=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.
=head1 MAGIC MARKERS
#%# family=snmpauto
#%# capabilities=snmpconf
=head1 VERSION

=head1 BUGS
None known.
=head1 AUTHOR
Copyright (C) 2015 Thomas Arthofer
This plugin was derived from snmp__netstat by Lars Strand with updates
