Syslog Watcher Personal Edition 2.8 (cheap ie free like me).

Not so much a recommendation more that it works, is simple, didn't need some monstous SQL backend or some obtuse version of dotnet to install. That's fitted my scenario.
Gives me very basic syslog info/reporting. Enough for me but you might prefer something cleaner and with more bells/whistles/pan pies.
Doesn't interpret the cryptic ruckus message codes but I wasn't expecting an easy life!
