.. i forget that sometimes the multicast problem can be caused by gmond network interface defaults. if the frontend node is multi-homed (has two network interfaces).. gmond will listen/announce on the first multicast-enabled network interface. if your cluster is on a private network multicasting on the second network interface, the frontend will not know about it.
the solution is simple.. explicitly state the network interface on the frontend box.. e.g... in /etc/gmond.conf put the line mcast_if eth1 for example, if eth1 is the interface connected to you private cluster. -- matt Today, Bo Liu wrote forth saying... > Hi, > > I installed gmond, gmetad and ganlia python client on > my cluster.
