=head1 NAME
snmp__syno_temperature - Munin plugin to retrieve current temperature from a
Synology NAS.
=head1 APPLICABLE SYSTEMS
Any Synology NAS device which provides the synoSystem 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
This plugin queries the current temperature of the NAS.
=head1 MIB INFORMATION
This plugin requires support for the synoSystem MIB by Synology.
It reports the contents of the temperature OID.
=head1 MAGIC MARKERS
#%# family=snmpauto
#%# capabilities=snmpconf

=head1 BUGS
