Some time ago I was using netsaint (now: nagios). It's free. They have some features around 'flapping', where a faulty conditions comes and goes. You can configure a treshold before getting paged. There seem to be some nice plugins to Oracle as well, we interfaced to existing scripts, though.
Yup, that's what we use as well: nagios. And Sitescope for the most basic monitors.
