[−][src]Struct actix_web_metrics_mw::Metrics
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

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.
