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. =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::SNMP; my %oids = ( ndmpSessionOpened => 'SessionsOpened', ndmpBackupActive => 'BackupActive', ndmpRestoreActive => 'RestoreActive', ); if (defined $ARGV[0] and $ARGV[0] eq 'snmpconf') { print "require 1.3.6.1.4.1.789.1.10.1.0 [0-9]\n"; exit 0; } my $session = Munin::Plugin::SNMP->session(); if (defined $ARGV[0] and $ARGV[0] eq "config") { my ($host, undef, undef, undef) = Munin::Plugin::SNMP->config_session(); print "host_name $host\n" unless $host eq 'localhost'; print "graph_title $host NDMP \n"; print "graph_args --base 1000 --lower-limit 0 --rigid\n"; print "graph_vlabel NDMP status\n"; print "graph_category netapp\n"; print "graph_info This graph shows NDMP status for the $host NetApp equipment.\n"; print "graph_order "; foreach (sort keys %oids) { print "$_ "; } print "\n"; foreach my $k (sort keys %oids) { print "$k.info The number of NDMP $oids{$k}\n"; print "$k.label $oids{$k}\n"; print "$k.min 0\n"; print "$k.draw AREASTACK\n"; print "$k.type GAUGE\n"; } exit 0; } my $values = $session->get_hash ( -baseoid => '1.3.6.1.4.1.789.1.10', -cols => { 2 => 'ndmpSessionOpened', 3 => 'ndmpBackupActive', 4 => 'ndmpRestoreActive', }, ); foreach my $k (keys %oids) { my $v = 'U'; $v = $values->{0}->{$k} if (defined $values); print "$k.value $v\n"; } exit 0; __END__
