We currently have ~850 host and ~13000 service checks running on a single, standalone server. The hardware is nothing fancy, a plain HP ProLiant DL360 G5 with 8GB of RAM. You should be fine with a single server, but there are a few things to look out for: * The 'enable_environment_macro' should be set to 0. Enabling this config option seriously increased the load on our server. * PNP4Nagios and similar addons may significantly increase the load on your server. We collect perfdata and use PNP4Nagios for only a few select services. * The Nagios embedded perl interpreter (ePN) was a major PITA, it leaked memory and we ended up compiling Nagios without ePN completely. * You may have to adjust the command_check_interval and similar config settings. * We mostly use NRPE plugins and only monitor UNIX/Linux hosts. You may have to take care not to use plugins that consume a lot of resources on your Nagios server. These are the only tuning tips I can think of for now, but YMMV :) We don't use distributed monitoring, but are looking into it. When a more streamlined clustered Nagios setup becomes available for production use (probably with the Merlin backend), we will definately be interested.
