=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.

snmp__areca_ - Munin plugin to get temperature, voltage or fan speed values
|
||||
from Areca network enabled RAID controllers via SNMP.
|
||||
|
||||
=head1 APPLICABLE SYSTEMS
|
||||
|
||||
All machines with a SNMP capable ARECA raid controller.
|
||||
|
||||
=head1 CONFIGURATION
|
||||
|
||||
Make sure your Areca controller is accessible via SNMP from the munin host:
|
||||
snmpwalk -v 1 -c snmp_community ip.add.re.ss
|
||||
|
||||
The plugin is a wildcard plugin and can thus be used to retrieve different
|
||||
values depending on the name of the file.
|
||||
|
||||
Linking it as snmp_10.8.1.230_areca_fan would retrieve the fan speed values from
|
||||
the Areca controller at 10.8.1.230.
|
||||
|
||||
Valid values are fan, temp and volt.
|
||||
|
||||
Add the following to your /etc/munin/plugin-conf.d/snmp__areca file:
|
||||
|
||||
[snmp_ip.add.re.ss_*]
|
||||
community private
|
||||
version 1
|
||||
|
||||
Then test the plugin by calling the following commands:
|
||||
|
||||
munin-run snmp_10.8.1.230_areca_temp config
|
||||
munin-run snmp_10.8.1.230_areca_temp
|
||||
|
||||
Both commands should output sensible data without failing.
|
||||
|
||||
=head1 INTERPRETATION
|
||||
|
||||
The plugin shows the temperature in Celsius or the fanspeed in rotations per minute.
