How should we interpret the most left column after PID which mean problem process ID from the UNIX world ! for example in the following :

46 1336 350316 3 0.07% 0.00% 0.00% 0 Net Background

1336 as "Runtime(ms)" is it good for this process, is it bad ? why ? what is meaning "Runtime(ms)" exactly same for "Invoked" & "uSecs" column.

Tips:

The command reference provide explanation, the only trouble is to find the right command reference guide.For this commands is the fundamental command reference in the system management section.

Click here for the command reference list.

Another reference link can be found here.

Invoked

#

Number of times that the process has been invoked.

#

uSecs

#

Microseconds of CPU time for each process invocation that is the show provides info about how many microseconds at each call to the routine/process.This is because for example the watch dog process is a guardian that looks at how much time a process uses the cpu.
