=head1 NAME
snmp__memory - Munin plugin to monitor memory usage of a remote host
via SNMP.
=head1 CONFIGURATION
The following configuration variables are used
host - SNMP host to contact (default taken from link name)
port - SNMP port to use (default 161)
community - SNMP community string to use (default "public")
=head1 NOTES
Based on snmp__df plugin.... If this plugin reports
different numbers from the snmp_winmem plugin it must be due
to snmp impementation quirks....
