MetricsContext counterpart in metrics2 framework

Hi,
Pardon my lack of knowledge about metrics2 framework.

I don't see MetricsContext in src/core/org/apache/hadoop/metrics2

If a user Implements his/her own MetricsContext to plugin to monitoring
system, what should he / she do in metrics2 framework.

Cheers

There is no MetricsContext in metrics2. The functionality of
MetricsContext is split into MetricsSource, MetricsSystem (the pubsub
system) and MetricsSink. Typical monitoring plugins just implement the
MetricsSink interface and register the implementation and topology in
hadoop-metrics2.properties. See o.a.h.metrics2.sink packages for
examples (FileSink, Ganglia3*Sink etc.)

For design docs see http://wiki.apache.org/hadoop/HADOOP-6728-MetricsV2

If anyone is using metrics2 in hadoop 1.0 or 2.0, please share your
experience.

Thanks
