This can be considered a metric that informs you how much CPU
resources are being consumed by your loop, in the best case scenario
where there is only your process, this metric
>>> For this proposal [4], POC, I've preferred make a reduced list of events:
>>>
>>> * `loop_start` : Executed when the loop starts for the first time.
>>> * `tick_start` : Executed when a new loop tick is started.
>>> * `io_start` : Executed when a new IO process starts.
>>> * `io_end` : Executed
