No answer to your question, but I did confirm the bug still exists in 6.4.1. Looking at the code itself, it’s a simple integer division problem when finding the percent. They do ((x/y)*100). Since x/y is always between 0 and 1 (except for 100% usage) and the variables are integers the x/y is always rounded down to 0 before the multiplication. It’s a simple fix so if you register at foundry27 and get access to the code you can fix it yourself. Anyway, I’ll post a bug to QNX so it will hopefully be fixed in a future release.
In the meantime there are a few options I know of, none of which satisfy all your stated requirements, that may be useful.
top -i 1
- top displays the 10 biggest CPU users, by using “-i 1” top will run to completion after 1 iteration
- will display all processes and run to completion showing CPU usage, but displays usage as time rather than percentage
From what I’ve been told, all these utilities do a fairly poor job of measuring actual CPU usage and you should really try to use something like the System Profiler to get more accurate results.
Hope that helps
