Per-entity authentication metrics.

Tracks auth attempts for a single entity (IP) against auth endpoints.

Fields

entity_id: String

Entity identifier (IP address)

endpoint: String

Endpoint being tracked (e.g., “/api/login”)

failures: u32

Failed auth attempts in current window

successes: u32

Successful auth attempts in current window

window_start: u64

Window start timestamp (ms since epoch)

last_attempt: u64

Last attempt timestamp (ms since epoch)

total_failures: u64

Total failed attempts (lifetime)

total_successes: u64

Total successful attempts (lifetime)

hourly_failures: [u32; 24]

Hourly failure buckets (24 hours)

current_hour_index: u8

Current hour index (0-23)

last_hour_rotation: u64

Last hour rotation timestamp

Implementations

impl AuthMetrics

pub fn new(entity_id: String, endpoint: String, now: u64) -> Self

Create new auth metrics for an entity/endpoint pair.

pub fn record_failure(&mut self, now: u64)

Record a failed attempt.

pub fn record_success(&mut self, now: u64)

Record a successful attempt.

pub fn reset_window(&mut self, now: u64)

Reset sliding window.

pub fn detect_low_and_slow( &self, min_hours: usize, min_failures_per_hour: u32, ) -> bool

Detect low-and-slow pattern (consistent failures over hours).

Returns true if failures are spread evenly across multiple hours.

pub fn failure_rate(&self, now: u64) -> f64

Get failure rate (failures per second in current window).
