Struct PrometheusConfiguration 

pub struct PrometheusConfiguration { /* private fields */ }

Prometheus destination.

Exposes a Prometheus scrape endpoint that emits metrics in the Prometheus exposition format.

Limits

• Number of contexts (unique series) is limited to 10,000.
• Maximum size of scrape payload response is ~1MiB.

Missing

• no support for expiring metrics (which we don’t really need because the only use for this destination at the moment is internal metrics, which aren’t dynamic since we don’t use dynamic tags or have dynamic topology support, but… you know, we’ll eventually need this)
• full support for distributions (we can’t convert a distribution to an aggregated histogram, and native histogram support is still too fresh for most clients, so we simply expose aggregated summaries as a stopgap)

Implementations

impl PrometheusConfiguration

pub fn from_configuration( config: &GenericConfiguration, ) -> Result<Self, GenericError>

Creates a new PrometheusConfiguration from the given configuration.

pub fn listen_address(&self) -> &ListenAddress

Returns the listen address for the Prometheus scrape endpoint.
