| |
| 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. |
