#grafana
####Table of Contents
##Overview
This module installs Grafana, a dashboard and graph editor for Graphite, InfluxDB and OpenTSDB.
##Module Description
This module assumes you will be using, and has only been tested against, Graphite. Therefore it is assumed you have a Graphite installation Grafana will be pulling data from. This module does not manage Graphite in any way.
##Setup
This module assumes that you will be serving Grafana using a web server such as Apache or Nginx. It will:
- Download and extract Grafana to an installation directory or use your package manager
- Create a symlink in the installation directory to enable future version upgrades if not using a package manager
- Configure Grafana with a default Graphite and Elasticsearch host of 'localhost'
- Allow you to override the Grafana version, download URL, and Graphite / Elasticsearch urls
Add the following to your manifest to create an Apache virtual host to serve Grafana. NOTE This requires the puppetlabs-apache module.
# Grafana is to be served by Apache
class { 'apache':
default_vhost => false,
}
# Create Apache virtual host
apache::vhost { 'grafana.example.com':
servername => 'grafana.example.com',
port => 80,
docroot => '/opt/grafana',
error_log_file => 'grafana-error.log',
access_log_file => 'grafana-access.log',
directories => [
{
path => '/opt/grafana',
options => [ 'None' ],
allow => 'from All',
allow_override => [ 'None' ],
order => 'Allow,Deny',
}
]
}###Beginning with Grafana
To install Grafana with the default parameters:
class { 'grafana': }This assumes that you have Graphite running on the same server as Grafana, and that you want to install Grafana to in /opt. To establish customized parameters:
class { 'grafana':
install_dir => '/usr/local',
datasources => {
'graphite' => {
'type' => 'graphite',
'url' => 'http://172.16.0.10',
'default' => 'true'
},
'elasticsearch' => {
'type' => 'elasticsearch',
'url' => 'http://172.16.0.10:9200',
'index' => 'grafana-dash',
'grafanaDB' => 'true',
},
}
}##Usage
###Classes and Defined Types
####Class: grafana
The Grafana module's primary class, grafana, guides the basic setup of Grafana on your system.
class { 'grafana': }Parameters within grafana:
#####datasources
The graphite, elasticsearch, influxdb, and opentsdb connection properties. See init.pp for an example.
#####default_route
The default start dashboard. Defaults to '/dashboard/file/default.json'.
#####download_url
The URL to download Grafana from when using the 'archive' install method. The default is 'http://grafanarel.s3.amazonaws.com/grafana-${version}.tar.gz'.
#####grafana_group
The group that will own the installation directory. The default is 'root' and there is no login in place to check that the value specified is a valid group on the system.
#####grafana_user
The user that will own the installation directory. The default is 'root' and there is no logic in place to check that the value specified is a valid user on the system.
#####install_dir
Controls which directory Grafana is downloaded and extracted in. The default value is '/opt'.
#####install_method
Controls which method to use for installing Grafana. Valid options are 'archive' and 'package'. The default is 'archive'.
#####max_search_results
Max number of dashboards in search results. Defaults to 100.
#####symlink
Determines if a symlink should be created in the installation directory for the extracted archive. The default is 'true'.
#####symlink_name
Sets the name to be used for the symlink. The default is '${install_dir}/grafana'.
#####version
Controls the version of Grafana that gets downloaded and extracted. The default value is the latest stable version available at the time of module release.
###Templates
This module currently makes use of one template to manage Grafana's main configuration file, config.js.
##Limitations
This module has been tested on CentOS 6.4, serving Grafana with Apache. Other configurations should work with minimal, if any, additional effort.
