The Go [OpenTelemetry](https://opentelemetry.io/) 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](https://github.com/orgs/open-telemetry/projects/5). 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](https://github.com/open-telemetry/opentelemetry-go/projects)
|
|
and

## Getting Started
|
|
|
|
You can find a getting started guide on [opentelemetry.io](https://opentelemetry.io/docs/go/getting-started/).
|
|
|
|
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](https://github.com/open-telemetry/opentelemetry-go-contrib/tree/main/instrumentation).
|
|
|
|
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](https://pkg.go.dev/go.opentelemetry.io/otel/api)
|
|
package. The included [examples](./example/) 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](./exporters/) and in the
|
|
companion [contrib
|
|
repository](https://github.com/open-telemetry/opentelemetry-go-contrib/tree/main/exporters/metric).
|
|
Additionally, there are many vendor specific or 3rd party exporters for
|
|
OpenTelemetry. These exporters are broken down by
|
|
[trace](https://pkg.go.dev/go.opentelemetry.io/otel/sdk/export/trace?tab=importedby)
|
|
and
|
|
[metric](https://pkg.go.dev/go.opentelemetry.io/otel/sdk/export/metric?tab=importedby)
|
|
support.
