My apologies for the delayed response. I thought that I had already replied to this message.
You should look at the log file (/var/log/condor/GangliadLog) to see how many metrics are being sent.
The default installation only monitors the Central Manager and Submit nodes. If you have a large pool, getting many metrics from all the execute nodes can overload the ganglia system.
You can get additional metrics by setting GANGLIAD_VERBOSITY to 1 in your configuration file. The default is 0, which is pretty bare bones. The value 2 contains many metrics. You can see which metrics go out a the different verbository levels in /etc/condor/ganglia.d/00_
METRICS boolean can be used to suppress execute_node metric (while still keeping the aggregate counts).
Hopefully, this make sense.

We have a cluster with all nodes with CentOS 7. I would like to monitor its usage using Ganglia.I configured the Ganglia server in the HTCondor collector. This is working, I can access the web service and see some information.
I also installed Ganglia in a few nodes and I can monitor their status (cpu usage, memory, disk, etc), but the metrics of Condor doesn't show up in the web interface.
In fact, what I don't know is which configuration is needed within Condor to send its metrics to Ganglia. The only thing I did was, in the Condor collector, enable the GANGLIAD daemon. The service is running, but I can't see anything related to Condor in the web server. I do know that there exists a file /etc/condor/ganglia.d/00_
default_metrics but how do we use this file to define things to see in Ganglia? What I am missing?
