Runtime metrics for ThreadPool ThreadCount is not implemented as UpDownCounter #112077
Description
In the documentation it is mentioned that the ThreadPool ThreadCount metics is of type UpDownCounter
But it looks like it is implemented as a Monotonic counter as it uses CreateObservableCounter instead of CreateObservableUpDownCounter
Shouldn't it be an UpDownCounter or a Gauge if it is The number of thread pool threads that currently exist?
