• Debian
  • Ubuntu
• RedHat
  • Amazon
  • CentOS

Usage

This module requires a Stackdriver account. Free trial accounts are available at their website.

Base Agent

The stackdriver class includes the client:

include stackdriver

You must specify your Stackdriver API key:

• Using Hiera (recommended)

stackdriver::apikey: 'OMGBECKYLOOKATHERBUTTITSJUSTSOBIG'

• Using Puppet Code

class { 'stackdriver':
    apikey => 'OMGBECKYLOOKATHERBUTTITSJUSTSOBIG',
}

Plugins

Usage

Two methods are supported for enabling plugins.

Using Hiera (recommended)

Configuration

Plugin settings may be configured via Hiera using the following format:

stackdriver::plugin::<plugin name>::<param>:<value>

Usage

• Using an External Node Classifier

  Load the stackdriver::plugin::<plugin name> class

• Using Hiera

  Plugins may optionally be loaded using hiera itself. NOTE: an array merge is used to collect the plugin list.

  stackdriver::plugins:
      - 'plugin name'
      - 'plugin name'
  

• Using Puppet Code

  Plugins may be enabled via puppet code while keeping the plugin settings in Hiera.

  stackdriver::plugin { 'plugin name': }
  

Using Puppet Code

Configuration

Plugin settings may be specified during class load.

Usage

• Using an External Node Classifier

  Load the stackdriver::plugin::<plugin name> class and specify the class parameters.

• Using Puppet Code

  class { 'stackdriver::plugin::<plugin name>':
      param1 => 'value',
      param2 => 'value',
  }
  

Configuration

Plugin defaults are shown using the recommended Hiera format. Values enclosed in <> do not have defaults and are required. Values enclosed in () have an undef default and are optional.

Redis

Configures the redis plugin on the local host running on port 6379. Note: this module requires hiredis-devel be available to the system.

stackdriver::plugin::redis::host:       'localhost'
stackdriver::plugin::redis::port:       '6379'
stackdriver::plugin::redis::timeout:    '2000'

Memcached

Configures the memcahed plugin on the local host running on port 11211. All settings are optional.

stackdriver::plugin::memcahed::host:       'localhost'
stackdriver::plugin::memcahed::port:       '11211'

MongoDB

Configures the MongoDB plugin on the local host running on port 27017.

stackdriver::plugin::mongo::host:       'localhost'
stackdriver::plugin::mongo::user:       'stackdriver'
stackdriver::plugin::mongo::password:   'ahzae8aiLiKoe'
stackdriver::plugin::mongo::port:       '27017'

Postgresql

Configures the Postgreqsql plugin on the local host using UNIX domain sockets. Prerequisites for this plugin are documented on Stackdriver's support site.

stackdriver::plugin::postgres::user:        'stackdriver'
stackdriver::plugin::postgres::password:    'xoiboov9Pai5e'
stackdriver::plugin::postgres::dbname:      '<REQUIRED PARAM>'

nginx

Configures the nginx plugin on the local host running on port 80 (with authentication).

stackdriver::plugin::nginx::url:        'http://127.0.0.1/nginx_status'
stackdriver::plugin::nginx::user:       'stackdriver'
stackdriver::plugin::nginx::password:   'Eef3haeziqu3j'

Configures the nginx plugin on the local host running on port 443 (SSL, no authentication, no verification).

stackdriver::plugin::nginx::url:        'https://127.0.0.1/nginx_status'
stackdriver::plugin::nginx::verifypeer: false
stackdriver::plugin::nginx::verifyhost: false

apache

Configures the apache plugin on the local host running on port 80. User and Password settings are only required if the URL requires authentication.

stackdriver::plugin::apache::user:      '(OPTIONAL USER)'
stackdriver::plugin::apache::password:  '(OPTIONAL USER PASSWORD)'
stackdriver::plugin::apache::url:       'http://127.0.0.1/mod_status?auto'

Elasticsearch

Configures the Elasticsearch plugin on the local host using port 9200. Host and Port settings are optional. Prerequisites for this plugin are documented on Stackdriver's support site.

stackdriver::plugin::elasticsearch::port:      '9200'

RabbitMQ

Configures the RabbitMQ plugin on the local host running on port 15672. The defaults for all settings are listed below. The queue names must be unique and defaults to a null string ('') if not specified.

stackdriver::plugin::rabbitmq::queues:
  - vhost:     '/'
    host:      'localhost'
    port:      '15672'
    name:      '(First Queue Name)'
    user:      'guest'
    password:  'guest'
  - vhost:     '/'
    host:      'localhost'

    password:  'guest'

Tomcat

Configures monitoring for Tomcat on the local host running JMX on port 9991.
For reference on Stackdriver's support site.

You can use the sysconfig parameter to create the /etc/sysconfig/jmxtrans override config.

stackdriver::plugin::tomcat::ensure:  'present'
stackdriver::plugin::tomcat::host:    'localhost'
stackdriver::plugin::tomcat::port:    '9991'
stackdriver::plugin::tomcat::path:    '/mnt/jmxtrans'
stackdriver::plugin::tomcat::sysconfig:
    'JAVA_HOME': '/usr/java/jdk1.7.0_45/'

Pre-requisite: Enabling JMX remote on Tomcat is outside the scope of this module, below are the changes you need to apply to your Tomcat.

# Enable JMX Monitoring on Tomcat (/etc/sysconfig/tomcat)
JAVA_OPTS="${JAVA_OPTS} -Dcom.sun.management.jmxremote"
JAVA_OPTS="${JAVA_OPTS} -Dcom.sun.management.jmxremote.port=9991"
JAVA_OPTS="${JAVA_OPTS} -Dcom.sun.management.jmxremote.authenticate=false"
JAVA_OPTS="${JAVA_OPTS} -Dcom.sun.management.jmxremote.ssl=false"
JAVA_OPTS="${JAVA_OPTS} -Djava.rmi.server.hostname=<%= @fqdn %>"
