How do I set the grid name?
Because these are hadoop machines so I used the following
configuration parameters in my hadoop-metrics.properties files:
dfs.class=org.apache.hadoop.metrics.ganglia.GangliaContext
dfs.period=10
dfs.serve...@ganglia@:8649
mapred.class=org.apache.hadoop.metrics.ganglia.GangliaContext
mapred.period=10
mapred.serve...@ganglia@:8649
jvm.class=org.apache.hadoop.metrics.ganglia.GangliaContext
jvm.period=10
jvm.serve...@ganglia@:8649
rpc.class=org.apache.hadoop.metrics.ganglia.GangliaContext
rpc.period=10
rpc.serve...@ganglia@:8649
And replaced the @GANGLIA@ with 10.1.1.25
I didn't install any ganglia stuff on each of the machines. I just
ran Hadoop as I normally do, and configured the above.

And they all are configured with the same grid name? Another
thing to
try is to run gmetad in -d mode and see if its receiving anything.
Yes they are all in the same subnet, all attached to the same switch.
monitor is: 10.1.1.25
the two devices are 10.1.1.128, 10.1.1.129
I tried the telnet test also: from each of the machines that are
monitored, I ran telnet 10.1.1.25 8649, and received the XML file.

Are the monitored nodes on the same side as the monitoring

not you might have to explicitly turn on mulicasting in the router.
Depends on the router.
