* Add compatibility tests to CI * Increase timeout to 60s Some of the aggregator tests are running just over 30 seconds when testing on Windows. Bump this to allow for it. * Remove cache setup jobs Having a unified job setup the cache when none exists so packages are only downloaded once is ideal, but these steps are taking too long. In some situations they are doubling the run time. Remove them and prefer to have multiple downloads when dependencies change. * Add changes to changelog * Remove mod-download target from Makefile Unused now that the cache jobs are removed. * Add compatibility testing table to changelog * Add change about precommit to changelog * Update README * Correct examples target in lint job

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
|
|

## 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.
