This is the JavaScript version of OpenTelemetry, a framework for collecting traces, metrics and logs from applications.
This project is currently in Alpha stage. Its APIs can change at any time and it is not intended to be used in production scenarios!
To get started, see @opentelemetry/tracing for an SDK that supports creating traces through manual instrumentation or @opentelemetry/node which provides auto-instrumentation for Node.js applications.
OpenTelemetry JS is under active development. This release isn't guaranteed to conform to a specific version of the specification, and future releases will not attempt to maintain backwards compatibility with the alpha release.
The alpha release includes:
- Tracing API
- Tracing SDK (Node and Web)
- Metrics API
- Jaeger Trace Exporter
- Zipkin Trace Exporter
- OpenTracing Bridge
- HTTP, GRPC Instrumentations
Future release targets include:
| Component | Version | Target Date |
|---|---|---|
| Metrics SDK | v0.2.0 | October 28 2019 |
| Prometheus Metrics Exporter | v0.2.0 | October 28 2019 |
| OpenCensus Bridge | v0.2.0 | tbd |
We'd love your help!. Use tags up-for-grabs and good first issue to get started with the project. Follow CONTRIBUTING guide to report issues or submit a proposal.
We have a weekly SIG meeting! See the community page for meeting details and notes.
| Package | Description |
|---|---|
| @opentelemetry/types | This package provides TypeScript interfaces and enums for the OpenTelemetry core trace and metrics model. It is intended for use both on the server and in the browser. |
| @opentelemetry/core | This package provides default and no-op implementations of the OpenTelemetry types for trace and metrics. It's intended for use both on the server and in the browser. |
| Package | Description |
|---|---|
| @opentelemetry/tracing | This module provides a full control over instrumentation and span creation. It doesn't load async_hooks or any instrumentation plugin by default. It is intended for use both on the server and in the browser. |
| @opentelemetry/metrics | This module provides instruments and meters for reporting of time series data. |
| @opentelemetry/node | This module provides automatic tracing for Node.js applications. It is intended for use on the server only. |
| @opentelemetry/web | This module provides automated instrumentation and tracing for Web applications. It is intended for use in the browser only. |
OpenTelemetry is vendor-agnostic and can upload data to any backend with various exporter implementations. Even though, OpenTelemetry provides support for many backends, vendors/users can also implement their own exporters for proprietary and unofficially supported backends. Currently, OpenTelemetry supports:
OpenTelemetry can collect tracing data automatically using plugins. Vendors/Users can also create and use their own. Currently, OpenTelemetry supports automatic tracing for:
- @opentelemetry/plugin-http
- @opentelemetry/plugin-grpc
- @opentelemetry/plugin-https
- @opentelemetry/plugin-postgres - WIP
To request automatic tracing support for a module not on this list, please file an issue. Alternatively, you can write a plugin yourself.
| Package | Description |
|---|---|
| @opentelemetry/shim-opentracing | OpenTracing shim allows existing OpenTracing instrumentation to report to OpenTelemetry |
