Struct ApiMetrics 

pub struct ApiMetrics { /* private fields */ }

Thread-safe metrics collector for API endpoints.

Tracks per-path request counts, response times, error counts, and active request gauge.

Example

use auth_framework::api::metrics::ApiMetrics;
use std::time::Duration;
use axum::http::StatusCode;

let m = ApiMetrics::new();
m.record_request("/login");
m.record_response("/login", Duration::from_millis(5), StatusCode::OK);

let snap = m.get_metrics();
assert_eq!(snap.total_requests, 1);

Implementations

impl ApiMetrics

pub fn new() -> Self

Create a new, empty metrics collector.

Example

use auth_framework::api::metrics::ApiMetrics;
let m = ApiMetrics::new();
assert_eq!(m.get_metrics().total_requests, 0);

pub fn record_request(&self, path: &str)

Record an incoming request for path.

Increments the request counter and the active-requests gauge.

Example

use auth_framework::api::metrics::ApiMetrics;
let m = ApiMetrics::new();
m.record_request("/health");

pub fn record_response( &self, path: &str, duration: Duration, status: StatusCode, )

Record a completed response for path.

Stores the response duration, increments error counters for 4xx/5xx status codes, and decrements the active-requests gauge.

Example

use auth_framework::api::metrics::ApiMetrics;
use std::time::Duration;
use axum::http::StatusCode;

let m = ApiMetrics::new();
m.record_request("/api");
m.record_response("/api", Duration::from_millis(12), StatusCode::OK);

pub fn get_metrics(&self) -> MetricsSnapshot

Snapshot all collected metrics.

Returns a MetricsSnapshot with uptime, totals, and per-endpoint statistics including average, p95, and p99 response times.

Example

use auth_framework::api::metrics::ApiMetrics;

let m = ApiMetrics::new();
let snap = m.get_metrics();
assert_eq!(snap.total_requests, 0);

pub fn reset(&self)

Reset all counters and timers.

Clears request counts, response times, error counts, and resets the uptime clock.

Example

use auth_framework::api::metrics::ApiMetrics;
use std::time::Duration;
use axum::http::StatusCode;

let m = ApiMetrics::new();
m.record_request("/x");
m.record_response("/x", Duration::from_millis(1), StatusCode::OK);
m.reset();
assert_eq!(m.get_metrics().total_requests, 0);
