I don't think its painfully obvious, but my guess is that it your two
vlans either do not talk to each other via multicast or your the ttl is
not set high enough for the multicast messages.
Solution A:
configure your routers to allow multicast communication between the two
vlans. (out of my league)
Solution B:
increase the Time To Live or ttl on the gmond multicast packets. This
assumes that multicast packets can get from one vlan to the other. The
configuration option used to be available in the 2.x codebase, but I
don't see it in 3.0.x code. I think it would be mcast_ttl but I can't
say if that will work or not.
Solution C:
separate the two vlans into two clusters:
data_source "vlan1_cluster" 10 192.168.119.167:8653
data_source "vlan2_cluster" 10 192.168.122.190:8653
Solution D:
ask Rick suggested unicast is available.

ive been trying to get a 120 node cluster recognized on our grid, but
depending on the order listed in gmetad.conf - only 0-59 or 60-119 show
up on the php cluster report.
coincidentally 0-59 and 60-119 are on different vlans, i have both
listed in gmetad.conf as the documentation seems to allow mixed data
sources but only 60 nodes show up depending on which data source is
listed first. am i missing something painfully obvious?
data_source "a_cluster" 10 192.168.119.167:8653 192.168.122.190:8653
thanks
