The main goal was to monitor everything! And with everything they ment, everyting.
We ended up with a complete check_mk farm of 5 servers, using the distributed monitoring function we could easily scale.
1 main check_mk server hosting the webinterface and monitoring linux systems

later on we also added customers with on-site check_mk servers, using VPN to communicate to the main check_mk server so everything was on 1 big pile.
Hosts monitored: 921
Services monitored: 39.907
on-site check_mk: 9
