Telemetry

Telemetry is a module that provides functionality for collecting and reporting OpenTelemetry-based metrics.

Omnia OpenTelemetry

OpenTelemetry tracing and metrics integration for the Omnia runtime. This crate initializes tracing-subscriber, OTLP span exporters, and metric readers with retry logic so that host runtimes report telemetry out-of-the-box.

Note: This is a host-side library (not compiled for wasm32). It is called internally by omnia::create() during runtime startup. Most users do not need to depend on this crate directly.

Usage

use omnia_otel::Telemetry;

// Minimal -- uses RUST_LOG for filtering, no OTLP export
Telemetry::new("my-service").build()?;

// With OTLP export to a collector
Telemetry::new("my-service")
    .endpoint("http://localhost:4317")
    .build()?;

The OTEL_GRPC_URL environment variable is also respected if no explicit endpoint is set.
