[Ganglia-general] Unable to see nodes
Hi, I am running a cluster with Ubuntu 12.04 and I installed gangila 3.4.0 from the tarball provided on the site. I installed gmetad and gmond onto my head node, and gmond onto each of the compute nodes. I am able to see my head node just fine from the ganglia interface, and can view the various metrics for the head node. However, I cannot see any of the nodes, even though I am running gmond on all of them. The gmond.conf file is identical on the head node and all the nodes. I tried all the debug steps found here http://sourceforge.net/apps/trac/ganglia/wiki/FAQ and everything works as it should. The only difference was that I need to use nc hostname 8651 rather than 8650 to see the XML data from the head node. Other than, everything seems to be working. I can post my gmond.conf file if that will help, or any other info for that matter. I think ganglia is amazing and would really like to get it up and running. Any suggestions would be appreciated.

Re: [Ganglia-general] Unable to see nodes
Hi Eric: By default gmond is configured to run in multicast mode. If you can only see your head node, chances are multicast does not work in your environment. When you nc to port 8651, you should see XML of not just your head node, but other hosts and their corresponding metrics as well. And 8651 is the correct port for gmetad non-interactive port, not sure who put 8650 there because that's wrong. Try setting up unicast and see if that works.

This sounds like you are running multicast - can you confirm that you're running in multicast mode? If you are running in unicast mode then the config for all the nodes probably shouldn't be identical. If you aren't sure then yes, you should post your gmond.conf. It would also be helpful to see what you have configured in gmetad for your clusters. -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
