Hi Sa,
Are you really sure "w2" is a real hostname, something that is
resolvable from the system where you are running this. The JSON output
you posted seems very close to the example from the jmxtrans project
page https://code.google.com/p/jmxtrans/wiki/GraphiteWriter, so I
suspect you aren't using the right hostname.

Hi, All
I installed jmxtrans and graphite, wish to be able to graph stuff from
kafka, but firstly I start the jmxtrans and getting such errors, (I use the
example graphite json).
./jmxtrans.sh start graphite.json

The graphite.json
{

"port" : "1099",
"host" : "w2",
"queries" : [ {
"obj" : "java.lang:type=Memory",
"attr" : [ "HeapMemoryUsage", "NonHeapMemoryUsage" ],

} ]

Anyone help me to diagnose what this problem is?
thanks
