Once the patch is applied you should start seeing the ganglia metrics
We do.

Once I have the patch applied and have it running should I see the
metrics? Or do I need to additional work?

I have been attempting to get Hadoop metrics in Ganliga and have
been unsuccessful thus far. I have see this thread
(http://mail-archives.apache.org/mod_mbox/hadoop-core-user/200712.mbox/raw/[EMAIL PROTECTED]/)
but it didn't help much.
I have setup my properties file like so:
[EMAIL PROTECTED] current]# cat
conf/hadoop-metrics.properties
dfs.class=org.apache.hadoop.metrics.ganglia.GangliaContext
dfs.period=10
dfs.servers=127.0.0.1:8649
mapred.class=org.apache.hadoop.metrics.ganglia.GangliaContext
mapred.period=10
mapred.servers=127.0.0.1:8649
And if I 'telnet 127.0.0.1 8649' I receive the Ganglia XML
metrics output without any hadoop specific metrics:
[EMAIL PROTECTED] current]# telnet 127.0.0.1 8649
Trying 127.0.0.1...
Connected to localhost (127.0.0.1).
Escape character is '^]'.
?xml version="1.0" encoding="ISO-8859-1" standalone="yes"?>
!DOCTYPE GANGLIA_XML [
!ELEMENT GANGLIA_XML (GRID|CLUSTER|HOST)*>
!ATTLIST GANGLIA_XML VERSION CDATA #REQUIRED>
!ATTLIST GANGLIA_XML SOURCE CDATA #REQUIRED>
--SNIP--
Is there more I need to do to get the metrics to show up in this
output, am I doing something incorrectly? Do I need to have a
gmetric script run in a cron to update the stats? If so, does
anyone have a hadoop specific example of this?
Any info would be helpful.
Thanks.
