Struct PrometheusObserver 

pub struct PrometheusObserver { /* private fields */ }

Publishes DialCache diagnostics to Prometheus collectors.

Clones share the collectors; hand one observer to every instance that exports to the same registry.

Implementations

impl PrometheusObserver

pub fn new( registry: &Registry, prefix: &str, ) -> Result<PrometheusObserver, PrometheusError>

Register the DialCache collectors named <prefix>dialcache_* on registry. Registering the same names twice on one registry is a PrometheusError::Conflict: clone the observer instead.

pub fn schemas(&self) -> Vec<CollectorSchema>

The wire schemas of this observer’s collectors.
