I'm back here today just as a reminder that I actually have this blog, and while I am at it I would like to mention two very nice tools for monitoring your system resources : GKrellm System Monitor, and Htop.
GKrellm is a visual representation of pretty much all the necessary stuff you want to keep an eye on. CPU core's usage and temperature's, your Ethernet, and Disk Drive's activity. This is not something you absolutely have to have, but it sure can come in handy from time to time.
Htop, is without a doubt a must have to be stashed within your Lil Bag of Linux Tricks, a complete listing of all currently running process's with the ability to selectively change priority or kill the process completely or only selective portions.
