Any ideas as to why? > Maybe your CPU isn't doing anything :-} Seriously, I have top from the 2.1.0 packages installed and I get the following initial header on a system here: load averages: 0.00, 0.00, 0.00 15:00:39 63 processes: 1 running, 61 sleeping, 1 zombie Cpu states: 0.5% user, 0.0% nice, 0.5% system, 0.2% interrupt, 98.9% idle Memory: 18M Act 3068K Inact 5696K Wired 536K Free 100% Swap Addmittedly this system is lightly loaded but with 61 (small) processes running, I do get a non-zero % CPU utilization. This system is a WWW server. Unless you are running something compute intensive (compiling for instance), your load is probably too small to show up. I also suspect the absolute accuracy of any of these sorts of programs, they are best used as relative measures. You can also get %CPU from : ps -Saux -- | John Lucas jlucas@uvi.edu | | Information Technology NIC Handle: JL423 | | University of the Virgin Islands (809) 693-1216 | | St. Thomas, VI 00802 http://www.uvi.edu/jlucas.html |
