A metrics exporter over OpenTelemetry

The metrics-exporter-opentelemetry crate is a metrics exporter over OpenTelemetry's metrics API.

Warnings

• The crate doesn't support the following methods from metrics:

  • Counter::absolute - OpenTelemetry doesn't keep track of the value inside of a counter.

  • Gauge::increment, Gauge::decrement - OpenTelemetry doesn't keep track of the value inside of a gauge.

  • Histogram::record_many - OpenTelemetry doesn't support recording multiple histogram points.

• The crate provide no-op implementations of the metrics::Recorder::describe_* as we can't modify a constructed counter/gauge/histogram from metrics::Recorder::register_*. The SDK keeps track of it but is internal and isn't able to be accessed.

Usage

// Cargo.toml:
//
// [dependencies]
// metrics = "^0"
// metrics-exporter-opentelemetry = "^0"

use metrics_exporter_opentelemetry::Recorder;

fn main() {
    // Install a global `metrics` recorder
    let _ = Recorder::builder("my-app")
        .install_global()
        .unwrap();

    let counter = metrics::counter!("hello.world");
    counter.increment(1);
}
