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 sis status (initialising, running, pending) per filer and per volume. This could be helpful for sis schedule optimization. =head1 MIB INFORMATION This plugin requires support for the NETWORK-APPLIANCE-MIB issued by Network Appliance. It reports the content of the sis 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. =head1 AUTHOR 2013, Claudius Herder NetApp is a registered trademark and Network Appliance is a trademark of Network Appliance, Inc. in the U.S. and other countries. =head1 LICENSE GPLv2. =cut use strict; use warnings; use Munin::Plugin; use Munin::Plugin::SNMP; need_multigraph(); if (defined $ARGV[0] and $ARGV[0] eq "snmpconf") { print "require 1.3.6.1.4.1.789.1.23.2.1.1.
