=head1 NAME

snmp__print_supplies - SNMP plugin to monitor pages printed on
printers adhering to RFC1759.

=head1 APPLICABLE SYSTEMS

Any SNMP capable printer adhering to RFC1759.  Using a command such
as "munin-node-configure --snmp xerox.skillingstad.no --snmpversion 2c
--snmpcommunity public | sh -x" should auto-detect all applicable
interfaces.

=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.

  #%# capabilities=snmpconf

=head1 BUGS

For printers having duplex module: pages != number of sheets
