=head1 NAME
|
|
|
|
snmp__syno_ups - Munin plugin to retrieve various information of the
|
|
UPS attached to a Synology NAS.
|
|
|
|
=head1 APPLICABLE SYSTEMS
|
|
|
|
Any Synology NAS device which provides the synoUPS MIB.
|
|
|
|
=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
|
|
|
|
The plugin reports the following stats about the UPS attached:
|
|
- Load in %
|
|
- Charge in %
|
|
|
|
=head1 MIB INFORMATION
|
|
|
|
