Im currently usig ubuntu as a server, and i use gnome-system-monitor to track (visually) how much cpu load is being consumed, however, I only see the last 60 seconds of usage.

Is there a way to set the gnome-system-monitor to remember the last 300 seconds (or some other value)?

Thanks,

Not within gnome-system-monitor, no and it's actually an awful tool for monitoring resources long-term because it consumed so much CPU.

I suggest you take a look at munin. It's a simple little tool for monitoring resources on a server. It creates graphs (not as pretty System Monitor) and logs things over a long time. It generates static HTML files on a periodic basis (every 5 minutes, IIRC) which you can either browse locally or you can serve via Apache (et al) so you can view the stats over the network.

You can see more about munin in another answer of mine.

The program sar or atsar also might be helpful. You can start them in a terminal or shell. The option -u shows information about CPU. The last the options are the time between updates and the number of data points you'd like to have.

atsar -u 15 9999999
21:06:20  cpu %usr  %sys  %nice  %idle                          _cpu_
21:06:35  all    5     2      0     93
21:06:48  all   48     4      0     49
21:07:03  all   59     3      0     37
21:07:18  all   65     4      0     31
21:07:33  all   53     4      0     42
21:07:48  all    8     2      0     90
21:08:03  all    5     1      0     94

Depending on your font size and the size of your terminal you'll see the last 300 seconds (20 measurements) of your CPU life.

Another useful tool is dstat. It is quite similar to atsar, but is quite more powerful. If you want to get CPU information, enter:

dstat -c 

----total-cpu-usage----
usr sys idl wai hiq siq
 17   3  78   2   0   1
  7   2  88   3   0   0
  6   2  89   2   0   0
  5   2  91   2   0   0
 15   3  79   3   0   0
 17   3  75   5   0   0
 21   3  73   3   0   0

dstat has colored output. So you can see quite easily if there is too much load or any other problem.
