Implementations

impl JanusMetrics

pub fn new() -> Self

Create new metrics instance

pub fn record_signal( &self, module: &str, signal_type: &str, symbol: &str, confidence: f64, )

Record a signal generation

pub fn record_module_health( &self, module: &str, healthy: bool, uptime_seconds: f64, )

Record module health

pub fn record_http_request( &self, method: &str, path: &str, status: u16, duration_secs: f64, )

Record HTTP request

pub fn record_supervisor_spawn(&self)

Record a service spawn event (counter only — the active_services gauge is managed by SupervisorMetrics).

pub fn record_supervisor_restart(&self)

Record a service restart event.

pub fn record_supervisor_termination(&self)

Record a service termination event (counter only — the active_services gauge is managed by SupervisorMetrics).

pub fn record_supervisor_circuit_breaker_trip(&self)

Record a circuit breaker trip event.

pub fn record_supervisor_service_uptime(&self, service: &str, uptime_secs: f64)

Record a service’s cumulative uptime when it terminates.

pub fn encode(&self) -> String

Get all metrics as text (for /metrics endpoint)

Trait Implementations

impl Default for JanusMetrics

fn default() -> Self

Returns the “default value” for a type.
