=head1 NAME
|
|
|
|
snmp__syno_hddtemp - Munin plugin to monitor the temperature of
|
|
harddisks in an Synology NAS.
|
|
|
|
=head1 APPLICABLE SYSTEMS
|
|
|
|
Any Synology NAS device which provides the synoDisk 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 temperature of each disk installed in °C.
|
|
|
|
=head1 MIB INFORMATION
|
|
|
|
This plugin requires support for the synoDisk. It reports
|
|
the temperature of the installed disks.
