Overview

On a Linux host or VM, use Single Step Instrumentation (SSI) for APM to install the Datadog Agent and instrument your applications in one step, with no additional configuration required.

Enable APM on your applications

To enable APM on a Linux host:

1. In the Datadog app, go to the Install the Datadog Agent on Linux page.

2. In the Customize your observability coverage section, go to Additional features > Application Observability, and turn on APM Instrumentation.

3. Copy and run the Agent installation command on your Linux host or VM.

4. Restart your applications.

Set SDK tracer versions

By default, Single Step Instrumentation installs the latest major versions of Datadog APM SDKs. Minor version updates are applied automatically when they become available.

You may want to customize SDK versions based on your application’s language version or specific environment requirements. You can control the major and minor versions used by customizing library versions during setup.

To customize tracer versions:

1. In the Datadog app, go to the Install the Datadog Agent on Linux page.

2. After you turn on APM Instrumentation, click Customize library versions.

3. Find your language(s) and use the dropdown to either:

   • Pin an exact tracer version, or
   • Select the major version you want to use.

4. Copy and run the updated installation command.

Available versions are listed in source repositories for each language:

• Java (java)
• Node.js (js)
• Python (python)
• .NET (dotnet)
• Ruby (ruby)
• PHP (php)

Remove Single Step APM instrumentation from your Agent

To stop producing traces for all services on your infrastructure:

1. Run:

   dd-host-install --uninstall
   

2. Restart the services on the host or VM.
