Users scraping this endpoint with the Prometheus receiver will see these renamed labels in resource and datapoint attributes. As a workaround, add the following `metric_relabel_configs` to your scrape config in prometheus receiver: ```yaml metric_relabel_configs: - source_labels: [service_name] target_label: service.name - source_labels: [service_instance_id] target_label: service.instance.id - source_labels: [service_version] target_label: service.version - regex: service_name|service_instance_id|service_version action: labeldrop ``` See [#​14814](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14814) for details and updates. ##### 🛑 Breaking changes 🛑 - `all`: Change metric units to be singular to match OTel specification, e.g. `{requests}` -> `{request}` ([#​14753](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14753)) ##### 💡 Enhancements 💡 - `cmd/mdatagen`: Add deprecated\_type field to allow specifying an alias for component types. ([#​14718](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14718)) - `cmd/mdatagen`: Generate entity-scoped MetricsBuilder API that enforces entity-metric associations at compile time ([#​14659](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14659)) - `cmd/mdatagen`: Skip generating reaggregation config options for metrics that have no aggregatable attributes. ([#​14689](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14689)) - `pkg/service`: The internal status reporter no longer drops repeated Ok and RecoverableError statuses ([#​14282](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14282)) Status events can now carry metadata and there's value in allowing them to be emitted despite the status value itself not changing. ##### 🧰 Bug fixes 🧰 - `cmd/builder`: Add `.exe` to output binary names when building for Windows targets. ([#​12591](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/12591)) - `exporter/debug`: Add printing of metric metadata in detailed verbosity. ([#​14667](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14667)) - `exporter/otlp_grpc`: Prevent nil pointer panic when push methods are called before the OTLP exporter initializes its gRPC clients. ([#​14663](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14663)) When the sending queue and retry are disabled, calling ConsumeTraces, ConsumeMetrics, ConsumeLogs, or ConsumeProfiles before the OTLP exporter initializes its gRPC clients could cause a nil pointer dereference panic. The push methods now return an error instead of panicking. - `exporter/otlp_http`: Show the actual destination URL in error messages when request URL is modified by middleware. ([#​14673](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14673)) Unwraps the `*url.Error` returned by `http.Client.Do()` to prevent misleading error logs when a middleware extension dynamically updates the endpoint. - `pdata/pprofile`: Switch the dictionary of dictionary tables entries only once when merging profiles ([#​14709](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14709)) For dictionary table data, we used to switch their dictionaries when doing the switch for the data that uses them. However, when an entry is associated with multiple other data (several samples can use the same stack), we would have been switching the dictionaries of the entry multiple times. We now switch dictionaries for dictionary table data only once, before switching the resource profiles. <!-- previous-version --> </details> --- ### Configuration 📅 **Schedule**: Branch creation - At any time (no schedule defined), Automerge - At any time (no schedule defined). 🚦 **Automerge**: Disabled by config.

OpenTelemetry-Go
OpenTelemetry-Go is the Go implementation of OpenTelemetry. It provides a set of APIs to directly measure performance and behavior of your software and send this data to observability platforms.
Project Status
| Signal | Status |
|---|---|
| Traces | Stable |
| Metrics | Stable |
| Logs | Beta1 |
Progress and status specific to this repository is tracked in our project boards and milestones.
Project versioning information and stability guarantees can be found in the versioning documentation.
Compatibility
OpenTelemetry-Go ensures compatibility with the current supported versions of the Go language:
Each major Go release is supported until there are two newer major releases. For example, Go 1.5 was supported until the Go 1.7 release, and Go 1.6 was supported until the Go 1.8 release.
For versions of Go that are no longer supported upstream, opentelemetry-go will stop ensuring compatibility with these versions in the following manner:
- A minor release of opentelemetry-go will be made to add support for the new supported release of Go.
- The following minor release of opentelemetry-go will remove compatibility testing for the oldest (now archived upstream) version of Go. This, and future, releases of opentelemetry-go may include features only supported by the currently supported versions of Go.
Currently, this project supports the following environments.
| OS | Go Version | Architecture |
|---|---|---|
| Ubuntu | 1.26 | amd64 |
| Ubuntu | 1.25 | amd64 |
| Ubuntu | 1.26 | 386 |
| Ubuntu | 1.25 | 386 |
| Ubuntu | 1.26 | arm64 |

| Windows | 1.26 | amd64 |
| Windows | 1.25 | amd64 |

While this project should work for other systems, no compatibility guarantees are made for those systems currently.
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 otel package. The 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.
All officially supported exporters for the OpenTelemetry project are contained in the exporters directory.
