19 The *osnoise* tracer outputs information in two ways. It periodically prints
20 a summary of the noise of the operating system, including the counters of
21 the occurrence of the source of interference. It also provides information
22 for each noise via the **osnoise:** tracepoints. The **rtla osnoise top**
23 mode displays information about the periodic summary from the *osnoise* tracer.
24 The **rtla osnoise hist** mode displays information about the noise using
25 the **osnoise:** tracepoints. For further details, please refer to the
32 Prints the summary from osnoise tracer.
