Best practices: Logging syslog msgs to central loghost

[Ken Rossman]

We are considering doing some fairly extensive syslog message  
redirection
to a central log host system.

I am interested in hearing some opinions from any folks out there who  
have
done this as to specifically:

- What different message categories do you send to the loghost?  Do  
you send
   every message type, or just certain ones, and which ones?

- What kind of loads are you seeing on the loghost, and on your network
   as a result of redirecting messages to a central loghost?

Any thoughts on this appreciated.
