Elasticsearch slow query responses


(Andrei Stalbe) #1

Hi there,

We have a problem with our ES cluster. (see the attached screenshot) As you
can see there is a node on red 99% CPU, and it changes from time to time, I
mean there isn't only one server on 99%, one can "calm down" another is
stressed up and raises to 99% CPU. I have attached also an htop for the
stressed server. The slowlog does not show anything suspicious though some
respunses take more than 3 seconds to complete.

Please advise!
