Hello, Elasticsearch friends:

I have to reverse engineer some code that makes use of  
org.elasticsearch.index.shard.IndexingStats, which I believe is  
feeding our graphing layer information on indexing requests per sec and  
reads per second.

The Elasticsearch REST API is pretty well documented, but I  
didn't find much javadoc or any other type of reference for  
org.elasticsearch.index.shard.IndexingStats and similar classes.  
Is there a one-to-one mapping between these classes and corresponding  
elements of the REST API ? (in which case I can consult the REST API  
for answers to my questions.)

Or, if not,

I'd like to ask the following:

- over what time period are the various metrics of
- org.elasticsearch.index.shard.IndexingStats (and similar classes)  
calculated ?
  - from start time of server?
  - for last hour/day/minute?

Can i configure, per call, the interval over which metrics are calculated ?

thanks very much in advance!

Hey,

you can check the `toXContent` method of `IndexingStats`, which is showing you the representation of the JSON when written out.
