS-C erratas.
The Installation guide looks fine. Had a few comments in Admin guide: Table 18.1 ----------- 1. Volume Self-Heal Info (available in Red Hat Gluster Storage version 3.1.3 and later) NOTAPPLICABLE Volume is not of replicate type. Displayed when there are no replicate volumes and therefore no need to self-heal. That is incorrect. There is no NOT APPLICABLE state that gets shown for this service. If a (distribute) replicate volume is created, then this service gets shown. And if a volume gets created for which healing is not valid, then this service does not get shown itself in the UI. So, please remove NOT APPLICABLE state. 2. Volume Split-Brain Status (available in Red Hat Gluster Storage version 3.1.0 and later) It is mentioned in Sahina's reply (comment 11), that Split brain status is only from 3.1.1 to 3.1.3 (and NOT in 3.1.0) Could you please align the cells of the table correctly for volume split brain status. Unable to make out the content correctly.
Moving this bug back to address the above issues.
Thanks Laura. Read through the above link, and the changes look good. Moving this BZ to verified in 3.1.3.
