ElasticSearch Get Index Names and Store Size
I realize this question dates already, but wanted to add my 2 cents.
http://localhost:9200/_cat/indices?h=index,store.size&bytes=kb&format=json
Would actually get you exactly what you requested:
- format=json -> formats the output to json
- bytes=kb -> outputs the size in kilobytes
Information regarding the size unit was retrieved from cat APIs doc
Possible values for the bytes argument
Information regarding the format was an attempt in Sense, which has some auto-completion features quite useful to detect such options.
Cheers.
Index size in bytes is included with an indices stats API call:
curl http://localhost:9200/_stats/indexing,store
For nicely formatted JSON output, append ?pretty to the end of the URL:
curl http://localhost:9200/_stats/indexing,store?pretty
See the Indices stats API documentation for additional details and related information.
Just a slight modification from above answer.
curl -X GET "localhost:9200/_cat/indices?h=index,store.size&bytes=gb?pretty"
