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.
