Struct TelemetryConfig 

pub struct TelemetryConfig {
    pub service_name: String,
    pub service_version: String,
    pub environment: String,
    pub otlp_traces_endpoint: Option<String>,
    pub otlp_logs_endpoint: Option<String>,
    pub otlp_metrics_endpoint: Option<String>,
    pub log_to_stderr: bool,
    pub use_metrics_interval: Option<Duration>,
    pub metrics_flush_interval: Option<Duration>,
    pub sampling_rate: Option<f64>,
    pub backpressure_strategy: BackpressureStrategy,
    pub resource_attributes: Vec<(String, String)>,
}

Configuration for the telemetry stack.

Construct with struct literal + ..Default::default() to be forward-compatible when new fields are added:

let config = TelemetryConfig {
    service_name: "my-service".into(),
    service_version: "0.1.0".into(),
    otlp_traces_endpoint: Some("http://collector:4318".into()),
    ..Default::default()
};

Fields

service_name: String

service_version: String

environment: String

otlp_traces_endpoint: Option<String>

OTLP HTTP endpoint for traces (e.g. “http://jaeger:4318”). If None, trace export is disabled.

otlp_logs_endpoint: Option<String>

OTLP HTTP endpoint for logs (e.g. “http://vector:4318”). If None, log export is disabled. Can differ from traces endpoint.

otlp_metrics_endpoint: Option<String>

OTLP HTTP endpoint for metrics (e.g. “http://vector:4318”). If None, metrics export is disabled.

log_to_stderr: bool

Whether to emit JSON-formatted logs to stderr.

use_metrics_interval: Option<Duration>

Polling interval for USE metrics (cpu, memory) from /proc/self/stat. If None, USE metrics collection is disabled. Only active on Linux; no-op on other platforms.

metrics_flush_interval: Option<Duration>

How often to flush aggregated metrics to the OTLP endpoint. Defaults to 10 seconds if None.

sampling_rate: Option<f64>

Probabilistic trace sampling rate: 1.0 = export all traces, 0.01 = export 1%. Sampling is deterministic based on trace_id, so the same trace always gets the same decision across services. Metrics are never sampled. Defaults to 1.0 (no sampling) if None.

backpressure_strategy: BackpressureStrategy

What to do when the export channel is full. Defaults to BackpressureStrategy::Drop.

resource_attributes: Vec<(String, String)>

Custom OTel resource attributes appended after the standard three (service.name, service.version, deployment.environment).
