I have an existing Ganglia installation with two data_sources, corresponding
to two homogeneous sets of cluster nodes.
The relevant lines from /etc/ganglia/gmetad.conf on the head node of this
cluster - call it 'frame' - are:
data_source "no-gpu" node.fqdn (using the default port)
data_source "gpu" node.fqdn:8653
I'm deploying a new cluster - call it 'redman' - and would like to have
THESE nodes show up as a third data source. I'll have 'gmond' on each of the
nodes, and 'gmetad' on the head node, just like I do on the original
cluster.
How should I set up data collection on 'redman,' and how can I configure
'frame' to retrieve that collected data from 'redman'? My first thought
would be to run 'gmond' on 'redman'... but I don't want data from 'redman'
to be collected; it's a head node, not a compute node.
The head nodes of each cluster - 'frame' and 'redman' - are on the public
network, but their nodes are not.
Thanks!
Best,
