Puppet & Datadog

Description

A module to:

1. Install the DataDog Agent.
2. Send Puppet run reports to Datadog.

Releases

There are currently two actively maintained versions for the Puppet module. For users on Puppet >= 4.6.x, and possibly some older 4.x puppets, it is recommended to use version 2.0+ of the module.

For users running on older versions of Puppet the legacy module, series 1.x, should support most use-cases.

The majority of users should be able to use the newer module as many of the Puppet versions supported in the 1.x series of the module have been EOL'd.

Some features might be back-ported if there's enough demand, but in general only maintenance is performed on the 1.x series of the module. Future feature development is performed on the newer Puppet module.

Version 2.x

Requirements

Puppet >=4.6.x and <=5.3.x (may work with newer versions, but is untested). For detailed information 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

Note: For CentOS versions <7.0, specify the service provider as upstart:

class{ 'datadog_agent':
    service_provider => 'upstart'
  }

Upgrade from the previous module version 1.x

Most of the manifests are backward compatible. However, there are important changes to the main manifest:

• By default Datadog Agent 6.x is installed.
  • To use Agent 5.x in your nodes set the agent5_enable boolean parameter to True.
• Enhanced support for our APM Tracing Agent.
• Enhanced support for our Process Agent.
• Enhanced support for additional agent6 options.
• APM Tracing and Process Agents are now opt-in options and are disabled by default.
  • The main datadog_agent class has parameters to enable and configure the Agents easily.
• Increased granularity for apt/yum repo configuration.
• New location for Datadog Puppet reporting configuration.

Version 1.x

Requirements

Puppet >=2.7.x and <=4.2.x (may work with newer versions, but is untested). For detailed information 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 --version 1.12.1

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 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

Usage

The following instructions are for both Puppet module versions (1.x, 2.x).

Note: 2.x installs Agent v6 by default, whereas 1.x defaults to Agent v5.

Once the datadog_agent module is installed on your puppetserver/puppetmaster, follow these configuration steps:

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 => "<YOUR_DD_API_KEY>",
   }
   

   On your puppetserver, enable reporting:

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

   • To support reporting, your Puppet master needs the dogapi gem installed. To install, either run the Puppet Agent on your master with this configuration or install it manually with gem. You might need to restart your puppetserver service for the freshly installed dogapi-rb gem to be picked up.
   • On version 2.x, puppetserver_gem is defined as a module dependency, it is installed automatically when the module is installed.
   • On version 1.x:
     • If you are on Puppet Enterprise or POSS (ie. >=3.7.0), there is a soft dependency for reporting on the puppetserver_gem module. Install with puppet module install puppetlabs-puppetserver_gem - installing manually with gem does not work.
     • You may install dogapi-rb with gem as the system-level Ruby is used.
     • The gem provider is configurable by setting it to puppetserver_gem (set by default on PE/POSS (>=3.7.0)) or gem if on older versions of Puppet.
       • For users running puppet in standalone/masterless mode you will need to set the puppet_gem_provider to puppet_gem (or gem depending on versions) to ensure the dogapi-rb is available.

3. Include any other integrations you want the agent to use, for example:

   include 'datadog_agent::integrations::mongo'
   

   Some integrations do not come as a dedicated class. To install one of them, add its configuration in the manifest. Below is an example for the ntp check:

   class { 'datadog_agent':
       api_key      => "<YOUR_DD_API_KEY>",
       integrations => {
           "ntp" => {
               init_config => {},
               instances => [{
                   offset_threshold => 30,
               }],
           },
       },
   }
   

Installing and pinning specific versions of integrations

You can specify a given integration and version number to be installed by using datadog_agent::install_integration. This will use the datadog-agent integration command to ensure a specific integration is installed or uninstalled.

datadog_agent::install_integration { "mongo-1.9":
    ensure => present,
    integration_name => 'datadog-mongo',
    version => '1.9.0',
}

The field ensure can be either present (default) or absent, the later being useful to remove a previously pinned version of an integration.

Reporting

Ensure dogapi-rb is available on your system as explained earlier.

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 send a run report after each check-in back to the master.

Set the puppet_run_reports option to true in the node configuration manifest for your master:

class { "datadog-agent":
    api_key => "<YOUR_DD_API_KEY>",
    puppet_run_reports => true
    # ...
}

On Puppet >=4.x the location for your configuration file is /etc/puppetlabs/puppet/puppet.conf.

On older Puppets, the location is /etc/puppet/puppet.conf.

Add these configuration options in the pertinent location:

[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

On all of your Puppet client nodes add the following in the same location:

[agent]
# ...
report=true

If you see the following, ensure reports=datadog_reports is defined in [master], not [main].

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

Step-by-step

This is the minimal set of modifications to get started. These files assume Puppet 4.5.x or higher.

/etc/puppetlabs/puppet/puppet.conf

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

[agent]
report = true
pluginsync = true

Note: This may be file /etc/puppet/puppet/puppet.conf on older puppets

/etc/puppetlabs/code/environments/production/manifests/10_nodes.pp

node "default" {
    class { "datadog_agent":
        api_key => "<YOUR_DD_API_KEY>",
    }
}
node "puppetmaster" {
    class { "datadog_agent":
        api_key            => "<YOUR_DD_API_KEY>",
        puppet_run_reports => true
    }
}

Note: This may be file /etc/puppet/manifests/nodes.pp on older puppets

Run Puppet Agent

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

Example response:

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

1. Search for puppet on the Integrations page. The Puppet integration tile displays the install status.

2. Search for sources:puppet in the Event Stream to see your Puppet events.

Masterless Puppet

To use this specific setup, see https://gist.github.com/LeoCavaille/cd412c7a9ff5caec462f. This applies to older puppets and is untested on >=4.x Puppet versions.

Client Settings

Tagging client nodes

The Datadog Agent configuration file is recreated from the template every Puppet run. If you need to tag your nodes, add an array entry in Hiera:

datadog_agent::tags:
- 'keyname:value'
- 'anotherkey:%{factname}'

These variables can be set in the datadog_agent class to control settings in the Agent:

2.x

variable name	description
collect_ec2_tags	Set this to yes to have an instance's custom EC2 tags used as agent tags.
collect_instance_metadata	Set this to yes to have an instance's EC2 metadata used as agent tags.
datadog_site	The Datadog site to report to. Defaults to datadoghq.com, set to datadoghq.eu to report to the EU site. Supported since v2.4.0 of the module, and only with Agent v6+
dd_url	The Datadog intake server URL. You are unlikely to need to change this. Overrides datadog_site
host	Overrides the node's host name.
local_tags	An array of <KEY:VALUE> strings that are set as tags for the node.
non_local_traffic	Set this to allow other nodes to relay their traffic through this one.
agent5_enable	A boolean to install Agent v5 and override the Agent v6 default.
apm_enabled	A boolean to enable the APM Agent (defaults to false).
apm_analyzed_spans	A hash to add APM events for the Trace Search & Analytics tool. (defaults to undef). For example: { 'app\|rails.request' => 1, 'service-name\|operation-name' => 0.8 }
process_enabled	A boolean to enable the process agent (defaults to false).
scrub_args	A boolean to enable the process cmdline scrubbing (defaults to true).
custom_sensitive_words	An array to add more words beyond the default ones used by the scrubbing feature (defaults to []).
logs_enabled	A boolean to enable the logs agent (defaults to false).
container_collect_all	A boolean to enable logs collection for all containers.
agent6_extra_options	A hash to provide additional configuration options to Agent v6.
hostname_extraction_regex	A regex used to extract the hostname captured group to report the run in Datadog instead of reporting the Puppet nodename, for example:'^(?<hostname>.*\.datadoghq\.com)(\.i-\w{8}\..*)?$'

Notes:

• agent6_extra_options is used to provide a fine grain control of additional Agent v6 config options. A deep merge is performed that may override options provided in the datadog_agent class parameters.
• hostname_extraction_regex is useful when the Puppet module and the Datadog Agent are reporting different host names for the same host in the infrastructure list.

1.x

variable name	description
collect_ec2_tags	Set this to yes to have an instance's custom EC2 tags used as agent tags.
collect_instance_metadata	Set this to yes to have an instance's EC2 metadata used as agent tags.
dd_url	The Datadog intake server URL. You are unlikely to need to change this.
host	Overrides the node's host name.
local_tags	An array of <KEY:VALUE> strings that are set as tags for the node.
non_local_traffic	Set this to allow other nodes to relay their traffic through this one.
agent6_enable	A boolean to install Agent v6 and override the Agent v5 default.

Proxy Settings

To connect to the Internet through a proxy, set proxy_host, proxy_port, proxy_user and proxy_password.

2.0.0 / 2018-02-27

Overview

This release is a mejor release, there are a some breaking changes. We have tried to keep the interface as similar as possible to what the community was already used to, but have had to make some changes and cleaned up some of the interfaces to some classes. Most notably the main datadog_agent class, and the datadog_agent::ubuntu and datadog_agent::redhat.

Most checks manifest should remain backward compatible.

Please note this new release will install datadog agent version 6.x by default.

Finally, deprecated modules and support for EOL'd puppets has been dropped so if you're running a puppet server <= 4.5.x or PE <= 2016.4.x although the module might work for some versions, it has not been tested in those environments.

Please read the docs for more details.
