I don't think You want to run it every night. Such snapshots will give You nothing.
Use monitoring tools like mrtg http://www.mrtg.com/

#!/bin/bash

/usr/bin/free -m # show memory and swap usage
/bin/df -m # show disks usage
/usr/bin/top -bn1 #mem,swap,cpu and user processes

about cpu usage, do You want current, average from last ?? seconds, from system startup?
