|
|
The *osnoise* tracer outputs information in two ways. It periodically prints |
|
a summary of the noise of the operating system, including the counters of |
|
the occurrence of the source of interference. It also provides information |
|
for each noise via the **osnoise:** tracepoints. The **rtla osnoise top** |
|
mode displays information about the periodic summary from the *osnoise* tracer. |
|
The **rtla osnoise hist** mode displays information about the noise using |
|
the **osnoise:** tracepoints. For further details, please refer to the |
|
respective man page. |
