Hi all,
I'm trying to setup a ganglia environment roughly as follows and wanted to know
if this is possible, and if not, the best way to go about it.
In each geographic region, we will have a number of grids / groups of hosts. We
would also like to have a gmetad collector in each region. This would be
viewable using the web config, so on a regions collector, you would be able to
see all grids that report to that gmetad as well as the aggregated view of the
region showing the total hosts.
We then want to have another gmetad that sits above all of this. This would
allow the user to view all grids from all regions and would show a global view.
Is it possible to have one gmetad collecting data from multiple distributed
gmetad machines in different regions?
If not, the alternative solution I am looking at is to have each machine in 2
grids. This would mean having 2 (or more for redundancy) udp_send_channel
pointing to different hosts, and these hosts being in different clusters -
would this work ?
For example, in my gmond configuration on a node, I might have:
udp_send_channel {
host = machine1.domain.com
port = 8649
}
udp_send_channel {
host = machine2.domain.com
port = 8649
}
In my gmetad.conf, I would then have the following:
data_source "Project Cluster 1" machine1.domain.com
data_source "EMEA Nodes" machine2.domain.com
Would this work and show aggregated view of all nodes in the EMEA Nodes grid
and just data for the projects in Project Cluster 1, Project Cluster 2, etc?
Thanks in advance,
