how to properly log and understand CPU load by a task on APM ? (ArduPlane)

[André Kjellstrup]

I am adding code called by AP_Scheduler. 
How can I check how much it influence the overall performance of APM ?

ok, so far, I've found only this : http://diydrones.com/forum/topics/long-time-consuming-process-in-main-loop?commentId=705844%3AComment%3A1497774

Andre,

 

      There’s a load value that is visible in the mission planner.  This value comes from the scheduler.load_average().

 

      You can also turn on the SCHEDULE_DEBUG parameter and it will dump out information about missed tasks to the console.  In arducopter you’ll see a lot of warnings though even in master with none of your changes included.

 

     The PM message also has information about how many main loops took longer than 10500 micro seconds (i.e. 10.5 milliseconds).
