Overview
Metrics are statistical information exposed by Hadoop daemons, used for monitoring, performance tuning and debug. There are many metrics available by default and they are very useful for troubleshooting. This page shows the details of the available metrics.
Each section describes each context into which metrics are grouped.
The documentation of Metrics 2.0 framework is here.
