Subject [jira] Created: (HADOOP-5848) JMX Metrics For TaskTracker
Date Fri, 15 May 2009 16:39:45 GMT
JMX Metrics For TaskTracker
---------------------------

                 Key: HADOOP-5848
                 URL: https://issues.apache.org/jira/browse/HADOOP-5848
             Project: Hadoop Core
          Issue Type: New Feature
          Components: metrics
            Reporter: Edward Capriolo
            Priority: Minor


Create useful metrics for the TaskTracker Component. 
* TasksStarted: Counter
* TasksFailed: Counter
If graphed, having these metrics will help administrators determine graphically how task load
is being spread. Also will help determine if certain nodes have external conditions that are
causing a task to fail.
