Hi,
I'm having trouble with dealing an odd pattern of load distribution on one of our clusters. I inadvertently posted in the wrong forum. Link is here:
FYI we have 18 data nodes, 1250 shards and a limit of 3 index shards per node. So the loading pattern doesn't appear related to shard distribution.
are you doing a lot sliced scroll searches? The hot threads output seems to indicate that? Are you only hitting this one node with sliced scroll queries?
I think trying out to figure who is accessing your data sounds like a good idea. A scroll search is usually not issued by kibana (i.e. for a dashboard), so someone/some code needs to trigger this explicitely.
As for Elasticsearch this is simply an open TCP connection, maybe using some more lowlevel tools could help, like tcpdump or netstat?
This instance is not exposed to the internet I suppose? So you control who can access it?
