I think there is a syslog replacement that can filter on message 
contents try google for that one.

The standard for syslog daemons is to filter by two numbers:
a.b
"a"  has names such as daemon, mail and so on and is called "facility."
"b" has names such as crit, info, debug and such and is called priority.

I think, without checking (but the principle applies) that both are 
16-bit numbers, and it's these numbers syslogd uses to filter messages 
into different file.

What will work is to configure autofs to use on of the "reserved" (aka 
local) ones that's currently unused by RHEL and to configure syslogd to 
log them some place.

It's is possible this will require source-code changes to autofs: read 
the docs to find out whether it is configurable at run-time.

This has the drawback that you have to change autofs each time there's a 
new version (including bug-fixes), that you have a non-standard 
syslog.conf etc etc. Oh, don't forget to rotate the logs!

If you do decide to take the route of changing the code, I recommend you 
make it configurable and offer the patch upstream. If accepted, it might 
ease your maintenance effort in the future.
