snmp__synology_temperature
Name
snmp__syno_temperature - Munin plugin to retrieve current temperature from a Synology NAS.
Applicable Systems
Any Synology NAS device which provides the synoSystem MIB.
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.
Interpretation
This plugin queries the current temperature of the NAS.
Mib Information
This plugin requires support for the synoSystem MIB by Synology. It reports the contents of the temperature OID.
