Hi,
I have 5 clustered nodes and each nodes have 1 replica.
total document size is 216 M and 853,000 docs.
I was suffering from very high CPU usage.
every hours and every early morning about am 05:00 ~ am 09:00
you can see my cacti graph.
there is elasticsearch only on this server
I thought there are something wrong with es process.
but there is a few server request at cpu peak time.
and there is no cron job even.
every hours and every early morning about am 05:00 ~ am 09:00
I don't know what's going on elasticsearch at this time!!
somebody help me, tell me what happened in there. please..
