I have a question regarding statistics which can be shown using such query: 'curl localhost:9200/_stats'
It should return high level aggregation and index level stats for all indices. In my case it returns an error:
Worth of mention is that all specific stats are working properly e.g. curl http://localhost:9200/_stats/indices shows proper data.
There is only problem with all statistics.I am using 1.5.1 version.
