alert notification mechanisms

Greets:

I'm curious about experiences of others utilizing various alert 
notification systems on Unix platforms.  I like to log to use acid, but 
also would like some automated notification.  

It seems there are two basic strategies for this; write alerts to logs 
and doing some regexp post processing with the likes of swatch or 
logsurfer, or pipe alerts through syslogd.  I've defaulted to swatch in 
the past, but am interested in exploring more modern options.  
Especially since the most recent release of swatch sports the throttle 
bug.  Logsurfer can get get kind of fat on the resources and get 
complex in a hurry.  

The syslogd approach makes it easy to mail/exec on various triggers, but 
doesn't support throttling.  So you end up turning to syslogd 
replacements like syslog-ng or msyslog.  The msyslog approach looks 
like it could have some interesting potential, since you can chain 
together various processing modules like regexp, classic, mysql, etc., 
and it basically follows syntax of existing syslog.  I am reluctant to 
replace something as sensitive as syslogd on a security sensitive 
application, however, particularly since opendbsd, the platform it was 
developed on, doesn't even sport it in it's port collection....

Any thoughts/experiences you fellow Unix geeks would like to share?  
Thanks bunches.
