If you engineer the config well, you won't have any significant amount of
"insignificant" traffic. Whether your situation is vulnerable to minute amounts of
traffic and client-side processing of packets sent is site-specific.
Using syslog-ng (or several other options), you can configure the compute nodes to
only send log messages you want to be aware of (or restrict from sending known
messages you don't want logged), as well as doing rate-limiting to avoid spamming
your network/logserver in the event of a typical freak-out event.

Hello,
I'm researching setting up a cluster and I'm curious as to whether or
not it's a good idea to set up a syslog server. The question I have
is whether the traffic created from logging is going to slow down my
network to the point of poor performance? What are peoples
experiences with logging. The cluster will have a management network
and a computational network.
This is what I'm thinking:
Greater than 64 Nodes, Yes.
Greater than 64 and less than 128, Maybe?
Greater than 128 No
Any input would be great, Thanks!
