Let's say I have two hosts. One acts as the server where gmetad and a local gmond resides. It also has the web interface. I then have a client that only has gmond configure as follows.

Anyways, everything works fine if i remove the mcast_join line from the udp_recv_channel If I leave it as is the UI doesn't show any hosts. I'm following the quick start guide found here

In my gmond.conf file i have the following.

udp_send_channel {
  mcast_join = host1
  port = 8661
  ttl = 1
}

udp_recv_channel {
  port = 8661
  retry_bind = true
  mcast_join = host1
  bind = host1
}

In my gmetad.conf file i have.

data_source "Infrastructure" host1:8661 host2:8661
