I am trying to configure ganglia to monitor a cluster. My initial
thoughts were to have a gmond running on each of the compute nodes,
and to have a gmond running on the head node which would aggregate the
data from the compute nodes and add it's own monitoring data.
The problem I am having is that it kind of appears that I have to choose
to either aggregate the data at the head node, or monitor the head node,
but I can't seem to get both working at the same time.
I am using the unicast option.
On the compute nodes:
cluster {
name = "my cluster"
}
host {
location = "unspecified"
}
udp_send_channel {
host = head
port = 8649
}
tcp_accept_channel {
port = 8649
}
On the head node:
cluster {
name = "my cluster"
}
host {
location = "unspecified"
}
udp_recv_channel {
port = 8649
}
tcp_accept_channel {
port = 8649
}
Then I have a gmetad running on a seperate server with the following in
it's gmetad.conf:
data_source "my cluster" head
Any help or suggestions would be greatly appreciated!
