Thanks for pointing me to that article.

You address the generation of notices based on certain syslog events, but
I'm missing syslog analysis (strange events, graphing of quantity of certain
types of events over time) and snmp trap translation.  I looked again
snmp-tt, but boy, they're not making it easy.  I want to be able to have a
MIB directory and have the utility generate plain-text output, but looks
like I need to run a translator against each MIB.

Perhaps I need to continue incrementally -- syslog-ng to notify me on
certain types of events, and keep adding tools for each case.  I reviewed
OpenNMS and most of the other opensource graphical tools, they're left
wanting in terms of SNMP trap handling.

You are running syslog-ng, so you already have the capability to
define a perl script or similar as a destination that takes filtered
alerts and pipes them into an email. Or an SMS. Or do basically
anything you can write in Perl.

Nate Campi has put a lot of thought into this and more:

Suddenly it seems your search narrows to some trending work vs.
notifications that you can augment with syslog-ng out of the box.
