=head1 NAME
snmp__apc - SNMP plugin to monitor APC metered and managed PDUs.
=head1 APPLICABLE SYSTEMS
This has been tested with AP7830 metered PDUs, but should work with
most other PDUs that follow the PowerNet-MIB published by APC.
=head1 CONFIGURATION
Most likely you want to use SNMP version 3 to connect to the PDUs, as
they don't support version 2 (only 1 or 3). This can be achieved by
using:
[snmp_*_apc]
env.version 3
Please see 'perldoc Munin::Plugin::SNMP' for further configuration
information.
=head1 MIB INFORMATION
This plugin requires the PowerNet-MIB from APC.
=head1 MAGIC MARKERS
#%# family=snmpauto
#%# capabilities=snmpconf
=head1 BUGS
None known.
