Just found Cacti (http://www.cacti.net/) And managed to set it up in like minutes. I've finally found a decent system monitor. :D

Example tweaked bandwidth graph:

it of course does much more than bandwidth, like processes, disk usage, all that good stuff, and also includes SNMP support :)
looks interesting.
Been using it for years now... its pretty great. :D
Sometimes the addon xml scripts to read in other switches and routers dont always work the first time uploaded.
But it is a lot easier to handle more servers.
