So my understanding is that gmond on each node receives UDP messages
from localhost is polled by gmetad via tcp/xml. The wikipedia page [1]
states that gmond also sends data via Unicasting or Multicasting host
state in external data representation (XDR) format using UDP messages.
But I'm having
You choose a single gmond in each cluster as a collector. Gmetad only
polls the collector for each cluster. In unicast mode, you set all
your gmond nodes to send an XDR formatted UDP datagram to the
collectors. In multicast mode, you can choose the collector at random
from gmetad's perspective.
