This project provides an automatic solution for Golang applications that want to leverage OpenTelemetry to enable effective observability. No code changes are required in the target application, the instrumentation is done at compile time. Simply adding otel prefix to go build to get started 🚀

Installation

Install via Bash

For Linux and MacOS users, install the tool by running the following command

$ sudo curl -fsSL https://cdn.jsdelivr.net/gh/alibaba/opentelemetry-go-auto-instrumentation@main/install.sh | sudo bash

It will be installed in /usr/local/bin/otel by default.

Precompiled Binary

Please download the latest precompiled release version from the Release page.

Build From Source

Checkout source code and build the tool by running one of following commands:

$ make         # build only
$ make install # build and install

Getting Started

Check the version by running:

$ otel version

The configuration for the tool can be set by the following command:

$ otel set -verbose                          # print verbose logs
$ otel set -debug                            # enable debug mode
$ otel set -debug -verbose -rule=custom.json # set multiple configs
$ otel set -disabledefault -rule=custom.json # disable default rules, use custom rules only
$ otel set -rule=custom.json                 # use default and custom rules
$ otel set -rule=a.json,b.json               # use default, a and b rules

Once all set up, add otel prefix to go build to build your project:

$ otel go build
$ otel go build -o app cmd/app
$ otel go build -gcflags="-m" cmd/app

The detailed usage of otel tool can be found in Usage.

Note

If you find any compilation failures while go build works, it's likely a bug. Please feel free to file a bug at GitHub Issues to help us enhance this project.

Examples

You can also explore these examples to get hands-on experience. They are designed to construct a full picture of how to use the tool in different scenarios.

Also there are several documents that you may find useful for either understanding the project or contributing to it.
