You've given no indication of which Operating System you're using but I'll take a guess at CentOS, feel free to correct me if that's wrong. You also don't say whether you've installed the required sysstat package, have you? Did you search the forums for this problem before you posted? This has been covered before.
BTW, please use a more descriptive title for your thread in future I've changed this to something more appropriate.
