I have servers located in different physical locations and on different subnets that I need to include in the same cluster. I _can't_ have them in different ganglia clusters because they are handling the same processing tasks. Here is an example:
Cluster1: Cluster2: ServerA ServerE ServerB ServerF ServerC ServerH ServerD ServerI Locations: State #1: State #2: 10.x.x.1: 10.2.2.3: ServerA ServerC ServerB ServerD 10.x.x.2: 10.x.x.4 ServerF ServerH ServerG ServerI (That formatting should look ok on a fixed font) Its seem that may multicast isn't working across the WAN links and I've read it doesn't cross subnets by default (makes sense). I've been trying to figure out how to use the 'host =' statement in the gmond.conf and I can get ServerA and Server C to semi-talk, i.e. I can run gstat -a on ServerC and see the stats for serverA, but A can't see C. I've tried adding them both to the gmetad.conf like "data_source "Cluster1" ServerA ServerC and that doesn't work either. I've tried changing the ports as well. I do have about 5 clusters overall. I can't find anything in the docs that say you HAVE to change the port, but I've tried. Does gmetad only talk to the clients via the "tcp_accept_channel" port? I would appreciate anywho who's done something like this to share their config and their gmond.conf files. I tried modeling mine after here: http://people.web.psi.ch/markushin/hpc/docs/Ganglia_VM_20070116.pdf and the part where it discusses "Unicast can be used when hosts belonging to the same Ganglia cluster are on different subnets, for example", but I'm just not getting something right. I've tried a lot of combinations in gmond.conf and gmeta.conf and still can't seem to get the right one, even after perusing all the lists and googling ganglia to death. :) I'm willing to do anything to my .conf's to make this work right! Just to clarify, the end goal for this config is for only 2 clusters to display in that (only) grid on ganglia.
