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. 27 28MODES 29===== 30**top** 31 32 Prints the summary from osnoise tracer. 33 34**hist** 35 36 Prints a histogram of osnoise samples. 37 38If no MODE is given, the top mode is called, passing the arguments. 39 40OPTIONS 41======= 42 43**-h**, **--help** 44 45 Display the help text. 46 47For other options, see the man page for the corresponding mode. 48 49SEE ALSO 50======== 51**rtla-osnoise-top**\(1), **rtla-osnoise-hist**\(1) 52 53Osnoise tracer documentation: <https://www.kernel.org/doc/html/latest/trace/osnoise-tracer.html> 54 55AUTHOR 56====== 57Written by Daniel Bristot de Oliveira <bristot@kernel.org> 58 59.. include:: common_appendix.txt 60
