=head1 NAME
snmp__netapp_cifscalls - Munin plugin to retrieve cifs calls types stats from NetApp storage appliances.
=head1 APPLICABLE SYSTEMS
cifs calls stats 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 calls by type.
This can help you determine what calls types are killing your appliance under heavy
loads.
=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.
