		typing.Optional[str]	subpath = None,
		typing.Optional[typing.Dict]	add_labels = None,
		*	,
		typing.Optional[float]	default = None )

Returns a single metric value at the specified path, prepending the path provided at construction.

If a dict of labels is provided, does en exact match of labels, prepending the labels provided at construction.

Parameters

subpath	Suffix of the metric path; the path provided at construction is prepended
add_labels	Labels that the metric must have in addition to the labels provided at construction
default	An optional default value in case the metric is missing

Exceptions

AssertionError

if not one metric by path
