+=head2 Plugin C<netapp>
+
+The netapp plugin can collect various performance and capacity informations
+from a NetApp filer using the NetApp API.
+
+To collect these data collectd will log in to the NetApp via HTTP(S) and HTTP
+basic authentication.
+
+B<Do not use a regular user for this!> Create a special collectd user with just
+the minimum of capabilities needed. The user only needs the "login-http-admin"
+capability as well as a few more depending on which data will be collected.
+Required capabilities are documented below.

+
+The following options decide what kind of data will be collected. You can
+either use them as a block and fine tune various parameters inside this block,
+use them as a single statement to just accept all default values, or omit it to
+not collect any data.
+
+The following options are valid inside all blocks:
+

+The host specific interval between data collections is multiplied by this value
+for collecting these data.

+B<Note:> These are the same values that the NetApp CLI command "sysstat"
+returns in the "NFS", "CIFS", "HTTP", "FCP" and "iSCSI" fields.
+
+Optional
+
+Type: boolean
+
+Default: true
+
+Result: A variable number of value lists of type "disk_ops_complex". Each type
+of operation will result in one value list with the name of the operation as
+type instance.
+

+
+=head3 The WAFL block
+
+This will collect various performance data about the WAFL file system. At the
+moment this just means cache performance.
+
+B<Note:> To get this data the collectd user needs the
+"api-perf-object-get-instances" capability.
+
+B<Note:> The interface to get these values is classified as "Diagnostics" by
+NetApp. This means that it is not guaranteed to be stable even between minor
+releases.

+=head3 The VolumePerf block
+
+This will collect various performance data about the individual volumes.
+
+You can select which data to collect about which volume using the following
+options. They follow the standard ignorelist semantic.
+
+B<Note:> To get this data the collectd user needs the
+I<api-perf-object-get-instances> capability.
+
+=over 4
+
+=item B<GetIO> I<Volume>
+
+=item B<GetOps> I<Volume>
+
+=item B<GetLatency> I<Volume>
+
+Select the given volume for IO, operations or latency statistics collection.
+The argument is the name of the volume without the C</vol/> prefix.
+
+Since the standard ignorelist functionality is used here, you can use a string
+starting and ending with a slash to specify regular expression matching: To
+match the volumes "vol0", "vol2" and "vol7", you can use this regular
+expression:
+
+ GetIO "/^vol[027]$/"
+
+If no regular expression is specified, an exact match is required. Both,
+regular and exact matching are case sensitive.
+
+If no volume was specified at all for either of the three options, that data
+will be collected for all available volumes.
+
+=item B<IgnoreSelectedIO> B<true>|B<false>
+
+=item B<IgnoreSelectedOps> B<true>|B<false>
+
+=item B<IgnoreSelectedLatency> B<true>|B<false>
+
+When set to B<true>, the volumes selected for IO, operations or latency
+statistics collection will be ignored and the data will be collected for all
+other volumes.
+
+When set to B<false>, data will only be collected for the specified volumes and
+all other volumes will be ignored.
+
+If no volumes have been specified with the above B<Get*> options, all volumes
+will be collected regardless of the B<IgnoreSelected*> option.
+
+Defaults to B<false>
+
+=back
+
+=head3 The VolumeUsage block
+
+This will collect capacity data about the individual volumes.
+
+B<Note:> To get this data the collectd user needs the I<api-volume-list-info>
+capability.
+
+=over 4
+
+=item B<GetCapacity> I<VolumeName>
+
+The current capacity of the volume will be collected. This will result in two
+to four value lists, depending on the configuration of the volume. All data
+sources are of type "df_complex" with the name of the volume as
+plugin_instance.
+
+There will be type_instances "used" and "free" for the number of used and
+available bytes on the volume. If the volume has some space reserved for
+snapshots, a type_instance "snap_reserved" will be available. If the volume
+has SIS enabled, a type_instance "sis_saved" will be available. This is the
+number of bytes saved by the SIS feature.
+
+B<Note:> The current NetApp API has a bug that results in this value being
+reported as a 32E<nbsp>bit number. This plugin tries to guess the correct
+number which works most of the time. If you see strange values here, bug
+NetApp support to fix this.
+
+Repeat this option to specify multiple volumes.
+
+=item B<IgnoreSelectedCapacity> B<true>|B<false>
+
+Specify whether to collect only the volumes selected by the B<GetCapacity>
+option or to ignore those volumes. B<IgnoreSelectedCapacity> defaults to
+B<false>. However, if no B<GetCapacity> option is specified at all, all
+capacities will be selected anyway.
+
+=item B<GetSnapshot> I<VolumeName>
+
+B<Defunct!> Select volumes from which to collect snapshot information.
+
+Repeat this option to specify multiple volumes.
+
+=item B<IgnoreSelectedSnapshot>
+
+Specify whether to collect only the volumes selected by the B<GetSnapshot>
+option or to ignore those volumes. B<IgnoreSelectedSnapshot> defaults to
+B<false>. However, if no B<GetSnapshot> option is specified at all, all
+capacities will be selected anyway.
