OpenTelemetry - distributed tracing and stats collection framework
About this project
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!
Quick start
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.
Release Schedule
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 v0.2 alpha release includes:
- Tracing API
- Tracing SDK (Node and Web)
- Metrics API
- Jaeger Trace Exporter
- Zipkin Trace Exporter
- OpenTracing Bridge
- HTTP, GRPC, DNS Instrumentations
- Document Load for web
- Metrics SDK (
CounterandGaugesupport) - Export work is underway.
See the project milestones for details on upcoming releases. The dates and features described here are estimates, and subject to change.
Future release targets include:
| Component | Version | Target Date |
|---|---|---|
| Prometheus Metrics Exporter | Alpha v0.3 | November 15 2019 |
| mongodb Instrumentation | Alpha v0.3 | November 15 2019 |
| postgres Instrumentation | Alpha v0.3 | November 15 2019 |
| OpenCensus Bridge | Alpha v0.3 | tbd |

Packages
API
| 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. |
Implementation / SDKs
| 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/base | This package provides base code for the SDK packages (tracing and metrics). |
Exporters
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:
Trace Exporters
Metric Exporters
Plugins
OpenTelemetry can collect tracing data automatically using plugins. Vendors/Users can also create and use their own. Currently, OpenTelemetry supports automatic tracing for:
Node Plugins
- @opentelemetry/plugin-http
- @opentelemetry/plugin-grpc
- @opentelemetry/plugin-https
- @opentelemetry/plugin-dns
- @opentelemetry/plugin-mongodb - WIP
- @opentelemetry/plugin-postgres - WIP
- @opentelemetry/plugin-redis - WIP
- @opentelemetry/plugin-mysql - WIP
Web Plugins
To request automatic tracing support for a module not on this list, please file an issue. Alternatively, you can write a plugin yourself.
Shims
| Package | Description |
|---|---|
| @opentelemetry/shim-opentracing | OpenTracing shim allows existing OpenTracing instrumentation to report to OpenTelemetry |
