NAME

snmp__users - Munin plugin to check the number of logged in users on an SNMP device.

APPLICABLE SYSTEMS

Any SNMP-capable device that reports the HOST-RESOURCES-MIB::hrSystemNumUsers.0 OID.

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.

INTERPRETATION

The number of user sessions for which this host is storing state information. A session is a collection of processes requiring a single act of user authentication and possibly subject to collective job control.

MIB INFORMATION

This plugin requires support for the HOST-RESOURCES-MIB (RFC 2790). It reports the contents of the hrSystemNumUsers.0 OID.
