Enis Soztutar commented on HBASE-9774:
--------------------------------------
Liked HBASE-14282 which is just ripping metrics. This patch will give us DW
based metrics first in the code base, then we can incrementally move to using
more and more internal stuff and eventually contain everything for metrics2 in
the hadoop-compat module.
> Provide a way for coprocessors to register and report custom metrics

> Project: HBase
> Issue Type: New Feature
> Components: Coprocessors, metrics
> Reporter: Gary Helmling
>
> It would help provide better visibility into what coprocessors are doing if
> we provided a way for coprocessors to export their own metrics. The general
> idea is to:
> * extend access to the HBase "metrics bus" down into the coprocessor
> environments
> * coprocessors can then register and increment custom metrics
> * coprocessor metrics are then reported along with all others through normal
> mechanisms
