19The *osnoise* tracer outputs information in two ways. It periodically prints
20a summary of the noise of the operating system, including the counters of
21the occurrence of the source of interference. It also provides information
22for each noise via the **osnoise:** tracepoints. The **rtla osnoise top**
23mode displays information about the periodic summary from the *osnoise* tracer.
24The **rtla osnoise hist** mode displays information about the noise using
25the **osnoise:** tracepoints. For further details, please refer to the
26respective man page.
