* Move grpc stuff to separate package * Drop duplicated retryable status code * Set default port to 4317 This is what the specification says for both gRPC and HTTP. * Document gRPC option type * Add an HTTP protocol driver for OTLP exporter Currently it supports only binary protobuf payloads. * Move end to end test to a separate package It also adds some common code mock collectors can use. This will be useful for testing the HTTP driver. * Move export data creators to otlptest It also extends the one record checkpointer a bit. This will be useful for testing the HTTP driver. * Add an HTTP mock collector and tests for HTTP driver * Update changelog * Do not depend on DefaultTransport We create our own instance of the transport, which is based on golang's DefaultTransport. That way we sidestep the issue of the DefaultTransport being modified/overwritten. We won't have any panics at init. The cost of it is to keep the transport fields in sync with DefaultTransport. * Read the whole response body before closing it This may help with connection reuse. * Change options to conform to our style guide * Add jitter to backoff time * Test TLS option * Test extra headers * Fix a comment * Increase coverage * Add a source of the backoff strategy |

OpenTelemetry-Go
The Go OpenTelemetry implementation.
Project Status
Warning: this project is currently in a pre-GA phase. Backwards incompatible changes may be introduced in subsequent minor version releases as we work to track the evolving OpenTelemetry specification and user feedback.
Our progress towards a GA release candidate is tracked in this project board. This release candidate will follow semantic versioning and will be released with a major version greater than zero.
Progress and status specific to this repository is tracked in our local project boards and milestones.
Project versioning information and stability guarantees can be found in the versioning documentation.
Getting Started
You can find a getting started guide on opentelemetry.io.
OpenTelemetry's goal is to provide a single set of APIs to capture distributed traces and metrics from your application and send them to an observability platform. This project allows you to do just that for applications written in Go. There are two steps to this process: instrument your application, and configure an exporter.
Instrumentation
To start capturing distributed traces and metric events from your application it first needs to be instrumented. The easiest way to do this is by using an instrumentation library for your code. Be sure to check out the officially supported instrumentation libraries.
If you need to extend the telemetry an instrumentation library provides or want to build your own instrumentation for your application directly you will need to use the go.opentelemetry.io/otel/api package. The included examples are a good way to see some practical uses of this process.
Export
Now that your application is instrumented to collect telemetry, it needs an export pipeline to send that telemetry to an observability platform.
You can find officially supported exporters here and in the companion contrib repository. Additionally, there are many vendor specific or 3rd party exporters for OpenTelemetry. These exporters are broken down by trace and metric support.
