realtime runtime code throughput margin monitoring

[Ether]

I'm wondering how many teams add runtime throughput and scheduling monitoring in each thread (or parallel loop) of their practice or even competition deployed code.

Something like the following

* thread start *
t0=system_microseconds();
if (t0-t1)>TBD1 err1++; //scheduling monitor
t1=t0;
* put thread code here *
if (system_microseconds()-t0)>TBD2 err2++; //thread throughput margin monitor
* thread end *

"err1" and 'err2" could be displayed on the dashboard for each thread.
