=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.
