Michael, Use different multicast addresses for each cluster, unless you are sure the multicast can't leak from 1 cluster to another.
Remember that when you list hosts after the data_source for gmetad.conf that is for resilience only. You do not have to mention all nodes in the cluster there. Given your symptoms it might be something else. I suggest you consider using unicast initially rather than multicast until you get everything going. (upd_send in gmond.conf pointing to a nominated headnode on each cluser, then data_source from that). And netcatting hosts can be very instructive (e.g. nc lsora1006 8649). Are all expected hosts listed in the nc output? Unexpected hostnames? (gmond does reverse dns lookup to make hostnames). Is the cluster name returned by nc different for every cluster? (the clustername in gmetad.conf is not used). good luck Richard Grevis Production Architecture Barclays Capital, Canary Wharf, London, E14 4BB > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On > Behalf Of Michael Steeevs > Sent: 30 March 2007 15:29 > To: [email protected] > Subject: [Ganglia-general] Not getting something > > > > I'm trying to set up what I hope/think is a pretty straight > forward configuration -- I'm looking to monitor Oracle RAC > via ganglia, and I've got three clusters (Prod, Dev and > Test).
