Overview

Install and configure Kibana4. Should work on any linux OS.

Module Description

This module assumes you have a working Elasticsearch installation and indices (usually an 'ELK' stack). Kibana4 only works with recent versions of Elasticsearch (1.4.4 and later). I recommend using the 'elasticsearch' output with protocol => 'http' in Logstash (supported since 1.4.0) as the default protocol => 'node' uses ES version 1.1.1 and will prevent Kibana4 from connecting.

Setup

What kibana4 affects

• Manage the elastic.co Kibana repositories
• Install the Kibana package
• Modifies configuration file if needed.
• Java installation is not managed by this module.

Beginning with kibana4

include kibana4

Usage

The elastic.co packages create a kibana user and group (999:999) and they provide an init file /etc/init.d/kibana. This is now the preferred installation method for kibana4.

include kibana4

Parameters

Check all parameters in the manifests/init.pp file.

Installation Parameters

version

Version of Kibana4 that gets installed. Defaults to the latest version available in the package_repo_version you select

install_method

This parameter is deprecated. Only package installation from official elastic.co repositories is supported.

package_repo_version

Apt or yum repository version. Defaults to '4.5'.

package_repo_proxy

Whether or not to use a proxy for downloading the kibana4 package. Default is 'undef, so no proxy will be used. This is only support with yum repositories.

service_ensure

Specifies the service state. Valid values are stopped (false) and running (true). Defaults to 'running'.

service_enable

Should the service be enabled on boot. Valid values are 'true', 'false', and 'manual'. Defaults to 'true'.

service_name

Name of the Kibana4 service. Defaults to 'kibana'.

plugins

Simple plugin support has been added, but updating existing plugins is not yet supported. A hash of plugins and their installation parameters is expected:

class { 'kibana4':
  ...
  plugins => {
    'elasticsearch/marvel' => {
       kibana4_plugin_dir => '/opt/kibana/installedPlugins', # optional - this is the default
       plugin_dest_dir    => 'marvel',                       # mandatory - plugin will be installed in ${kibana4_plugin_dir}/${plugin_dest_dir}
       url                => 'http://your_custom_url',       # necessary if using arbitrary URL
       ensure             => present,                        # mandatory - either 'present' or 'absent'
    },
    'elastic/sense' => {
       ensure          => present,
       plugin_dest_dir => 'sense',
    },
  }
}

Configuration Parameters

• See the Kibana4 documentation for a full list of kibana server properties.
• Note: If you do not specify a hash of configuration parameters, then the default kibana.yml provided by the archive or package will be left intact.
• Note: The config hash is different in version 4.1 than it is in version 4.3.

config

A hash of key/value server properties. Note that specifying a value for pid.file seems to break startup scripts as of version 4.5.

An extensive config could look like:

  ...
  config => {
    'server.port'                  => 5601,
    'server.host'                  => '0.0.0.0',
    'elasticsearch.url'            => 'http://localhost:9200',
    'elasticsearch.preserveHost'   => true,
    'elasticsearch.ssl.cert'       => '/path/to/your/cert',
    'elasticsearch.ssl.key'        => '/path/to/your/key',
    'elasticsearch.password'       => 'password',
    'elasticsearch.username'       => 'username',
    'elasticsearch.pingTimeout'    => 1500,
    'elasticsearch.startupTimeout' => 5000,
    'kibana.index'                 => '.kibana',
    'kibana.defaultAppId'          => 'discover',
    'logging.silent'               => false,
    'logging.quiet'                => false,
    'logging.verbose'              => false,
    'logging.events'               => "{ log: ['info', 'warning', 'error', 'fatal'], response: '*', error: '*' }",
    'elasticsearch.requestTimeout' => 500000,
    'elasticsearch.shardTimeout'   => 0,
    'elasticsearch.ssl.verify'     => true,
    'elasticsearch.ssl.ca'         => '[/path/to/a/CA,path/to/anotherCA/]',
    'server.ssl.key'               => '/path/to/your/ssl/key',
    'server.ssl.cert'              => '/path/to/your/ssl/cert',
    'pid.file'                     => '/var/run/kibana.pid',
    'logging.dest'                 => '/var/log/kibana/kibana.log',
  },

Testing

Rspec

You can install gem dependencies with

$ bundle install

and run tests with

$ bundle exec rake spec

Beaker-rspec

You can run beaker-spec tests which will start two vagrant boxes, one to do basic test of the archive installation method, and the other to test the package installation method. Each vagrant box also runs elasticsearch.

At this time these tests are fairly basic. We use a basic manifest in each case and ensure that the puppet return code is 2 (the run succeeded, and some resources were changed) on the first run, and ensure that the return code is 0 (the run succeeded with no changes or failures; the system was already in the desired state) on the second run.

Available node sets are centos-66-x64, centos-70-x64, ubuntu-1204-x64, ubuntu-1404-x64, debian-78-x64.

Run with:

$ BEAKER_set=centos-66-x64 bundle exec rspec spec/acceptance
