0018
0019 The *osnoise* tracer outputs information in two ways. It periodically prints
0020 a summary of the noise of the operating system, including the counters of
0021 the occurrence of the source of interference. It also provides information
0022 for each noise via the **osnoise:** tracepoints. The **rtla osnoise top**
0023 mode displays information about the periodic summary from the *osnoise* tracer.
0024 The **rtla osnoise hist** mode displays information about the noise using
0025 the **osnoise:** tracepoints. For further details, please refer to the
0026 respective man page.
