Basically you need to have each cluster on a different multicast port
like so (the xml ports are the same for administrative ease).
Super:
name "Super"
multicast channel: 239.2.11.71
multicast port: 8660
data node: super01
XML TCP port: 8660
Duper:
name "Duper"
multicast channel: 239.2.11.71
multicast port: 8662
data node: duper01
XML TCP port: 8662
Then make sure the data source machines allow access to their XML TCP
port by listing them in the trusted_hosts directive within the
gmond.conf like so
So duper01's gmond.conf would have to have this entry as well as the
multicast ports be seperate
trusted_hosts <gmetd host>
every host on Duper needs to be configed to port 8662 (or whatever you
choose)
every host on Super needs to be configed to 8660 (or whatever you
choose)

Subject: [Ganglia-general] 2 clusters,how to see as 2 cluster separate
as possible
Have 2 clusters on the same subnet. Super and Duper let's say.
How can I best configure /etc/gmetad.conf on the polling server and
/etc/gmond.conf on the clients to not mix data. Want to see these se 2
different entities.
Would like these 2 cluster to be as separate as possible.
Is in /etc/gmetad.conf editing
data_source "Super Cluster" super01 super02
data_source "Duper Cluster" duper01 duper02
The best/only way to separate them?
I do understand that /etc/gmond.conf can be edited like this:
on Super:
/* If a cluster attribute is specified, then all gmond hosts are wrapped
inside
* of a <CLUSTER> tag. If you do not specify a cluster tag, then all
<HOSTS> will
* NOT be wrapped inside of a <CLUSTER> tag. */
cluster {
name = "Super"
owner = "unspecified"
latlong = "unspecified"
url = "unspecified"
}
on Duper:
/* If a cluster attribute is specified, then all gmond hosts are wrapped
inside
* of a <CLUSTER> tag. If you do not specify a cluster tag, then all
<HOSTS> will
* NOT be wrapped inside of a <CLUSTER> tag. */
cluster {
name = "Duper"
owner = "unspecified"
latlong = "unspecified"
url = "unspecified"
}
Is there more that can be done? I don't understand the Multicast channel
part. What if anything should I edit there to separate?
