Overview

This page outlines the basic features of the Datadog Agent for Debian. 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.

Notes:

On the 64-bit x86 architecture, Debian 7 (wheezy) and above are supported in Agent < 6.36.0/7.36.0. Debian 8 (jessie) and above are supported in Agent >= 6.36.0/7.36.0. SysVinit is supported in Agent v6.6.0+.
On the 64-bit Arm v8 architecture, Debian 9 (stretch) and above are supported.

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.

Description	Command
Start Agent as a service	`sudo service datadog-agent start`
Stop Agent running as a service	`sudo service datadog-agent stop`
Restart Agent running as a service	`sudo service datadog-agent restart`
Status of Agent service	`sudo service datadog-agent status`
Status page of running Agent	`sudo datadog-agent status`
Send flare	`sudo datadog-agent flare`
Display command usage	`sudo datadog-agent --help`
Run a check	`sudo -u dd-agent -- datadog-agent check <CHECK_NAME>`

Note: If the service wrapper is not available on your system, use:

On upstart-based systems: sudo start/stop/restart/status datadog-agent
On systemd-based systems: sudo systemctl start/stop/restart/status datadog-agent

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

To uninstall the Agent, run the following command:

sudo apt-get remove datadog-agent -y

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 apt-get remove --purge datadog-agent -y

Single Step APM 계측 제거

Single Step APM 계측을 사용하여 Agent를 설치한 경우 Agent를 제거하려면 추가 명령을 실행하여 APM 계측을 제거해야 합니다.

Troubleshooting

See the Agent Troubleshooting documentation.

Working with the embedded Agent

The Agent contains an embedded Python environment at /opt/datadog-agent/embedded/. Common binaries such as python and pip are contained within /opt/datadog-agent/embedded/bin/.

See the instructions on how to add packages to the embedded Agent for more information.
