Troubleshooting Elasticsearch cluster non nominal Nagios status¶
Why do that¶
Nagios reports a Yellow or Red status on an Elasticsearch cluster
What to do¶
Use the PunchPlatform Admin GUI :
: - To know the concerned ES cluster(s) - To know if it means:
1 2 3 4 5 6 7 8 9 | > - Under-replication (Yellow status of « online cluster »,
> and some of the indexes within)
> - Some Data unavailability (RED status of « online cluster »
> provided by elasticsearch). The indexes are listed in the
> HMI, and at least some are in RED health.
> - Cluster unavailability (RED status of «online cluster »
> but service says « unable to determine cluster status »
> - Housekeeping problem (Yellow status of « housekeeping »
> for some indexes)
|
Then refer to the applicable troubleshooting document depending on the identified case.
