Basic Agent Usage for Amazon Linux

Overview

This page outlines the basic features of the Datadog Agent for Amazon Linux. If you haven’t installed the Agent yet, instructions can be found in the Datadog Agent Integration documentation.

Packages are available for 64-bit x86 and Arm v8 architectures. For other architectures, use the source install.

Commands

In Agent v6 and v7, the service manager provided by the operating system is responsible for the Agent lifecycle, while other commands must be run through the Agent binary directly. In Agent v5, almost everything is done through the service manager.

Configuration

The configuration files and folders for the Agent are located in:

  • /etc/datadog-agent/datadog.yaml

Configuration files for Integrations:

  • /etc/datadog-agent/conf.d/

Uninstall the Agent

sudo yum remove datadog-agent

This command removes the Agent, but does not remove:

  • The datadog.yaml configuration file
  • User-created files in the /etc/datadog-agent configuration folder
  • User-created files in the /opt/datadog-agent folder
  • The dd-agent user
  • Datadog log files

If you also want to remove these elements, run this command after removing the Agent:

sudo userdel dd-agent \
&& sudo rm -rf /opt/datadog-agent/ \
&& sudo rm -rf /etc/datadog-agent/ \
&& sudo rm -rf /var/log/datadog/

Uninstall Single Step APM Instrumentation

If you installed the Agent with Single Step APM Instrumentation, and you want to uninstall the Agent, you need to run additional commands to uninstall APM Instrumentation.

Troubleshooting

See the Agent Troubleshooting documentation.
