[Beowulf] Syslog Server-Traffic

[Eli Stair]

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.
