steve- steve is right on track with the suggestions. it appears that you are running two different versions of ganglia 2.x at the same time. a quick way to get the version of gmond is to run...
% /usr/sbin/gmond --version (or wherever you installed gmond on each machine). so running that command on your entire cluster will let you know which machine is causing problems. multicast is a great way to do group messaging but it is also a victim of its own success. if a single machine in the cluster (aka multicast channel) is not upgraded.. it will be sending old format messages to every host in the cluster (and they will complain as you are noticing now). if you can't upgrade gmond on some of the machines, you can do like steve suggested and place them in a separate multicast group. the multicast group is changed in /etc/gmond.conf... mcast_group 239.2.11.78 for example.. and the multicast port is changed using mcast_port 8650 the default multicast group is 239.2.11.71 and the default port is 8649. good luck -matt Today, Steve Gilbert wrote forth saying... > From: Steve Gilbert <[EMAIL PROTECTED]> > To: "'[email protected]'" > <[email protected]> > Date: Tue, 26 Aug 2003 15:35:24 -0700 > Subject: [Ganglia-general] New user gmond woes > > Hi everyone, > I inherited a large Ganglia 2.0 installation which I am currently > trying to upgrade to version 2.5.4.
