Well, I personally like the syslog protocol for all "non-critical"
logging. It's easy to setup, can be routed easily and it's so simple
to use that almost every tool under the sun understands it.
It has two flaw, though: First, it's UDP and, as such, can be flooded
and is difficult to verify. The second problem is that it's almost
impossible to secure as such.
An alternative is to use SSL to tunnel and relay syslog messages. If
you use client certs, then you can add authentication and security (at
the cost of performances).
