[jira] [Resolved] (HDFS-242) Improve debugabillity

     [ https://issues.apache.org/jira/browse/HDFS-242?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Allen Wittenauer resolved HDFS-242.
-----------------------------------

    Resolution: Incomplete

I'm going to close this as stale.  Many more metrics are now pumped up through the RPC channels.  It would probably be better if each missing metric was handled as a separate JIRA given the amount of work required to add some of these requests.

> Is there a plan to provide an option to enable metrics (both system and application level) collection on the JobTracker and NameNode from TaskTrackers and DataNodes respectively? Visualizing this data can help us understand what is happening on the various nodes in the cluster in terms of CPU, Memory, Disk Utilization, Network IO etc and possibly spot issues when cluster performance degrades.
> Any thoughts on this are welcome.
