1 The **rtla timerlat** tool is an interface for the *timerlat* tracer. The 2 *timerlat* tracer dispatches a kernel thread per-cpu. These threads 3 set a periodic timer to wake themselves up and go back to sleep. After 4 the wakeup, they collect and generate useful information for the 5 debugging of operating system timer latency. 6 7 The *timerlat* tracer outputs information in two ways. It periodically 8 prints the timer latency at the timer *IRQ* handler and the *Thread* 9 handler. It also enable the trace of the most relevant information via 10 **osnoise:** tracepoints.
