Our configuration is quite large (830 hosts, 160700+ services), so have implemented a master/slave configuration for Nagios (the Nagios servers are running Linux). The master server only runs checks if a check becomes stale; i.e. it should have been checked by a slave but no result has been received, but I find that (for example), in the last days log there are 80,000 + warning messages saying the master has run a check because it has become "stale". On further investigation I find that on all of our 5 slaves the command netstat shows that there are a large number of TCP sockets in CLOSE_WAIT state (more . My question is, has anyone done any network tuning to improve Nagios network performance ?
