Best would be to have it enabled, but if you believe we could get a very high 
number of events, it must be disabled or emitted at a lower frequency.

Typically, statistical events are emitted as periodic events, so users can set 
the period, e.g. 10 s, but that would require synchronization, which could also 
create issues.

The control parameter must be in sync with the element value.
**gc-enabled-normal** is the default mode, which means it will be true. 

**gc-enabled-high**, **gc-enabled-detailed** and **gc-enabled-all** are false 
by default. It would be good if you could provide some ballpark figures on the 
number of events in a worst-case scenario, so we can determine what GC level is 
appropriate.
