Cloudelastic: alert on inconsistencies between running CCS running state and active master-eligibles
Closed, ResolvedPublic


We changed the cloudelastic master-eligibles in T361305 , but we neglected to update the CCS (cross-cluster search) settings on the running cluster. As a result, users lost the ability to search across the cluster (see T358541 ).

We already check for this on production master-eligible nodes (Puppet code). Creating this ticket to monitor cloudelastic as well.

Change 1012703 had a related patch set uploaded (by Bking; author: Bking):

[operations/puppet@production] cloudelastic: check/alert on cluster inconsistencies

Just capturing a few notes from today's pairing session with @EBernhardson and @RKemper .

We think the best way to do this is to create the cross-cluster data structure on the elastic hosts as json, and have Puppet update the settings when they don't match (using onlyif conditional).

The immediate work is done, although we still need to migrate these checks away from icinga. (See T358029 and T346438.) Closing...
