=head1 NAME
snmp__cisco_sbs_cpu - Munin plugin to monitor CPU Usage on Cisco Small Business Switches.
=head1 APPLICABLE SYSTEMS
Cisco Small Business Switches (SBXXXX devices)
=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
CPU Percentage gives an idea of utilization of the device. High CPU
can indicate a configuration problem or overutilization of the device.
=head1 MAGIC MARKERS
#%# family=snmpauto
#%# capabilities=snmpconf
=head1 VERSION
$Id$
=head1 BUGS
None known.
