Recipes

• recipe[collectd] will install collectd from source.

• recipe[collectd::packages] will install collectd (and other plugins) from packages.
• recipe[collectd::recompile] will attempt to recompile collectd.

Usage

By default this cookbook will attempt to download collectd from collectd.org. If your HTTP request includes Chef as the user agent, collectd.org returns an HTTP response with a message asking you to please stop using their downloads via Chef. It is highly recommended that you override node["collectd"]["url"] with your own download location for collectd.

      },
      "disk"      => { },
      "swap"      => { },
      "memory"    => { },
      "cpu"       => { },
      "interface" => {
        "config" => { "Interface" => "lo", "IgnoreSelected" => true }
      },
      "df"        => {
        "config" => {
          "ReportReserved" => false,
          "FSType" => [ "proc", "sysfs", "fusectl", "debugfs", "devtmpfs", "devpts", "tmpfs" ],
          "IgnoreSelected" => true
        }
      },
      "write_graphite" => {
