> Standard set of Performance Metrics for Hadoop
> ----------------------------------------------
>          Key: HADOOP-237
>          URL: http://issues.apache.org/jira/browse/HADOOP-237
>      Project: Hadoop
>         Type: Improvement

>   Components: metrics
>     Versions: 0.3
>  Environment: All
>     Reporter: Milind Bhandarkar
>     Assignee: Milind Bhandarkar

> I am starting to use Hadoop's shiny new Metrics API to publish performance (and other)
Metrics of running jobs and other daemons.
> Which performance metrics are people interested in seeing ? If possible, please group
them according to modules, such as map-reduce, dfs, general-cluster-related etc. I will follow
this process:
> 1. collect this list
> 2. assess feasibility of obtaining metric
> 3. assign context/record/metrics names
> 4. seek approval for names
> 5. instrument the code.
