Understanding Passive Monitor Listeners
A Passive Monitor Listener is the component in passive monitors that listens for events to
occur. When an event occurs, the listener notifies WhatsUp Gold and associated actions are
fired.
WhatsUp Gold in installed with three Passive Monitor Listeners:
SNMP Trap Listener. This listens for SNMP traps, or unsolicited SNMP messages, that
are sent from a device to indicate a change in status.
Syslog Trap Listener. This listens for Syslog messages forwarded from devices
regarding a specific record and/or text within a record.
Windows Event Log Listener. This listens for any WinEvent; for example a service
start or stop, or logon failures.
Important: Before you can configure passive monitors, you must configure the coinciding
Passive Monitor Listener(s) on the WhatsUp Gold console via Program Options. For more
information, see Enabling the SNMP Trap listener (on page 873), Enabling the Syslog listener (on
page 875), and Enabling the Windows Event Log listener (on page 874).
Configuring the SNMP Trap Listener
To configure the SNMP Trap Listener:
1 From the WhatsUp Gold console main menu, select Configure > Program Options. The
Program Options dialog appears.
Note: If the Windows SNMP Trap Service (Control Panel > Services) is running on the
WhatsUp Gold console PC, you should stop the service. This is a precaution to prevent any
conflict with the WhatsUp Passive Monitor Listener.
