To expand on what Jason wrote, the name doesn't actually decide which
cluster the node's data gets included in. If you are using multicast as
it appears you are (my guess), You will need to take an additional step
of segregating each cluster by using different ports. With your example:
gmetad.conf
data_source "Servers" 60 localhost:8649
data_source "Opterons" 60 hsd380:8655 hsd400:8655
data_source "Athlons" 60 hsd250:8656 hsd258:8656
Opterons gmond.conf
udp_send_channel {
mcast_join = 239.2.11.71
port = 8655
}
etcetera

Ganglia developers,
I am trying to implement Ganglia on a 500+ node cluster. My goal is to use the
grid functionality to have the data split up into several groupings (by
architecture -- it is a non-homogeneous cluster). The issue I am having is
that every one of my nodes is showing up for all “data_source” definitions. In
other words, the metrics from all ~500 nodes shows up under each data_source
heading even though I have defined distinct “cluster names” in the
/etc/gmond.conf files.
My config files are provided below for reference.
Thanks for any advice you can provide,
Mike
