What does hits in solr logs indicate?

Question

I see below log message in my solr logs

webapp=/solr path=/admin/ping params={} hits=1421599 status=0 QTime=26

o.a.s.c.ShardLeaderElectionContextBase make sure parent is created 
o.a.s.c.ZkController Core needs to recover:

what does hits in this log indicate ?, after this log , I see the cluster went down and failed leader election process. trying to understand is it high volume of reads and writes that took down the cluster ?

Answer 1

The hits in the Solr logs is the same value of numFound returned by a Solr query. In other words, hits represents the number of documents that matches the query.

In your case the hits logged in response of the handler /admin/ping represents the number of documents in the Solr core/replica.
