Description

The filebeat module installs and configures the filebeat log shipper maintained by elastic.

Setup

What filebeat affects

By default filebeat adds a software repository to your system, and installs filebeat along with required configurations.

Setup Requirements

The filebeat module depends on puppetlabs/stdlib, and on puppetlabs/apt on Debian based systems.

Beginning with filebeat

filebeat can be installed with puppet module install pcfens-filebeat (or with r10k, librarian-puppet, etc.)

The only required parameter, other than which files to ship, is the outputs parameter.

Usage

All of the default values in filebeat follow the upstream defaults (at the time of writing).

To ship files to elasticsearch:

class { 'filebeat':
  outputs => {
    'elasticsearch' => {
     'hosts' => [
       'http://localhost:9200',
       'http://anotherserver:9200'
     ],
     'index'       => 'packetbeat',
     'cas'         => [
        '/etc/pki/root/ca.pem',
     ],
    },
  },
}

To ship log files through logstash:

class { 'filebeat':
  outputs => {
    'logstash'     => {
     'hosts' => [
       'localhost:5044',
       'anotherserver:5044'
     ],
     'loadbalance' => true,
    },
  },
}

Shipper and logging options can be configured the same way, and are documented on the elastic website.

Adding a prospector

Prospectors are processes that ship log files to elasticsearch or logstash. They can be defined as a hash added to the class declaration (also used for automatically creating prospectors using hiera), or as their own defined resources.

At a minimum, the paths parameter must be set to an array of files or blobs that should be shipped. log_type is what logstash views as the type parameter if you'd like to apply conditional filters.

filebeat::prospector { 'syslogs':
  paths    => [
    '/var/log/auth.log',
    '/var/log/syslog',
  ],
  log_type => 'syslog-beat',
}

Multiline Logs

Filebeat prospectors (versions >= 1.1) can handle multiline log entries. The multiline parameter accepts a hash containing pattern, negate, match, max_lines, and timeout as documented in the filebeat configuration documentation.

• config_file_mode: [String] The permissions mode set on configuration files (default: 0644)
• purge_conf_dir: [Boolean] Should files in the prospector configuration directory not managed by puppet be automatically purged
• outputs: [Hash] Will be converted to YAML for the required outputs section of the configuration (see documentation, and above)
• shipper: [Hash] Will be converted to YAML to create the optional shipper section of the filebeat config (see documentation)

• tmp_dir: [String] Where filebeat should be temporarily downloaded to so it can be installed (windows only)
• prospectors: [Hash] Prospectors that will be created. Commonly used to create prospectors using hiera

Private Classes

Class: filebeat::config

Creates the configuration files required for filebeat (but not the prospectors)

Class: filebeat::install

Calls the correct installer class based on the kernel fact.

Class: filebeat::params

Sets default parameters for filebeat based on the OS and other facts.

Class: filebeat::repo

Installs the yum or apt repository for the system package manager to install filebeat.

Class: filebeat::service

Configures and manages the filebeat service.

Class: filebeat::install::linux

Install the filebeat package on Linux kernels.

Class: filebeat::install::windows

Downloads, extracts, and installs the filebeat zip file in Windows.

Public Defines

Define: filebeat::prospector

Installs a configuration file for a prospector.

Be sure to read the filebeat configuration details to fully understand what these parameters do.

Parameters for filebeat::prospector

• ensure: The ensure parameter on the prospector configuration file. (default: present)
• paths: [Array] The paths, or blobs that should be handled by the prospector. (required)
• exclude_files: [Array] Files that match any regex in the list are excluded from filebeat (default: [])
• encoding: [String] The file encoding. (default: plain)
• input_type: [String] log or stdin - where filebeat reads the log from (default:log)
• fields: [Hash] Optional fields to add information to the output (default: {})
• fields_under_root: [Boolean] Should the fields parameter fields be stored at the top level of indexed documents.
• ignore_older: [String] Files older than this field will be ignored by filebeat (default: 24h)
• log_type: [String] (Deprecated - use doc_type) The document_type setting (optional - default: log)
• doc_type: [String] The event type to used for published lines, used as type field in logstash and elasticsearch (optional - default: log)
• scan_frequency: [String] How often should the prospector check for new files (default: 10s)

• max_backoff: [String] The maximum wait time to scan a file for new lines to ship (default: 10s)
• backoff_factor: [Integer] backoff is multiplied by this parameter until max_backoff is reached to determine the actual backoff (default: 2)
• partial_line_waiting: [String] How long should the prospector wait before shipping a file with a potentially incomplete last line (default: 5s)
• force_close_files: [Boolean] Should filebeat forcibly close a file when renamed (default: false)
• include_lines: [Array] A list of regular expressions to match the lines that you want to include. Ignored if empty (default: [])

Limitations

This module doesn't load the elasticsearch index template into elasticsearch (required when shipping directly to elasticsearch).

Only filebeat versions after 1.0.0-rc1 are supported. 1.0.0-rc1 and older don't support YAML like the ruby template can easily generate.
