Description christian 2014-04-03 10:18:56 UTC 
Although other worker nodes in the cluster (e.g.: analytics1016 [1])
show Hadoop metric groups like:

* Hadoop.DataNode metrics
* Hadoop.NodeManager metrics
* Hadoop.NodeManager.jvm_memory metrics

ganglia does not show them for analytics1012:

+eqiad&h=analytics1012.eqiad.wmnet&tab=m&vn=&hide-hf=false&mc=2&z=medium&metric_group=NOGROUPS

Should not those metrics also show up for analytics1012?

Comment 3 Andrew Otto 2014-04-04 22:04:31 UTC 
YES!  Found it.  /etc/hosts had a bad IP listed on analytics1012 for itself.  Fixed and things look much better now!
Comment 4 christian 2014-04-07 13:10:05 UTC 
Fixed by Andrew. Ganglia now shows the metric groups and corresponding metrics.
Comment 5 christian 2014-04-07 13:22:07 UTC 
Stupid me. Looked at the wrong host. Sorry.

Reopening: analytics1012 still misses the metric groups of this bug's
description.
