It periodically20prints the timer latency at the timer *IRQ* handler and the *Thread* handler.21It also provides information for each noise via the **osnoise:** tracepoints.22The **rtla timerlat top** mode displays a summary of the periodic output23from the *timerlat* tracer. The **rtla hist hist** mode displays a histogram24of each tracer event occurrence.
