[Gluster-users] Gluster & Nagios False Alerts

[Mathieu Chateau]

Hello,

I am monitoring with nagios (Centreon to be exact), but not yet with script
provided by gluster dev.

I currently monitor through nrpe:

   - Gluster brick:
      - Disk space
      - glusterd daemon (present and #)
      - glusterfs daemon (present and #)
      - glusterfsd daemon (present and #)
   - Gluster client:
      - checking if all mount points are present using this script
      <https://github.com/echocat/nagios-plugin-check_mountpoints>


Monitoring do same things all the time. If it's reporting issue, but
resolving quick, you may have a repeating short issue.
Best shot in this case is to manually execute nagios script inside a loop,
like every 10s, to cach it by yourself.
If you wait for nagios alert to log on and try, short issue may already be
gone.


Cordialement,
