> Key: HBASE-6216
> URL: https://issues.apache.org/jira/browse/HBASE-6216
> Project: HBase
> Issue Type: New Feature
> Reporter: Kannan Muthukkaruppan
> Priority: Major
>
> 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).
> * even in a single app environment, the app may want to tag different API
> calls with different tags even if those calls are to the same CF.
