Struct OtlpConfig 

pub struct OtlpConfig {
    pub endpoint: String,
    pub protocol: OtlpProtocol,
    pub sample_ratio: f64,
    pub service_name: String,
    pub service_version: String,
    pub service_instance_id: String,
    pub timeout: Time,
    pub heartbeat_interval: Option<Time>,
}

Resolved OTLP configuration.

OtlpConfig::from_env builds this configuration. Ok(None) from that constructor means that OTLP is disabled and that this crate builds no exporter.

Fields

endpoint: String

protocol: OtlpProtocol

sample_ratio: f64

Head sampling ratio in [0.0, 1.0]. A parent-based sampler wraps this ratio, so child spans keep an upstream sampling decision.

service_name: String

service_version: String

service_instance_id: String

timeout: Time

heartbeat_interval: Option<Time>

Implementations

impl OtlpConfig

pub fn from_env( get: impl Fn(&str) -> Option<String>, service_instance_id: &str, service_version: &str, default_service_name: &str, ) -> Result<Option<Self>, TelemetryError>

Resolve OTLP config from the environment.

get is the environment lookup. The caller injects it, so this function is pure and easy to test. service_instance_id is the service instance id, for example the broker node id. service_version is the crate version. default_service_name is the fallback name for when OTEL_SERVICE_NAME is not set.

Returns Ok(None) when OTLP is disabled. OTLP is disabled when nothing turned it on, or when OTEL_SDK_DISABLED turned it off.

Errors

Returns an error when a custom Krabka duration is malformed.
