Subject [jira] Commented: (HBASE-625) Ganglia support for cluster load history: emissions and graphs
Date Thu, 09 Oct 2008 23:26:44 GMT

    [ https://issues.apache.org/jira/browse/HBASE-625?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12638432#action_12638432

stack commented on HBASE-625:

Lets try and go the route of hadoop-metrics. Easy to add our own.  Has support for file and
ganglia.  Out of box does dfs, jvm and job metrics.  Easy to configure.  I can make file work
but not ganglia even w/ HADOOP-3422 applied.  Will be back.

>            Reporter: stack
> hbase should write loadings on a period in a format that is amenable to tools like ganglia
(rrd).  Master can dump cluster loadings and averages.  Regionservers would report their own
loadings.  Should exploit the work up in hadoop for doing this kinda thing (GangliaContext)
where it makes sense.  Extra browning points if user can optionally enable display of graphs
in the hbase UI (JRobin).
