Datadog Cookbook

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

Requirements

• chef >= 10.14

Platforms

• Amazon Linux
• CentOS
• Debian
• RedHat
• Scientific Linux
• Ubuntu
• Windows (requires chef >= 12.0)

Cookbooks

The following Opscode cookbooks are dependencies:

• apt
• chef_handler
• windows
• yum

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

Note for Windows: With Chef >= 12.6 and the windows cookbook >= 1.39.0, Agent upgrades are known to fail. For Chef>=12.6 users on Windows, we recommend pinning the windows cookbook to a lower version (~> 1.38.0 for instance). If that's not an option, a known workaround is to use the remove-dd-agent recipe (since the 2.5.0 version of the present cookbook) to uninstall the Agent prior to any Agent upgrade.

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-(python|ruby)

Installs the language-specific libraries to interact with dogstatsd.

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.

Usage

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

cookbook 'datadog', '~> 2.1.0'

2. Add your API Key as a node attribute via an environment or role or by declaring it in another cookbook at a higher precedence level.
3. Create an 'application key' for chef_handler here, and add it as a node attribute, as in Step #2.
4. 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:

name 'example'
description 'Example role using DataDog'

default_attributes(
  'datadog' => {
    'api_key' => 'api_key',
    'application_key' => 'app_key'
  }
)

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

5. 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.
