=head1 NAME
snmp__apc_ups - Munin multigraph plugin for APC UPSes
=head1 APPLICABLE SYSTEMS
The UPS must support the PowerNet-MIB published by APC. This includes
the APC Smart-UPS series on which this plugin was tested.
=head1 CONFIGURATION
As a rule SNMP plugins need site specific configuration. The default
configuration (shown here) will only work on insecure sites/devices.
[snmp_*]
env.version 2
env.community public
In general SNMP is not very secure at all unless you use SNMP version
3 which supports authentication and privacy (encryption). But in any
case the community string for your devices should not be "public".
Please see 'perldoc Munin::Plugin::SNMP' for further configuration
information.
=head1 INTERPRETATION
Please refer to the PowerNet-MIB when in doubt.
=head1 MIB INFORMATION
This plugin requires support for the PowerNet-MIB published by APC.
=head1 PROGRAMMERS
This plugin is actually a generic SNMP multigraph plugin. If you
customize the data structures, especially %oidList and %label which is
used to drive the loops. Take care that labels and structure of these
hashes match otherwise things will disappear with not much warning.
But se munin-node.log, munin-update.log and run the plugin with
munin-run.
=head1 MAGIC MARKERS
#%# family=snmpauto
#%# capabilities=snmpconf
=head1 BUGS
Probably.
=head1 AUTHOR
Based on work by Gorlow Maxim and Andrey Yakovlev. Totaly reworked by
