We have been running ganglia on our apple clusters for years. I have the gmond.conf set to broadcast to the head node without issue (192.xxx.xxx.xxx). I had to play with it a bunch to get it working though. We are running ganglia 3.1.2
This post caught my eye because I had one client that was showing only an IP address. I checked the DNS in server admin and behold the forward for that address had disappeared. No idea why because it worked last time i checked. I've come to expect that from Apple so it's no big deal. >Hi - >I'm running ganglia 3.05 on a cluster built from several Apple Macs >running the Darwin 9.5.0 Kernel. > >I *could* update ganglia, but I'm hoping someone could help me out... >I had this configuration working earlier, but then we moved the cluster >to a different sub-net and I'm having some problems: > >1) I remember when I initially setup ganglia on this system, I was not >able to get things going, and the problem was that I had to use >224.0.0.1 as the multicast address in all my gmond.conf files >(this is a special multicast address that means "all IP hosts"... >I remember trouble-shooting and finding a post somewhere that said this >had to be done on Apple systems... sure enough, if I use any other >multicast address, I cannot "see" any of the machines in the cluster). > >2) The problem now is that when I bring up the ganglia webpage, I see >all the compute nodes just fine, but the head node appears with its IP >address, and not its name.
