Description
This is a Puppet module for installing, managing and configuring the Heartbeat lightweight shipper for uptime monitoring by elastic. It has been tested on Puppet 5.x and on the following OSes: Debian 9.1, CentOS 7.3, Ubuntu 16.04
Setup
What heartbeat affects
heartbeat
configures the package repository to fetch the software, it installs it, it configures both the application (/etc/heartbeat/heartbeat.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
heartbeat
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 heartbeat
The module can be installed manually, typing puppet module install norisnetwork-heartbeat
, or by means of an environment manager (r10k, librarian-puppet, ...).
heartbeat
requires at least the outputs
and monitors
sections in order to start. Please refer to the software documentation to find out the available monitors and the supported outputs. On the other hand, the sections logging and queue already contains meaningful default values.
A basic setup checking a host by ping/icmp every 5 minutes and writing the results directly in Elasticsearch:
class{'heartbeat':
monitors => [
{
'type' => 'icmp',
'schedule' => '*/5 * * * * * *',
'hosts' => ['myhost', 'myotherhost'],
},
],
outputs => {
'elasticsearch' => {
'hosts' => ['http://localhost:9200'],
'index' => 'heartbeat-%{+YYYY.MM.dd}',
},
},
The same example using Hiera:
classes:
include:
- 'heartbeat'
heartbeat::monitors:
- type: 'icmp'
schedule: '*/5 * * * * * *'
hosts:
- 'myhost'
- 'myotherhost'
heartbeat::outputs:
elasticsearch:
hosts:
- 'http://localhost:9200'
index: "heartbeat-%%{}{+YYYY.MM.dd}"
Usage
The configuration is written to the configuration file /etc/heartbeat/heartbeat.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{'heartbeat':
monitors => [
{
'type' => 'icmp',
'schedule' => '*/5 * * * * * *',
'hosts' => ['myhost', 'myotherhost'],
},
],
outputs => {
'redis' => {
'hosts' => ['localhost:6379', 'other_redis:6379'],
'key' => 'heartbeat',
},
},
or, using Hiera
classes:
include:
- 'heartbeat'
heartbeat::monitors:
- type: 'icmp'
schedule: '*/5 * * * * * *'
hosts:
- 'myhost'
- 'myotherhost'
heartbeat::outputs:
elasticsearch:
hosts:
- 'localhost:6379'
- 'itger:redis:6379'
index: 'heartbeat'
Reference
Public Classes
Class: heartbeat
Installation and configuration.
Parameters:
beat_name
: [String] the name of the shipper (default: the hostname).fields_under_root
: [Boolean] whether to add the custom fields to the root of the document (default is false).queue
: [Hash] heartbeat's internal queue, before the events publication (default is 4096 events in memory with immediate flush).logging
: [Hash] the heartbeat's logfile configuration (default: writes to/var/log/heartbeat/heartbeat
, maximum 7 files, rotated when bigger than 10 MB).outputs
: [Hash] the options of the mandatory outputs section of the configuration file (default: undef).major_version
: [Enum] the major version of the package to install (default: '6', the only accepted value. Implemented for future reference).ensure
: [Enum 'present', 'absent']: whether Puppet should manageheartbeat
or not (default: 'present').service_provider
: [Enum 'systemd', 'init'] which boot framework to use to install and manage the service (default: 'systemd').service_ensure
: [Enum 'enabled', 'running', 'disabled', 'unmanaged'] the status of the heartbeat service (default 'enabled'). In more details:- enabled: service is running and started at every boot;
- running: service is running but not started at boot time;
- disabled: service is not running and not started at boot time;
- unamanged: Puppet does not manage the service.

Private Classes
Class: heartbeat::repo
Configuration of the package repository to fetch heartbeat.
Class: heartbeat::install
Installation of the heartbeat package.
Class: heartbeat::config
Configuration of the heartbeat daemon.
Class: heartbeat::service
Management of the heartbeat service.
Limitations
This module does not load the index template in Elasticsearch nor the heartbeat 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 heartbeat dashboards in Kibana.
The option manage_repo
does not work properly on SLES. This means that, even if set to false, the repo file
/etc/zypp/repos.d/beats.repo
will be created and the corresponding repo will be enabled.
Development
Please feel free to report bugs and to open pull requests for new features or to fix a problem.
