John, I assume you have configured for multicast and the multicast address you use does not travel outside the local subnets? That is your current situation?
option 1 is to make a multicast address on the routers that scopes to all your subnets. option 2 is to unicast to 1 or 2 nominated headnodes. It turns out that the UDP traffic is pretty network efficient - much more so than the XML streams. So there is little to fear wrt network loads. kind regards, richard > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On > Behalf Of john allspaw > Sent: 23 September 2006 01:06 > To: ganglia-general@lists.sourceforge.net > Subject: Re: [Ganglia-general] how to get machines from > different subnetsinto same cluster > > > Sorry, more info on what I *thought* was the solution: > > I try running gmetad on www11 (on subnet2) , so that it can > be polled by the frontend box (on subnet1) via TCP on port > 8651.
