We monitor 174 hosts, with 2255 services and an average latency off 400 seconds!!!! Off course that’s not exceptable. I use perl plugins with ssh and snmp plugins. I’v compiled nagios with perlcache and embedded-perl enabled. The server is a sparc server with 2 x 1.1 Ghz CPU and 1024 RAM. (Solaris 8, latest patch-level) I played around with all kind of parameters and read the tuning docs for nagios.
