Tools to monitor linux server

[wheel]

What's available to monitor a linux server? I'm migrating to a new server and I'd like to be able to monitor things like:
- server load
- temperature
- intrusion attempts (maybe)
- network traffic
- raid drives

stuff like that.

I got a CD with the server from supermicro with something called superdoctor, not sure if that's worthfiguring out.

Take a dive in Munin. It is a free package with lots of add ons to monitor all kind of things like CPU and network load, temperatures etc.

I used to use Nagios [nagios.org...] and it wasn't too bad.

Just avoid the classic n00b mistake I've seen done too many times of running the monitoring software dashboard on the same server being monitored.

Ever try to access a monitor dashboard from a server in distress?

Doesn't work! LOL

I ran into a problem running the monitor dashboard from home. It appears the cable company does some of their work at night which sets off all sorts of false alarms for down servers that are perfectly fine.

YMMV

I like Munin. You might be able to get graphs on temperatures and instrusion attempts with the plug-ins on Munin Exchange [exchange.munin-monitoring.org].
