Hi!
I need to draw graph of dummynet's CPU usage.
"procstat -t 0" shows me TID (thread id) of dummynet kernel thread.
"ps -Hxo time,lwp" shows me total CPU time consumed by this thread.
Now I see this time has 9 seconds increase during 60 seconds of real time.
This should be 9/60=15% CPU usage, but "top -SHP" shows me 0.00% meantime.
Where is my error?
