SYNOPSIS
|
|
========
|
|
**rtla osnoise** [*MODE*] ...
|
|
|
|
DESCRIPTION
|
|
===========
|
|
|
|
.. include:: common_osnoise_description.rst
|
|
|
|
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.
|
|
|
|
