Parameterized attributes for df, interface, and syslog plugin, and added a recipe for the load plugin.

README.md

@@ -21,6 +21,23 @@ A number of recipes for standard plugins are available:
 
 It is recommended to always enable the first two (rrdtool and syslog), but the others are entirely optional. For convenience, the `collectd_plugins` default recipe will include all of these.
 
+# ATTRIBUTES #
+
+Several of the plugins use host attributes to control behavior.
+
+## df plugin ##
+* `node['collectd_plugins']['df']['selected_fstypes']` - array of filesystem types to monitor or ignore.  If `'ignore_selected'` is true (default), this is a list of ignored types, and if it's false, it's a whitelist.  The default value is `["proc", "sysfs", "fusectl", "debugfs", "securityfs", "devtmpfs", "devpts", "tmpfs"]`.
+* `node['collectd_plugins']['df']['ignore_selected']` - boolean value; if true, use the `'selected_fstypes'` attribute as a blacklist; if false, treat `'selected_fstypes'` as a whitelist.  The default is true.
+* `node['collectd_plugins']['df']['report_reserved']` - boolean value; controls if we measure reserved space on the filesystem.  Defaults to false.
+* `node['collectd_plugins']['df']['report_inodes']` - boolean value; controls if we measure inode counts on the filesystem.  Defaults to false.
+
+## syslog plugin ##
+* `node['collectd_plugins']['syslog']['log_level']` - string; syslog priority used.  Allowable values are: emerg, alert, crit, err, warning, notice, info, debug.  Default is 'info'.
+
+## interface plugin ##
+* `node['collectd_plugins']['interface']['selected_interfaces']` - array of network interfaces to monitor or ignore.  If `'ignore_selected'` is true (default), this is a list of ignored types, and if it's false, it's a whitelist.  The default value is `[ "lo" ]`.
+* `node['collectd_plugins']['interface']['ignore_selected']` - boolean value; if true, use the `'selected_interfaces'` attribute as a blacklist; if false, treat `'selected_fstypes'` as a whitelist.  The default is true.
+
 ## Redis ##
 
 A plugin to monitor [Redis](http://redis.io/) is included as `collectd_plugins::redis`. This recipe requires that you be using our [redis cookbook](https://github.com/AtariTech/cookbooks/tree/master/redis)
