Datadog Cookbook

Chef recipes to deploy Datadog's components and configuration automatically.

This cookbook includes support for:

Datadog Agent version 6.x
Datadog Agent version 5.x

Log collection is available with Agent v6, please refer to the inline docs to enable it.

Note: This README may refer to features that are not released yet. Please check the README of the git tag/the gem version you're using for your version's documentation

Requirements

chef-client >= 12.7

If you need support for Chef < 12.7, please consider using a release 2.x of the cookbook. See the CHANGELOG for more info.

Platforms

Amazon Linux
CentOS
Debian
RedHat
Scientific Linux
Ubuntu
Windows
SUSE (requires chef >= 13.3)

Cookbooks

The following Opscode cookbooks are dependencies:

apt
chef_handler
yum

Version 7.1 or later of the apt cookbook is needed to install the Agent on Debian 9 or later.

Chef support

Chef 13 users

If you're using Chef 13 and chef_handler 1.x, you may have trouble using the dd-handler recipe. The known workaround is to update your dependency to chef_handler >= 2.1.

Chef 14 and 15 users:

In order to support Chef 12 and 13, the datadog cookbook has a dependency to the chef_handler cookbook which is now shipped as a resource in Chef 14. Unfortunately, it will display a deprecation message to Chef 14 and 15 users.

Recipes

default

Just a placeholder for now, when we have more shared components they will probably live there.

dd-agent

Installs the Datadog agent on the target system, sets the API key, and start the service to report on the local system metrics

Notes for Windows:

Because of changes in the Windows Agent packaging and install in version 5.12.0, when upgrading the Agent from versions <= 5.10.1 to versions >= 5.12.0, please set the windows_agent_use_exe attribute to true.

Once the upgrade is complete, you can leave the attribute to its default value (false).

For more information on these Windows packaging changes, see the related docs on the dd-agent wiki.

dd-handler

Installs the chef-handler-datadog gem and invokes the handler at the end of a Chef run to report the details back to the newsfeed.

dogstatsd-ruby

Installs the language-specific libraries to interact with dogstatsd.

For ruby, please use the datadog::dogstatsd-ruby recipe.

For Python, please add a dependency on the poise-python cookbook to your custom/wrapper cookbook, and use the following resource:

python_package 'dogstatsd-python' # assumes that python and pip are installed

For more advanced usage, please refer to the poise-python cookbook documentation

ddtrace-ruby

Installs the language-specific libraries for application Traces (APM).

For ruby, please use the datadog::ddtrace-ruby recipe.

For Python, please add a dependency on the poise-python cookbook to your custom/wrapper cookbook, and use the following resource:

python_package 'ddtrace' # assumes that python and pip are installed

For more advanced usage, please refer to the poise-python cookbook documentation

other

There are many other integration-specific recipes, that are meant to assist in deploying the correct agent configuration files and dependencies for a given integration.

Resources

datadog_monitor

The datadog_monitor resource will help you to enable Agent integrations.

The default action :add enables the integration by filling a configuration file for the integration with the values provided to the resource, setting the correct permissions on that file, and restarting the Agent.

The :remove action disables an integration.

Syntax

datadog_monitor 'name' do
  init_config                       Hash # default value: {}
  instances                         Array # default value: []
  logs                              Array # default value: []
  use_integration_template          true, false # default value: false
  action                            Symbol # defaults to :add if not specified
end

Actions

:add Default. Enable the integration.
:remove Use this action to disable the integration.

Properties

'name' is the name of the Agent integration to configure and enable
instances are the fields used to fill values under the instances section in the integration configuration file.
init_config are the fields used to fill values under the the init_config section in the integration configuration file.
logs are the fields used to fill values under the the logs section in the integration configuration file.
use_integration_template: set to true (recommended) to use a default template that simply writes the values of instances, init_configand logs in YAML under their respective YAML keys. (defaults to false for backward compatibility, will default to true in a future major version of the cookbook)

Example

This example enables the ElasticSearch integration by using the datadog_monitor resource. It provides the instance configuration (in this case: the url to connect to ElasticSearch) and sets the use_integration_template flag to use the default configuration template. Also, it notifies the service[datadog-agent] resource in order to restart the Agent.

Note that the Agent installation needs to be earlier in the run list.

include_recipe 'datadog::dd-agent'

datadog_monitor 'elastic'
  instances  [{'url' => 'http://localhost:9200'}]
  use_integration_template true
  notifies :restart, 'service[datadog-agent]' if node['datadog']['agent_start']
end

See recipes/ for many examples using the datadog_monitor resource.

datadog_integration

The datadog_integration resource will help you to install specific versions of Datadog integrations.

The default action :install installs the integration on the node using the agent integration install command.

The :remove action removes an integration from the node using the agent integration remove command.

Syntax

datadog_integration 'name' do
  version                           String # version to install for :install action.
  action                            Symbol # defaults to :install if not specified
end

Actions

:install Default. Installs an integration in the given version.
:remove Removes an integration.

Properties

'name' is the name of the Agent integration to install, e.g. datadog-apache
version is the version of the integration that you want to install. Only needed with the :install action.

Example

This example installs version 1.11.0 of the ElasticSearch integration by using the datadog_integration resource.

Note that the Agent installation needs to be earlier in the run list.

include_recipe 'datadog::dd-agent'

datadog_integration 'datadog-elastic'
  version '1.11.0'
end

In order to get the available versions of the integrations, please refer to their CHANGELOG.md file in the integrations-core repository.

Note for Chef Windows users: as the datadog-agent binary available on the node is used by this resource, the chef-client must have read access to the datadog.yaml file.

Usage

Agent v6

By default, this cookbook installs Agent v6, if you want to install Agent v5, please refer to the Agent v5 section below.

Attributes are available to have finer control over how you install Agent v6:

agent6_version: allows you to pin the agent version (recommended).
agent6_package_action: defaults to 'install', may be set to 'upgrade' to automatically upgrade to latest (not recommended, we recommend pinning to a version with agent6_version and change that version to upgrade).
agent6_aptrepo: desired APT repo for the agent. Defaults to http://apt.datadoghq.com
agent6_aptrepo_dist: desired distribution for the APT repo. Defaults to stable
agent6_yumrepo: desired YUM repo for the agent. Defaults to https://yum.datadoghq.com/stable/6/x86_64/

Please review the attributes/default.rb file (at the version of the cookbook you use) for the list and usage of the attributes used by the cookbook.

For general information on the Datadog Agent v6, please refer to the datadog-agent repo.

Windows Agent v6 installation

Starting with version >= 6.11, the Windows Agent v6 must be installed with datadog cookbook version >= 2.18.0.

This is due to the Agent v6 running with an unprivileged user on Windows since 6.11. However, prior to 2.18.0, the datadog cookbook was enforcing Administrators privileges to the Datadog Agent directories and files.

Extra configuration

Should you wish to add additional elements to the Agent v6 configuration file (typically datadog.yaml) that are not directly available as attributes of the cookbook, you may use the node['datadog']['extra_config'] attribute. This attribute is a hash and will be marshaled into the configuration file accordingly.

E.g.

default_attributes(
  'datadog' => {
    'extra_config' => {
       'secret_backend_command' => '/sbin/local-secrets'
    }
  }
)

This example will set the field secret_backend_command in the configuration file datadog.yaml.

Agent v5

Since 3.0.0, the cookbook defaults installing Agent v6. You can still setup the Agent v5 by setting node['datadog']['agent6'] to false.

  default_attributes(
    'datadog' => {
      'agent6' => false
    }
  )

Agent v5 transitions

Upgrade from Agent v5 to Agent v6

To upgrade from an already installed Agent v5 to Agent v6, you'll have to set the agent6_package_action to install and we recommend to pin to a specific version:

  default_attributes(
    'datadog' => {
      'agent6' => true,
      'agent6_version' => '1:6.10.0-1', # optional but recommended
      'agent6_package_action' => 'install',
    }
  )

Note that there are Agent v6 counterparts to several well known Agent v5 attributes (code here)

Downgrade from an installed Agent v6 to an Agent v5

You will need to indicate that you want to setup an Agent v5 instead of v6, pin the Agent v5 version that you want to install and allow downgrade:

  default_attributes(
    'datadog' => {
      'agent6' => false,
      'agent_version' => '1:5.32.0-1',
      'agent_allow_downgrade' => true
    }
  )

Instructions

Add this cookbook to your Chef Server, either by installing with knife or by adding it to your Berksfile:

cookbook 'datadog', '~> 3.0.0'

Add your API Key either:

as a node attribute via an environment or role, or
as a node attribute by declaring it in another cookbook at a higher precedence level, or
in the node run_state by setting node.run_state['datadog']['api_key'] in another cookbook preceding datadog's recipes in the run_list. This approach has the benefit of not storing the credential in clear text on the Chef Server.

Create an 'application key' for chef_handler here, and add it as a node attribute or in the run state, as in Step #2.

NB: if you're using the run state to store the api and app keys you need to set them at compile time before datadog::dd-handler in the run list.
Enable Agent integrations by including their recipes and configuration details in your role’s run-list and attributes. Note that you can also create additional integrations recipes by using the datadog_monitor resource.
Associate the recipes with the desired roles, i.e. "role:chef-client" should contain "datadog::dd-handler" and a "role:base" should start the agent with "datadog::dd-agent". Here's an example role with both recipes plus the MongoDB integration enabled.

name 'example'
description 'Example role using DataDog'

default_attributes(
  'datadog' => {
    'agent6' => true,
    'api_key' => 'api_key',
    'application_key' => 'app_key',
    'mongo' => {
      'instances' => [
        {'host' => 'localhost', 'port' => '27017'}
      ]
    }
  }
)

run_list %w(
  recipe[datadog::dd-agent]
  recipe[datadog::dd-handler]
  recipe[datadog::mongo]
)

NB: set the agent6 attribute to false in the datadog hash if you'd like to install Agent v5.

Wait until chef-client runs on the target node (or trigger chef-client manually if you're impatient)

We are not making use of data_bags in this recipe at this time, as it is unlikely that you will have more than one API key and one application key.

For more deployment details, visit the Datadog Documentation site.
