Bill Graham commented on CHUKWA-515:
------------------------------------
I'd like to return the 1 minute and 5 minute average data rates for each
adaptor.
To do this I was planning on saving off the last 5 minutes worth of
timestamp/offset pairs for each adaptor, so stats could be generated. This
would be done in the {{ChukwaAgent}} in the {{reportCommit}} method. Let me
know if you see problems with this approach, or if there's a better way to go
about this.

> Project: Chukwa
> Issue Type: Sub-task
> Reporter: Bill Graham

>
> Develop a REST interface to expose Agent statistics.
> * Request URI:
> {noformat}
> GET /rest/v1/adaptorStats HTTP/1.0
> {noformat}
> * For now I'm shooting for the XML response, but ultimately we can support
> optional params:
> {noformat}
> viewType=[json|xml|text] (default is XML?)
> {noformat}
> * Response XML
> TBD. My thought is to integrate with the {{AgentMetrics}} and
> {{ChunkQueueMetrics}} and show their information, along with a list of
> adaptors. It appears that the same {{MemQueue}} is shared amongst all
> adaptors, so we won't be able to expose per-adaptor stats as is. Let me know
> if I'm missing something there, or if you have comments in general about the
> approach.
> I was planning on using Jetty similar to how the collector does. We could
> have some common code that delegates requests to different handlers based on
> the URI. The current telnet interface will remain as-is.
