[][src]Struct actix_web_metrics_mw::Metrics

#[must_use = "must be set up as a middleware for actix-web"]
pub struct Metrics { /* fields omitted */ }

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.

Methods

impl Metrics[src]

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

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

pub fn start(self)[src]
