Overhere (Shell Gabon) I am just finishing the installation of the monitoring tool we chose here. It is the Big Brother system & network monitor. This monitors our unix and nt servers, routers and databases.
You can have several tests on the servers, and download plugin tests, like the oracle tests. If you look into the stuff some futher, you will be able to make your own tests which show up on the Big Brother page.
Ruud, thanks for the reply. Looks like pretty cool stuff! Unfortunately, my client is looking for more of a turn-key solution with some vendor backing (no shareware) for long term support and accountability., I'll definitely be looking at it on my own though.
Nothing better and more solid than OEM for Oracle and OS monitoring. We have single OMS that handles more than 100 db instances and never had an issue with not catching a single event before ever happened.
