Puppet & Datadog

Build Status

Description

A module to:

  1. install the DataDog agent
  2. to send reports of puppet runs to the Datadog service Datadog.

Requirements

Puppet 2.7.x or 3.x. For detailed informations on compatibility, check the module page on the Puppet forge.

Installation

Install datadog_agent as a module in your Puppet master's module path.

puppet module install datadog-datadog_agent

Upgrade from previous git manual install 0.x (unreleased)

You can keep using the datadog module but it becomes legacy with the release of datadog_agent 1.0.0. Upgrade to get new features, and use the puppet forge system which is way easier for maintenance.

  • Delete the datadog module rm -r /etc/puppet/modules/datadog
  • Install the new module from the puppet forge puppet module install datadog-datadog_agent
  • Update your manifests with the new module class, basically replace datadog by datadog_agent

For instance to deploy the elasticsearch integration

include 'datadog_agent::intergrations::elasticsearch'

Usage

Once the datadog_agent module is installed on your master, there's a tiny bit of configuration that needs to be done.

  1. Update the default class parameters with your API key

  2. Specify the module on any nodes you wish to install the DataDog Agent.

    include datadog_agent
    

    Or assign this module using the Puppet style Parameterized class: class { 'datadog_agent': api_key => "yourkey", }

    On your Puppet master, enable reporting:

      class { 'datadog_agent':
        api_key            => "yourkey",
        puppet_run_reports => true,
      }
    

    To support reporting, your Puppet master needs to have the dogapi gem installed, to do that either run the puppet agent on your master with this configuration or install it manually with gem

  3. Include any other integrations you want the agent to use, e.g.

    include 'datadog_agent::integrations::mongo'
    

Reporting

To enable reporting of changes to the Datadog timeline, enable the report processor on your Puppet master, and enable reporting for your clients. The clients will send a run report after each check-in back to the master, and the master will process the reports and send them to the Datadog API.

In your Puppet master /etc/puppet/puppet.conf, add these configuration options:

[main]
# No need to modify this section
# ...

[master]
# Enable reporting to datadog
reports=datadog_reports
# If you use other reports already, just add datadog_reports at the end
# reports=store,log,datadog_reports
# ...

[agent]
# ...
pluginsync=true
report=true

And on all of your Puppet client nodes add:

[agent]
# ...
report=true

If you get

err: Could not send report:
Error 400 on SERVER: Could not autoload datadog_reports:
Class Datadog_reports is already defined in Puppet::Reports

Make sure reports=datadog_reports is defined in [master], not [main].

Step-by-step

This is the minimal set of modifications to get started. These files assume puppet 2.7.x or higher.

/etc/puppet/puppet.conf

[master]
report = true
reports = datadog_reports
pluginsync = true

[agent]
report = true
pluginsync = true

/etc/puppet/manifests/nodes.pp

node "default" {
    class { "datadog_agent":
        api_key => "INSERT YOU API KEY HERE",
    }
}
node "puppetmaster" {
    class { "datadog_agent":
        api_key            => "INSERT YOUR API KEY HERE",
        puppet_run_reports => true
    }
}

/etc/puppet/manifests/site.pp

import "nodes.pp"

Run Puppet Agent

sudo /etc/init.d/puppetmaster restart
sudo puppet agent --onetime --no-daemonize --no-splay --verbose

You should see something like:

info: Retrieving plugin
info: Caching catalog for alq-linux.dev.datadoghq.com
info: Applying configuration version '1333470114'
notice: Finished catalog run in 0.81 seconds

Verify on Datadog

Go to the Setup page and you should see this

Puppet integration

Search for "Puppet" in the Stream and you should see something like this:

Masterless puppet

This is a specific setup, you can use https://gist.github.com/LeoCavaille/cd412c7a9ff5caec462f to set it up.
