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 26 respective man page. 27 28 MODES 29 ===== 30 **top** 31 32 Prints the summary from osnoise tracer. 33 34 **hist** 35 36 Prints a histogram of osnoise samples. 37 38 If no MODE is given, the top mode is called, passing the arguments. 39 40 OPTIONS 41 ======= 42 43 **-h**, **--help** 44 45 Display the help text. 46 47 For other options, see the man page for the corresponding mode. 48 49 SEE ALSO 50 ======== 51 **rtla-osnoise-top**\(1), **rtla-osnoise-hist**\(1) 52 53 Osnoise tracer documentation: <https://www.kernel.org/doc/html/latest/trace/osnoise-tracer.html> 54 55 AUTHOR 56 ====== 57 Written by Daniel Bristot de Oliveira <bristot@kernel.org> 58 59 .. include:: common_appendix.rst
