Crate apollo_opentelemetry 

OpenTelemetry crate for Apollo platform.

This crate provides a standard way to configure and use OpenTelemetry.

Getting Started

Create telemetry from configuration:

use apollo_configuration::parse_yaml;
use apollo_opentelemetry::{OpenTelemetryConfig, Telemetry};

let yaml = r#"
  tracer_provider:
    processors:
      - batch:
          exporter:
            otlp_http:
              endpoint: http://localhost:4318
"#;
let config: OpenTelemetryConfig = parse_yaml(yaml, &Default::default())?;
let telemetry = Telemetry::new(config)?;

Or use the builder for more control:

use apollo_configuration::parse_yaml;
use apollo_opentelemetry::{OpenTelemetryConfig, Telemetry};

let yaml = r#"
  tracer_provider:
    processors:
      - batch:
          exporter:
            otlp_http:
              endpoint: http://localhost:4318
"#;
let config: OpenTelemetryConfig = parse_yaml(yaml, &Default::default())?;
let telemetry = Telemetry::builder(config)
    .with_global_tracer_provider()
    .with_global_meter_provider()
    .build()?;
