Description

This is a Puppet module for installing, managing and configuring the Packetbeat lightweight shipper for network data by elastic. It has been tested on Puppet 5.x and on the following OSes: Debian 9.1, CentOS 7.3,CentOS 8.2,Ubuntu 16.04,Ubuntu 18.04,

Setup

What packetbeat affects

packetbeat configures the package repository to fetch the software, it installs it, it configures both the application (/etc/packetbeat/packetbeat.yml) and the service (systemd by default, but it is possible to manually switch to init) and it takes care that it is running and enabled.

Setup Requirements

packetbeat needs puppetlabs/stdlib, puppetlabs/apt (for Debian and derivatives), puppetlabs-yumrepo_core (for RedHat or RedHat-like systems), puppet-zypprepo (on SuSE based systems)

Beginning with packetbeat

The module can be installed manually, typing puppet module install norisnetwork-packetbeat, or by means of an environment manager (r10k, librarian-puppet, ...).

packetbeat requires at least the outputs and section in order to start. Please refer to the software documentation to find out the supported outputs. On the other hand, the sections logging and queue already contains meaningful default values. The module also configures the listening interfaces (any is the given value and the sniffing mechanism is pcap) and it enable the flows collection. The specific transaction protocols to monitor should be explicitly configured.

A basic setup capturing the HTTP traffic from port 80 on the ethernet interface writing the results directly in Elasticsearch.

class{'packetbeat':
    interfaces => {
      'device' => 'eth0',
    },
    protocols => {
      'http' => {
        'ports' => [80],
      }
    },
    outputs => {
      'elasticsearch' => {
        'hosts' => ['http://localhost:9200'],
        'index' => 'packetbeat-%{+YYYY.MM.dd}',
      },
    },

The same example, but using Hiera

classes:
  include:
    - 'packetbeat'

packetbeat::interfaces:
  device: 'eth0'
packetbeat::protocols:
  http:
    ports:
      - 80
packetbeat::outputs:
  elasticsearch:
    hosts:
      - 'http://localhost:9200'
    index: "packetbeat-%%{}{+YYYY.MM.dd}"

Usage

The configuration is written to the configuration file /etc/packetbeat/packetbeat.yml in yaml format. The default values follow the upstream (as of the time of writing).

Send data to two Redis servers, loadbalancing between the instances.

class{'packetbeat':
    interfaces => {
      'device' => 'eth0',
    },
    protocols => {
      'http' => {
        'ports' => [80],
      }
    },
    outputs => {
      'redis' => {
        'hosts' => ['localhost:6379', 'other_redis:6379'],
        'key' => 'packetbeat',
      },
    },

If using Hiera, the above example would look like

classes:
  include:
    - 'packetbeat'

packetbeat::interfaces:
  device: 'eth0'
packetbeat::protocols:
  http:
    ports:
      - 80
packetbeat::outputs:
  redis:
    hosts:
      - 'localhost:6379'
      - 'other_redis:6379'
    key: "packetbeat"

Add the packetd module to the configuration, specifying a rule to detect 32 bit system calls. Output to Elasticsearch. Disable flow detection, detect HTTP traffic on port 8080 too and use af_packet to capture the traffic. Output to Elasticsearch.

class{'packetbeat':
    interfaces => {
      'device' => 'eth0',
      'type' => 'af_packet',
    },
    flows => {
      'enabled' => false,
    },
    protocols => {
      'http' => {
        'ports' => [80, 8080],
      }
    },
    outputs => {
      'elasticsearch' => {
        'hosts' => ['http://localhost:9200'],
        'index' => 'packetbeat-%{+YYYY.MM.dd}',
      },
    },

Similarly, in Hiera

classes:
  include:
    - 'packetbeat'

packetbeat::interfaces:
  device: 'eth0'
  type: 'af_packet'
packetbeat::flows:
  enabled: false
packetbeat::protocols:
  http:
    ports:
      - 80
      - 8080
packetbeat::outputs:
  elasticsearch:
    hosts:
      - 'http://localhost:9200'
    index: "packetbeat-%%{}{+YYYY.MM.dd}"

Private Classes

Class: packetbeat::repo

Configuration of the package repository to fetch packetbeat.

Class: packetbeat::install

Installation of the packetbeat package.

Class: packetbeat::config

Configuration of the packetbeat daemon.

Class: packetbeat::service

Management of the packetbeat service.

Class: packetbeat::params

It defines the default values of some parameters.

Limitations

This module does not load the index template in Elasticsearch nor the packetbeat example dashboards in Kibana. These two tasks should be carried out manually. Please follow the documentation to manually load the index template in Elasticsearch and to import the packetbeat dashboards in Kibana.

The option manage_repo does not remove the repo repo file, even if set to false. Please delete it manually.

The module allows to set up the x-pack section of the configuration file, in order to set the internal statistics of packetbeat to an Elasticsearch cluster. In order to do that the parameter package_ensure should be set to:

  • latest
  • 6.1.0 or a higher version Unfortunately when package_ensure is equal to installed or present, the x-pack section is removed, beacuse there is no way to know which version of the package is going to be handled (unless a specific fact is added).
