Monitoring tools with pretty graphs.

[reddragdiva]

We need a system and network monitoring tool that generates graphs that are (a) useful to us the drones but (b) pretty to show The Mgt. I know there are any number of monitoring things that generate PNGs in real time. What do you use?

Wikimedia uses Ganglia, which generates just the sort of thing we're after, but the description of the application looks a little heavyweight for under ten Solaris boxes. Of course, I'd be happy to hear that this was not the case.

Update: We also need to check stuff like number of users on Oracle, but that should be a simple check every five minutes, assuming it can log arbitrary data.
