+=head1 NAME
+
+snmp__netapp_cifs -  Munin plugin to retrieve general cifs information from NetApp storage appliances.
+
+=head1 APPLICABLE SYSTEMS
+
+cifs should be reported by any NetApp storage appliance
+with SNMP agent daemon activated. See na_snmp(8) for details.
+
+=head1 CONFIGURATION
+
+Unfortunately, SNMPv3 is not fully supported on all NetApp equipments.
+For this reason, this plugin will use SNMPv2 by default, which is
+insecure because it doesn't encrypt the community string.
+
+The following parameters will help you get this plugin working :
+
+[snmp_*]
+env.community MyCommunity
+
+If your community name is 'public', you should really worry about
+security and immediately reconfigure your appliance.
+
+Please see 'perldoc Munin::Plugin::SNMP' for further configuration.
+
+=head1 INTERPRETATION
+
+The plugin reports various cifs connections, users and open files.
+
+=head1 MIB INFORMATION
+
+This plugin requires support for the NETWORK-APPLIANCE-MIB issued by
+Network Appliance. It reports the content of the cifs OID.
+
+=head1 MAGIC MARKERS
+
+  #%# family=snmpauto
+  #%# capabilities=snmpconf
+
+=head1 BUGS
+
+This plugin wasn't tested on many hardware and only on Ontap 7.3.x.
