Ganglia does not partition clusters based on "name", it is actually by
"port". So even though for your pc2, you configure the name to be
"work-cluster", the port is the same as mgmt-cluster, which is 8649.
What you need to do is change work-cluster's port to something other
than 8649 (you can use 8650, or something else, just stay away from
8651 and 8652 as those are default Ganglia gmetad ports). You will
also need to modify your data_source line slightly by adding the port
and host, i.e.:
data_source 10 "work-cluster" pc2:8650
I am not too familiar with unicast setup, but I believe for your pc2
gmond.conf, you should change host to pc2 and port again to 8650.
This should give you the desired setup.
Hope this helps.
Cheers,
Bernard
