We’ve been using Nagios for just over a year, monitoring just over 1500 systems, the largest of which is a Z/OS mainframe and the smallest is a POS terminal (actually, the smallest are probably the printers). The 5.700 service checks for these productional systems include such for SMTP, LDAP, HTTP, disks, CPU and quite a number of custom made checks. Apart from the fact that Nagios is FLOSS, the beauty of the program is the simplicity with which the most exclusive of wishes can quite easily be implemented by writing a new plugin in almost any desired language.
