[Ganglia-general] Using gmetric but the metric doesn't appear in the xml file

[cifroes]

Hi,

I'm trying to use gmetric to add a new metric (Tomcat server %cpu usage)
I'm running this command to add the value:
gmetric -n "tomcat_cpu" -v "0.4" -t float -u "%cpu"
every 10 seconds.

when I do telnet localhost 8649|grep tomcat nothing appears... What's 
wrong and how can I add this metric so that it appears in the xml file???

ganglia 2.5.7
other machines in the cluster don't have this metric (and I don't them 
to have it).

Thanks in advance,
