Due to implementational limitations, actions might be delayed
|
|
up to one second after tracing is stopped.
|
|
|
|
**-a**, **--auto** *us*
|
|
|
|
Set the automatic trace mode. This mode sets some commonly used options
|
|
while debugging the system. It is equivalent to use **-s** *us* **-T 1 -t**.
|
|
|
|
**-p**, **--period** *us*
|
|
|
|
Set the *osnoise* tracer period in microseconds.
|
|
|
|
**-r**, **--runtime** *us*
|
|
|
|
Set the *osnoise* tracer runtime in microseconds.
|
|
|
|
**-s**, **--stop** *us*
|
|
|
|
Stop the trace if a single sample is higher than the argument in microseconds.
|
|
If **-T** is set, it will also save the trace to the output.
|
|
|
|
**-S**, **--stop-total** *us*
|
|
|
|
Stop the trace if the total sample is higher than the argument in microseconds.
|
|
If **-T** is set, it will also save the trace to the output.
|
|
|
|
**-T**, **--threshold** *us*
|
|
|
|
Specify the minimum delta between two time reads to be considered noise.
|
|
The default threshold is *5 us*.
|
|
|
|
**-t**, **--trace** \[*file*]
|
|
|
|
Save the stopped trace to [*file|osnoise_trace.txt*].
