Hi Carlos, I think that the problem you have here is that you're not using the right IP addresses. Ganglia monitors use a IP multicast address (default is 239.2.11.71, can changed via the -mcast_channel, as you have noted). 10.x.x.x addresses are not multicast, a multicast address is one in the range 224.0.0.0-239.255.255.255.
I suggest a couple of solutions: 1) add in each host a route for 239.2.11.71 (or whatever IP in the multicast range you want to use) that goes to the management network interface route add -host 239.2.11.71 eth1 2) add a route for the whole multicast range of addresses towards the management interface: route add -net 224.0.0.0 netmask 240.0.0.0 eth1 hope this helps kind regards, On 14 May 2002 17:33:23 +0200 Carlos Javier Ramos <[EMAIL PROTECTED]> wrote: > Hello ! > > Im trying to monitorize a LVS cluster using ganglia. > > Each machine in the cluster are connected to different networks. > > Master Load balancer 1 > - intranet network ( <- default route) > - data network > - management network > > Slave Load balancer 2 > - internet (only active if Master is down!) > - data network (only active if Master is down!) > - management network > > > Real Server 1 (Master Load balancer data network is default > route)- data network > - management network > > Real Server 2 (Master Load balancer data network is default > route)- data network > - management network > > > Monitoring Box > - management network > - intranet network.
