As with most cookbooks I write, this one is hopefully flexible enough to be wrapped by allowing you to override as much as possible

grafana::default

{
  'graphite' => {
    'type' => "'graphite'",
    'url'  => 'window.location.protocol+"//"+window.location.hostname+":"+window.location.port+"/_graphite"',
    'default' => true
  },
  'elasticsearch' => {
    'type' => "'elasticsearch'",
    'url'  => 'window.location.protocol+"//"+window.location.hostname+":"+window.location.port',
    'index' => "'#{node['grafana']['grafana_index']}'",
    'grafanaDB' => true
  }
}

kibana::nginx

Attribute	Default	Description
node['grafana']['nginx']['template']	'grafana-nginx.conf.erb'	The template file to use for the nginx site configuration
node['grafana']['nginx']['template_cookbook']	'grafana'	The cookbook containing said template

Removed:

• node['grafana']['nginx']['enable_default_site'] - use node['nginx']['enable_default_site']

Usage

grafana::default

The default recipe will:

• install Grafana from master into /opt/grafana/master and create a symlink called current in the same directory to master
• install nginx and serve the grafana application

If you want to use the file distribution of Grafana update node['grafana']['install_type'] attribute to file. Set node['grafana']['checksum'] to appropriate sha256 value of latest archive file.

If you don't want this cookbook to handle the webserver config simply set node['grafana']['webserver'] to '' in a role/environment/node somewhere. Please note that in this case you have to set node['grafana']['user'].

Nginx recipe, by default, will configure the appropriate proxy to your ElasticSearch server such that you don't have to expose it to the world.

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
