:mrdocs:

If the optionally specified `manager` is not 0, return `manager`; otherwise return the address of the default metrics manager instance, or 0 if the default metrics manager instance has not yet been created or has already been destroyed. Note that this operation is logically equivalent to `manager ? manager : instance()`.
