+
+#### default['collectd-custom']['plugins']
+
+You can specify all the plugins you want and their configuration values directly from attributes if you please. A set number of defaults are installed automatically, but you can remove them as you see fit.
+
+```ruby
+ 'logfile' => { 'config' => {
+ 'LogLevel' => 'info',
+ 'File' => '/var/log/collectd-custom.log',
+ 'Timestamp' => true
+ } },
+ 'cpu' => {},
+ 'load' => {},
+ 'swap' => {},
+ 'memory' => {},
+ 'disk' => { 'config' => {
+ 'Disk' => '/^xv/',
+ 'IgnoreSelected' => false
+ } },
+ 'interface' => { 'config' => {
+ 'Interface' => 'eth0',
+ 'IgnoreSelected' => false
+ } }
+```
+
+Alternatively, you can install them via the [`collectd_plugin`](#definitions) or [`collectd_python_plugin`](#definitions) definitions.
+
+Recipes
+-------
+
+#### collectd-custom::default
+
+This recipe will install all dependencies (except for credis), compile collectd from source, create configuration files, install plugins, and setup collectd as a service.
+
+To use, just add it to your node's `run_list`, or in the case of Engine Yard, reference it from another cookbook:
+
+```ruby
+include_recipe "collectd-custom"
+```
+
+#### collectd-custom::plugins
+
+This recipe is automatically included via `collectd-custom::default` so you don't need to specify it yourself.
+
+This recipe will install any plugins configured via the node attributes and delete any plugins that were automatically generated and no longer in use.
+
+#### collectd-custom::librato
+
+This recipe is optional.
+
+This recipe will install collectd-librato and configure your custom collectd process to report to it. You must provide `node['collectd-custom']['librato']['email']` and `node['collectd-custom']['librato']['api_token']` for this to work properly.
+
+To use, just add it to your node's `run_list`, or in the case of Engine Yard, reference it from another cookbook after the `default` recipe:
+
+```ruby
+include_recipe "collectd-custom"
+include_recipe "collectd-custom::librato"
+```
+
+#### collectd-custom::graphite
+
+This recipe is optional.
+
+This recipe will enable the collectd graphite write plugin for reporting its metrics. You must provide `node['collectd-custom']['graphite']['host']` for this to work properly. Even if you don't host Graphite yourself, it may be useful to enable this while testing on EY Local or Vagrant.
+
+To use, just add it to your node's `run_list`, or in the case of Engine Yard, reference it from another cookbook after the `default` recipe:
+
+```ruby
+include_recipe "collectd-custom"
+include_recipe "collectd-custom::graphite"
+```
+
+#### collectd-custom::monit
+
+This recipe is optional.
+
+This recipe will setup monit to track your custom collectd process. Otherwise, it will not restart if it crashes or gets killed. You can also set it up in `inittab` if you prefer, but that recipe is not provided.
+
+To use, just add it to your node's `run_list`, or in the case of Engine Yard, reference it from another cookbook after the `default` recipe:
+
+```ruby
+include_recipe "collectd-custom"
+include_recipe "collectd-custom::monit"
+```
+
+You may also need to define your monit service in another of your cookbooks if you haven't already. This is for the proper reload notifications to work. To do that, include the following in another of your recipes, maybe `monit::service`:
+
+```ruby
+service "monit" do
+ supports [:start, :restart, :reload, :stop]
+ action :nothing
+end
+```
+
+#### collectd-custom::credis
+
+This recipe is required if you intend to use the redis plugin.
+
+This recipe will download and compile [credis](https://code.google.com/p/credis/) for use when compiling collectd. Failure to include this recipe will result in no redis plugin being compiled.
+
+To use, just add it to your node's `run_list`, or in the case of Engine Yard, reference it from another cookbook. It **must** come before the `default` recipe:
+
+```ruby
+include_recipe "collectd-custom::credis"
+include_recipe "collectd-custom"
+```
+
+If you previously had collectd compiled before including the redis plugin, you will need to recompile. That recipe is provided.
+
+#### collectd-custom::recompile
+
+This recipe is optional and advisable to use only after making drastric changes.
+
+This recipe will remove collectd and recompile it from source. Useful if you added plugin depencides after collectd has already been compiled but needs recompiling to get those plugins enabled.
+
+**NOTE:** This recipe should not be necessary for version upgrades.
+
+To use, just add it to your node's `run_list`, or in the case of Engine Yard, reference it from another cookbook replacing the `default` recipe:
+
+```ruby
+include_recipe "collectd-custom::recompile"
+```
+
+#### collectd-custom::simplercpu
+
+This recipe is optional but recommended.
+
+This recipe will enable an aggregate plugin to aggregate CPU measurements per [Librato's recommendations](https://github.com/librato/collectd-librato/blob/master/README.md#simpler-cpu-metrics). Even if you aren't using Librato, consoliding your CPU measurements may be helpful.
+
+To use, just add it to your node's `run_list`, or in the case of Engine Yard, reference it from another cookbook replacing the `default` recipe:
+
+```ruby
+include_recipe "collectd-custom::simplercpu"
+```
+
+Definitions
+-----------
+
+You can install collectd plugins from your own recipes too.
+
+```ruby
+collectd_plugin "postgresql" do
+ cookbook "main" # default: collectd-custom
+ template "postgresql.plugin.conf.erb" # default: plugin.conf.erb
+ options({
+ 'Database' => {
+ 'myapp' => { 'Host' => 'localhost', 'Port' => '5432', 'User' => 'postgres', 'Password' => node[:owner_pass] }
+ }
+ })
+ only_if { node[:instance_role] == 'db_master' }
+end
+```
+
+Or for python plugins:
+
+```ruby
+collectd_python_plugin "collectd-librato" do
+ path "/usr/local/bin/some-plugin.py"
+ module "some-module"
+ options({
+ 'ApiToken' => 'some-token'
+ })
+end
+```
+
+So it may be useful for you to end up with your own `collectd-plugins` cookbook that generates your plugin configurations. For example, in my `main::default` recipe, I would include the plugins I defined:
+
+```ruby
+include_recipe "collectd-custom::librato" unless vagrant?
+include_recipe "collectd-custom::graphite" if vagrant?
+
+include_recipe "collectd-plugins::df"
+include_recipe "collectd-plugins::filecount"
+include_recipe "collectd-plugins::memcached" if util?(:memcached)
+include_recipe "collectd-plugins::nginx" if app_server?
+include_recipe "collectd-plugins::postgresql" if db_server?
+include_recipe "collectd-plugins::redis" if util?(:redis)
+include_recipe "collectd-plugins::resque" if util?(:redis)
+```
+
