DESCRIPTION =========== .. include:: common_timerlat_description.rst The *timerlat* tracer outputs information in two ways. It periodically prints the timer latency at the timer *IRQ* handler and the *Thread* handler. It also provides information for each noise via the **osnoise:** tracepoints. The **rtla timerlat top** mode displays a summary of the periodic output from the *timerlat* tracer. The **rtla hist hist** mode displays a histogram of each tracer event occurrence. For further details, please refer to the respective man page. MODES ===== **top** Prints the summary from *timerlat* tracer. **hist** Prints a histogram of timerlat samples. If no *MODE* is given, the top mode is called, passing the arguments. OPTIONS ======= **-h**, **--help** Display the help text. For other options, see the man page for the corresponding mode.
