> Project: HBase
> Issue Type: New Feature
> Reporter: Kannan Muthukkaruppan
> Assignee: Aurick Qiao
>
> Allow applications to tag individual RPC requests so that metrics exposed by
> HBase can automatically be collected/aggregated by those tags. This'll be
> useful for problem diagnosis across various applications-- as it will allow
> us to correlate HBase metrics (such as data block misses) back to application
> level tags.
> For example, in some multi-tenancy type use case where many different
> applications are served out of a single Table or CF, it'll be useful to know
> the break down of metrics (such as bytes read, data block misses, get/put RPC
> calls, etc.) by application name (tag).
