You could run the 'sar'
On SuSE this comes from the 'sysstar' RPM
http://perso.orange.fr/sebastien.godard/

The sysstat tools can log system parameters on a periodic basis
for later analysys by the 'sadf' tool.

You could run Ganglia on the machine, we use this for our Beowulf 
cluster monitoring.
http://ganglia.sourceforge.net/
Don't worry - you can run the ganglia monitor daemon and the data 
collector on the same machine.
