A swift OpenTelemetry client
This package includes several libraries. The OpenTelemetryApi library includes protocols and no-op implementations that comprise the OpenTelemetry API following the specification. The OpenTelemetrySdk library is the reference implementation of the API.
Libraries that produce telemetry data should only depend on OpenTelemetryApi, and defer the choice of the SDK to the application developer. Applications may depend on OpenTelemetrySdk or another package that implements the API.
Please note that this library is currently in alpha, and shouldn't be used in production environments.
opentelemetry-swift is designed for Swift 5. To depend on the opentelemetry-swift package, you need to declare your dependency in your Package.swift:
.package(url: "https://github.com/open-telemetry/opentelemetry-swift", from: "0.4.0"),
and to your application/library target, add OpenTelemetryApi or OpenTelemetrySdkto your dependencies, e.g. like this:
.target(name: "ExampleTelemetryProducerApp", dependencies: ["OpenTelemetryApi"]),
or
.target(name: "ExampleApp", dependencies: ["OpenTelemetrySdk"]),
Currently Tracing, Metrics and Correlation Context API's and SDK are implemented, also OpenTracing shims, for compatibility with existing Opentracing code.
Implemented traces exporters: simple stdout, Jaeger, Zipkin, Datadog and OpenTelemetry collector
Implemented metrics exporters: Prometheus
The package includes some example projects with basic functionality:
Logging Tracer- Simple api implementation of a Tracer that logs every api callSimple Exporter- Shows the Jaeger an Stdout exporters in action using a MultiSpanExporter. Can be easily modified for other exportersPrometheus Sample- Shows the Prometheus exporter reporting metrics to a Prometheus instance
