Struct prometheus::Registry

pub struct Registry { /* fields omitted */ }

Registry registers Prometheus collectors, collects their metrics, and gathers them into MetricFamilies for exposition.

Methods

impl Registry

fn new() -> Registry

new creates a Registry.

fn register(&self, c: Box<Collector>) -> Result<()>

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.

fn unregister(&self, c: Box<Collector>) -> Result<()>

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.

fn gather(&self) -> Vec<MetricFamily>

gather calls the Collect method of the registered Collectors and then gathers the collected metrics into a lexicographically sorted slice of MetricFamily protobufs.
