8
9**-a**, **--auto** *us*
10
11 Set the automatic trace mode. This mode sets some commonly used options
12 while debugging the system. It is equivalent to use **-s** *us* **-T 1 -t**.
13
14**-p**, **--period** *us*
15
16 Set the *osnoise* tracer period in microseconds.
17
18**-r**, **--runtime** *us*
19
20 Set the *osnoise* tracer runtime in microseconds.
21
22**-s**, **--stop** *us*
23
24 Stop the trace if a single sample is higher than the argument in microseconds.
25 If **-T** is set, it will also save the trace to the output.
26
27**-S**, **--stop-total** *us*
28
29 Stop the trace if the total sample is higher than the argument in microseconds.
30 If **-T** is set, it will also save the trace to the output.
31
32**-T**, **--threshold** *us*
33
34 Specify the minimum delta between two time reads to be considered noise.
35 The default threshold is *5 us*.
36
37**-t**, **--trace** \[*file*]
38
39 Save the stopped trace to [*file|osnoise_trace.txt*].
