Description Siebrand Mazeland 2013-07-30 14:11:32 UTC 
A lack of monitoring on Solr could cause bug 52148 to go unnoticed for a while (about a week).

This issue aims to have Solr monitored in such a way that "unexpected behaviour" would be noticed automatically, and <relevant roles> would be notified, so that service outages would be detected sooner and can be responded to quicker.
Comment 1 Niklas Laxström 2013-07-31 08:43:01 UTC 
I was thinking whether we can have monitors that check the number of documents in the index, and alert if that drops a lot?
Comment 2 Andre Klapper 2014-03-13 13:10:38 UTC 
Elasticsearch won over Solr (see https://www.mediawiki.org/wiki/Search#Solr_vs_Elasticsearch ) so this is INVALID now.
Elasticsearch monitoring is covered by bug 57210.
Comment 3 Niklas Laxström 2014-03-13 14:44:12 UTC 
Andre: this is about TTMServer, which is still using Solr.

However, since we will be working migration to ElasticSearch for TTMServer, it makes no point to work on this bug.
Comment 4 Andre Klapper 2014-03-13 15:10:58 UTC 
Uhm, thanks for clarifying. Wasn't aware of that from the bug description. :(
