snmp__netapp_net

Name

snmp__netapp_cifs - Munin plugin to retrieve general cifs information from NetApp storage appliances.

Applicable Systems

cifs should be reported by any NetApp storage appliance with SNMP agent daemon activated. See na_snmp(8) for details.

Configuration

Unfortunately, SNMPv3 is not fully supported on all NetApp equipment. 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.

Interpretation

The plugin reports various cifs connections, users and open files.

Mib Information

This plugin requires support for the NETWORK-APPLIANCE-MIB issued by Network Appliance. It reports the content of the cifs OID.

Magic Markers

#%# family=snmpauto
#%# capabilities=snmpconf

Bugs

This plugin wasn’t tested on many hardware and only on Ontap 7.3.x.
