I just set up NetSaint this morning to monitor some servers, and I am really impressed with it. It took me less than 2 hours to set up to monitor an entire network, and that included reading the (very good) documentation.
You can monitor ping results, system loads, disk space, users, zombine processes, HTTP, PostgreSQL, etc. etc. etc. on Linux/other UNIX boxes, Windows boxes, and printers. The results can be viewed from the command line, or through CGI scripts. The CGI scripts show network status maps (all your servers at once) and can even show them using VRML! This thing is awesome! Alerts can be sent via e-mail or pagers.
