An easy way to keep tabs on your system is through the program top. The top is a little app that can display the processes currently running, how much
RAM, processor and how much
CPU time they are taking (just like ps aux). First, let’s start off by starting it up.
[root@rd ~]# top
This should bring up a nice looking program that shows us much of what ps aux shows us but updated every second. You can change the time between updates by pressings, then typing in the seconds between updates (Note: you can use decimal numbers like 0.5). To switch to command mode display, hit c, and to sort by
CPU time hit T.
The top is very useful in tracking what your resource hogs are, and what your
RAM and Swap usage is. Play with it, the top’s a neat little program.
