		kHealthId	id,
		k32u	instance
	)

Notes that a stat has gone offline.

This method can optionally be called to note that a statistic is not currenty available. For non-restoring stats, this will cause any future logged values to be reported as nulls until the stat is registered again.

This method is intended to be fast; no file I/O is performed.

This method is thread-safe.

Parameters

log	Health log object.
id	Health stat id.
instance	Health stat instance.

Returns

Operation status.
