Transport performance metrics.

Fields

RequestsTotal: u64

Total number of requests sent (including retries).

RequestsSuccessful: u64

Total number of successful requests (2xx/OK responses).

RequestsFailed: u64

Total number of failed requests (excludes timeouts/retries).

NotificationsSent: u64

Total number of notifications sent.

ConnectionsEstablished: u64

Total number of connections established (includes reconnections).

ConnectionFailures: u64

Total number of connection failures.

BytesSent: u64

Total bytes sent (compressed size if compression enabled).

BytesReceived: u64

Total bytes received (compressed size if compression enabled).

CircuitBreakerState: u32

Counter for circuit breaker state changes.

LatencyMillisecondsHistogram: Option<(u64, f64, f64)>

Histogram of request latencies in milliseconds (p50, p95, p99). Stored as (count, sum, sum of squares) for online variance calculation.

ActiveConnections: u32

Current active connections (gauge).

PendingRequests: u32

Current pending requests (gauge).

Implementations

impl TransportMetrics

pub fn New() -> Self

Creates a new, empty metrics container.

pub fn Reset(&mut self)

Resets all cumulative metrics to zero.

pub fn SuccessRate(&self) -> Option<f64>

Computes the success rate as a percentage (0-100).

pub fn AverageLatency(&self) -> Option<f64>

Computes the average request latency in milliseconds.

pub fn LatencyPercentile95(&self) -> Option<f64>

Computes the 95th percentile latency from the histogram.

pub fn RecordLatency(&mut self, LatencyMilliseconds: f64)

Records a request latency sample.

pub fn IncrementRequestSuccess(&mut self)

Increments the RequestsTotal and RequestsSuccessful counters.

pub fn IncrementRequestFailure(&mut self)

Increments the RequestsTotal and RequestsFailed counters.

pub fn SetCircuitBreakerState(&mut self, State: CircuitBreakerState)

Updates the circuit breaker state.
