So I would check out your multicast config, both in the monitoring core

This very well may be the problem. I am not able to ping 239.2.11.71
on the es40 whether the gmond is running or not. I also have to admit
that I know nothing about multicast... it "just works" on linux so
I never had to muck with it. Oh, and I am able to ping 239.2.11.71
on the linux systems.
So I guess I need to go read a bit about multicast on tru64.
[insert critique of my lack of regard for quoting conventions here.]
It's my understanding (someone please correct me if I'm wrong) that a
ping to a multicast IP should return ICMP responses from every host on
the multicast channel.
In other words [pseudoshell alert]:
% ping 239.2.11.71
64 bytes from host1 (icmp_seq=1)...
64 bytes from host2 (icmp_seq=1)...
64 bytes from host3 (icmp_seq=1)...
64 bytes from host1 (icmp_seq=2)...
And so forth.
It's slightly quicker than using tcpdump, which'd be the next step. :)
