pub struct Registry { /* fields omitted */ }
A struct for registering Prometheus collectors, collecting their metrics, and gathering
them into MetricFamilies
for exposition.
register
registers a new Collector
to be included in metrics
collection. It returns an error if the descriptors provided by the
Collector
are invalid or if they — in combination with descriptors of
already registered Collectors — do not fulfill the consistency and
uniqueness criteria described in the documentation of Desc
.
If the provided Collector
is equal to a Collector
already registered
(which includes the case of re-registering the same Collector
), the
AlreadyReg error returns.
unregister
unregisters the Collector
that equals the Collector
passed
in as an argument. (Two Collectors are considered equal if their
Describe method yields the same set of descriptors.) The function
returns error when the Collector
is not registered.
gather
calls the Collect method of the registered Collectors and then
gathers the collected metrics into a lexicographically sorted slice
of MetricFamily protobufs.
