Hobbit: spin off of Big Brother (Score 1)

I currently monitor about 250 hosts with Hobbit (http://sourceforge.net/projects/hobbitmon) and have had good success with it. It has trending (RRD graphs) and alerting thresholds (ie 85% full, email, 95% full pagers) built in together. It is also customizable. We have created several perl scripts that check random applications for various things that are also tracked with Hobbit. How much data Netbackup backed up last night. How many users are logged into our portal. Are the tape drives within Netbackup up or down? The list goes on and on. It runs on Unix and Windows, although the Windows client isn't as robust.
