=head1 NAME
snmp__processes - Munin plugin to monitor the number of processes
on an SNMP device.
=head1 APPLICABLE SYSTEMS
Any SNMP-capable device that reports the
HOST-RESOURCES-MIB::hrSystemProcesses.0 OID.
=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 total number of processes currently operating on the system.
=head1 MIB INFORMATION
This plugin requires support for the HOST-RESOURCES-MIB (RFC 2790). It
reports the contents of the hrSystemProcesses OID.
=head1 MAGIC MARKERS
#%# family=snmpauto
#%# capabilities=snmpconf
=head1 VERSION
$Id$
=head1 BUGS
None known.
Could be extended to report the value of hrSystemMaxProcesses if it
exists.
