Grafana Cookbook

Build Status Cookbook Version

Overview

A stand-alone cookbook for Grafana. The 2.x versions of this cookbook work with the 2.x versions of Grafana. There is no backward compatibility for pre-2.0 versions of Grafana in the 2.x versions of this cookbook.

If you would like to configure pre-2.0 versions of Grafana, please use the 1.x branch and 1.x versions of this cookbook in the supermarket. There is a 1.x tag for PRs or Issues related to the 1.x branch.

Requirements

Chef Client

  • Chef Client 13+

Platforms

  • Ubuntu >= 14.04
  • Debian >= 8
  • CentOS/Redhat >= 6

Cookbooks

Recipes

node['grafana']['nginx']['httpasswd_file'] /etc/nginx/htpasswd.users The basic auth user/password file to use

NOTE

This cookbook does nothing to generate the basic auth user/password file, you will have to make sure this file is created and is valid.

Usage

grafana::default

The default recipe will:

  • install Grafana via downloaded system package
  • install nginx to proxy the grafana application

If you want to install the Grafana package repository, update node['grafana']['install_type'] attribute to package. Additionally, the node['grafana']['version'] can be set to 'latest' so that the very latest Grafana build is used instead of the default release.

Nginx is used to proxy Grafana to run on port 80. If you don't want this cookbook to handle the webserver config simply set node['grafana']['webserver'] to '' in a role/environment/node somewhere.

NOTE There is NO security enabled by default on any of the content being served. If you would like to modify the nginx parameters, you should:

  • create your own cookbook i.e. my-grafana
  • copy the template for the webserver you wish to use to your cookbook
  • modify the template as you see fit (add auth, setup ssl)
  • use the appropriate webserver template attributes to point to your cookbook and template

grafana::plugins

This recipe will install the plugins given with the node['grafana']['plugins'] attribute

It will use the grafana_plugin LWRP described in the section below.

Resources

It's important to note that Grafana must be running for these resources to be used because they utilize Grafana's HTTP API. In your recipe, you'll simply need to make sure that you include the default recipe that starts Grafana before using these.

grafana_datasource

You can control Grafana dataSources via the grafana_datasource LWRP. Due to the varying nature of the potential data sources, the information used to create the datasource is consumed by the resource as a Hash (the source attribute). The examples should illustrate the flexibility. The full breadth of options are (or will be) documented on the Grafana website, however you can discover undocumented parameters by inspecting the HTTP requests your browser makes to the Grafana server.

Properties

Property Type Default Value Description
host String 'localhost' The host grafana is running on
port Integer 3000 The port grafana is running on
admin_user String 'admin' A grafana user with admin privileges
admin_password String 'admin' The grafana user's password
datasource Hash {} A Hash of the values to create the datasource. Examples below.
action String create Valid actions are create, update, and delete.

Examples

You can create a data source for Graphite as follows:

grafana_datasource 'graphite-test' do
  datasource(
    type: 'graphite',
    url: 'http://10.0.0.15:8080',
    access: 'direct'
  )
end

You can create a data source for InfluxDB 0.8.x and make it the default dashboard as follows:

grafana_datasource 'influxdb-test' do
  datasource(
    type: 'influxdb_08',
    url: 'http://10.0.0.10:8086',
    access: 'proxy',
    database: 'metrics',
    user: 'dashboard',
    password: 'dashpass',
    isdefault: true
  )
  action :create
end

Based on you version of Grafana, value for the type key to use InfluxDB 0.9.x, need to be 'influxdb' instead of 'influxdb_08'.

You can update an existing datasource as follows:

grafana_datasource 'influxdb-test' do
  datasource(
    type: 'influxdb_09',
    url: 'http://10.0.0.10:8086',
    access: 'proxy',
    database: 'metrics',
    user: 'dashboard',
    password: 'dashpass',
    isdefault: true
  )
  action :create
end

And even rename it:

grafana_datasource 'influxdb-test' do
  datasource(
    name: 'influxdb test',
    type: 'influxdb_08',
    url: 'http://10.0.0.10:8086',
    access: 'proxy',
    database: 'metrics',
    user: 'dashboard',
    password: 'dashpass',
    isdefault: true
  )
  action :create
end

Finally, you can also delete a datasource:

grafana_datasource 'influxdb-test' do
  action :delete
end

grafana_dashboard

Dashboards in Grafana are always going to be incredibly specific to the application, but you may want to be able to create a new dashboard along with a newly provisioned stack. This resource assumes you have a static json file that displays the information that will be flowing from the newly created stack.

This resource currently makes an assumption that the name used in invocation matches the name of the dashboard. This will obviously have limitations, and could change in the future. More documentation on creating Grafana dashboards via the HTTP API can be found here.

Properties

Property Type Default Value Description
host String 'localhost' The host grafana is running on
port Integer 3000 The port grafana is running on
admin_user String 'admin' A grafana user with admin privileges
admin_password String 'admin' The grafana user's password
dashboard String A Hash of the values to create the dashboard. Examples below.
action String create Valid actions are create, update, and delete. Create can update the dashbord, be careful (see below for details) !

Examples

Assuming you have a files/default/simple-dashboard.json:

grafana_dashboard 'simple-dashboard'

If you'd like to use a my-dashboard.json with the title "title": "Test Dash":

grafana_dashboard 'test-dash' do
  dashboard(
    source: 'my-dashboard',
    overwrite: false
  )
end

If the dashboard you would like to import is already on disk with the title "title": "On Disk Dash":

grafana_dashboard 'on-disk-dash' do
  dashboard(
    path: '/opt/grafana/dashboards/local-dash.json'
  )
end

You can update a dashboard. For that, you have 2 options:

Use create action with overwrite dashboard property, like:

grafana_dashboard 'on-disk-dash' do
  dashboard(
    path: '/opt/grafana/dashboards/local-dash.json',
    overwrite: true
  )
  action :create
end

Or use update action, which will force overwrite dashboard property to true:

grafana_dashboard 'on-disk-dash' do
  dashboard(
    path: '/opt/grafana/dashboards/local-dash.json'
  )
  action :update
end

Finally, you can delete a dashboard:

grafana_dashboard 'test-dash' do
  action :delete
end

grafana_organization

This resource will allow you to create organizations within Grafana.

More information about creating Grafana organizations via the HTTP API can be found here.

Properties

Property Type Default Value Description
host String 'localhost' The host grafana is running on
port Integer 3000 The port grafana is running on
admin_user String 'admin' A grafana user with admin privileges
admin_password String 'admin' The grafana user's password
`organization Hash {} A Hash of the values to create the organization. Examples below.
action String create_if_missing Valid actions are create, update and delete.

Examples

Assuming you would like to create a new organization called Second Org.:

grafana_organization 'Second Org.'

You can also update an existing organization (usefull to change the name of the default organization):

grafana_organization 'Main Org.' do
  organization(
    name: 'Main Org 2.'
  )
  action :update
end

You will finally be able to delete an organization (WARNING: this change is NOT supported in Grafana 2.1.3):

grafana_organization 'Second Org.' do
  action :delete
end

grafana_user

This resource will allow you to create global users within Grafana. This resource is minimally viable and only supports the addition of global non-admin users. Contribution to the functionality would be appreciated.

More information about creating Grafana users via the HTTP API can be found here.

Properties

Property Type Default Value Description
host String 'localhost' The host grafana is running on
port Integer 3000 The port grafana is running on
admin_user String 'admin' A grafana user with admin privileges
admin_password String 'admin' The grafana user's password
user Hash {} A Hash of the values to create the user. Examples below.
action String create Valid actions are create, update, delete.

Examples

Assuming you would like to create a new user...

grafana_user 'j.smith' do
  user(
    name: 'John Smith',
    email: 'test@example.com',
    password: 'test123',
    isAdmin: true
  )
  action :create
end

User's login property is not mandatory. Default goes to resource name.

To update user's details, password and permissions

grafana_user 'j.smith' do
  user(
    name: 'John Smith',
    email: 'test@example.com',
    password: 'test1234',
    isAdmin: false
  )
  action :update
end

To update user's login, use current login as resource name and new login as user property, like:

grafana_user 'j.smith' do
  user(
    name: 'John Smith',
    login: 'john.smith',
    email: 'test@example.com',
    password: 'test1234',
    isAdmin: false
  )
  action :update
end

And finally to delete a user

grafana_user 'john.smith' do
  action :delete
end

grafana_plugin

This ressource will help you to manage grafana plugins.

Properties

Property Type Default Value Description
name String '' Name of the plugin.
action String install Valid actions are install, update, remove.
grafana_cli_bin String '/usr/sbin/grafana-cli' The path to the grafana-cli binary

Examples

grafana_plugin grafana-clock-panel do
  action :install
  grafana_cli_bin '/usr/sbin/grafana-cli'
end
