Elasticsearch stats by groups return inconsistent values


(Igor Serko) #1

Environment:

  • 14 nodes
  • 3 indices
  • 15 mil documents
  • ~70 queries/s

I'm querying Elasticsearch search stats on all indexes by stats groups using

curl http://127.0.0.1:9200/_all/_stats/search?groups=_all

I take the query_total values out of the results for each index and group,
however I see that I get different results on every query I do.
See examples at: https://gist.github.com/iserko/9963195

I'm guessing the reason for this could be that it's only getting metrics
from a few nodes instead of all of them.
But if that's the case, can I wait in some way and make sure I have data
from all the nodes?
