Hello--
I have installed ganglia on several of our clusters, but it would seem
that the multi-cast channel is pumping a ton of data. On a 96 node
cluster, I am seeing around 20-30Kb/s average data transfer on the
multicast channel ( seen via ntop ). I am _very_ interested in reducing
this, otherwise we will have to remove ganglia. I have seen the 'deaf'
and 'mute' options in gmond.conf, but have not seen a difference while
using them in traffic patterns.
Is there any way to disable the multicast channel, and just have each
node reports stats to one monitoring server ?
Nic
