No sir, management nodes will unicast to the local ganglia server. The others will multicast. So, where the other servers will only have one line in the gmetad.conf, this one will have two.
The reason I am trying to make it work this way is that we do not want gmetads running on compute nodes. On the big cluster we us unicast and it has start becoming onerous. --- On Fri, 10/10/08, Bernard Li <[EMAIL PROTECTED]> wrote: > From: Bernard Li <[EMAIL PROTECTED]> > Subject: Re: [Ganglia-general] New Cluster Issue > To: [EMAIL PROTECTED] > Cc: [email protected] > Date: Friday, October 10, 2008, 2:01 PM > On Fri, Oct 10, 2008 at 11:16 AM, Buccaneer for Hire. > <[EMAIL PROTECTED]> wrote: > > > We have a new cluster-1250 compute nodes, 10,000 cores > in 3 rows.
