Most popular indices/shards

Elastic Stack Elasticsearch
1

Hello Everyone,

I have a busy elasticsearch cluster running 5.3.0. CPU Load is high on 2 nodes and query time as well. Bottleneck seems to be related to I/O. I was wondering, how can I know which indices or shards are the most access? I would like to move busy shards to nodes that are less busy. This would be a temporary solution until I add more I/O's.

Thanks,

Steeve

You can use the indices stats to find out how much time is spent searching per index.

Thanks,

I have hundreds of indexes, how can I return index name, query_time desc? I am struggling with the curl command.

can you explain what your problem is? Which data are you missing to gather information?

How can I use the https://www.elastic.co/guide/en/elasticsearch/reference/5.5/indices-stats.html
via a curl command order by query_time desc?

ordering needs to be done by yourself, this just exposes stats. It is up to you what you do with it.
