----------------------------------------------
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
Assigned to: 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.
