Struct Metrics 

pub struct Metrics { /* private fields */ }

By default two metrics are tracked (this assumes the namespace actix_web_prom):

This uses the generic metrics crate which allows you to :

• Push histograms, gauges and counters to a receiver
• Register an exporter that will periodically drain the latest metrics

Available exporters :

• Statsd : supports the generic mode, or the dogstats mode, in dogstats mode the labels will be sent as tags in the metric name

Default metrics :

• http_requests_total (labels: endpoint, method, status): request counter for each endpoint and method.

• http_requests_duration (labels: endpoint, method, status): histogram of request durations for each endpoint.

Implementations

impl Metrics

pub fn new(path: &str, namespace: &str, labels: Vec<(&str, &str)>) -> Self

Create a new Metrics. You set the namespace and the metrics endpoint through here.

pub fn start(self)

Trait Implementations

impl Clone for Metrics

fn clone(&self) -> Metrics

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<S, B> Transform<S> for Metrics

where S: Service<Request = ServiceRequest, Response = ServiceResponse<B>, Error = Error>, S::Future: 'static, B: MessageBody,

type Request = ServiceRequest

Requests handled by the service.

type Response = ServiceResponse<StreamLog<B>>

Responses given by the service.

type Error = Error

Errors produced by the service.

type InitError = ()

Errors produced while building a transform service.

type Transform = MetricsMiddleware<S>

The TransformService value created by this factory

type Future = Ready<Result<<Metrics as Transform<S>>::Transform, <Metrics as Transform<S>>::InitError>>

The future response value.

fn new_transform(&self, service: S) -> Self::Future

Creates and returns a new Transform component, asynchronously

fn map_init_err<F, E>(self, f: F) -> TransformMapInitErr<Self, S, F, E>

where Self: Sized, F: Fn(Self::InitError) -> E + Clone,

Map this transforms’s factory error to a different error, returning a new transform service factory.
