Description
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.
