Bernard and Alex,
Thanks for the advice. I saw somewhere that you can't have the cluster
name in nagios be the same as the head node.
Is that the case? I thought I had tried the option you recommended
before, but with those being the same and it acted
confused.
Anyway, the option you gave me was perfect to get it working as I wanted.
Thanks,
Jeff

Re: [Ganglia-general] Including a Head Node in Ganglia Monitoring
Hi Jeff:
Aren't you just missing a "udp_send_channel" to itself on head?
Cheers,
Bernard
