MonitorMagic SNMP traps as an alarm action
When a rule of a monitor in MonitorMagic is triggered, MonitorMagic will execute the alarm
actions that are configured in the rule. In addition to for example the possibility to send a
notification in the form of email message, MonitorMagic is able to send a notification in the form of
an SNMP trap message. MonitorMagic will contact the Microsoft SNMP Service, and instruct it to
create a SNMP trap containing as information a message string provided by MonitorMagic. An
SNMP manager application will be able to receive this message, and act on its contents. See
SNMP Trap message detailed contents for details.

MonitorMagic and SNMP traps
MonitorMagic uses the SNMP service from Microsoft for SNMP traps. The SNMP service is part
of Windows 2000/NT but not installed by default. See Installing the SNMP service for more
information. The following table shows the services and network resources that are used for
SNMP traps:

Description
Computer A Required - When the MonitorMagic service wants to
send a trap, it creates the contents of the trap and
starts communicating with the SNMP service.
Computer A Required - The SNMP service running on the same
computer as the MonitorMagic service receives
information from the MonitorMagic service and send the
trap to one or more destinations in the network.
Computer B Optional - The SNMP Trap service captures all SNMP
traps that are send to the computer it runs on. No other
service or application running on the same computer
will be able to receive SNMP traps directly. Instead,
other services and applications can communicate with
the SNMP trap service to receive traps.
Computer B Optional - The SNMP manager is the end point of the
SNMP trap and presents the trap information to the end
user or processes the trap for future use. The SNMP
Manager can operatie ins two ways:
1. Interface with the SNMP Trap service. In this case,
the SNMP Trap service receives the traps. The SNMP
Trap service must be installed and running.
2. Receive the trap directly. In this case, the SNMP
Trap service must not be running on the computer.
(if the SNMP Trap service would run, the trap will be
intercepted by the trap service and never reach the
