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.

So my understanding is that gmond on each node receives UDP messages

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 trouble figuring out what this is referring to.
Is it possible to disable gmetad polling and have each gmond push data
to it via UDP?
