SNMP Trap Sensor (Enterprise Edition only)

The  SNMP Trap Sensor can receive traps, sent from another network device over port 162. Traps are messages sent from many network devices to announce certain warnings or problems. For example, many printers send a trap when there is too little paper.

The network device must normally be configured so that the traps are sent to the computer where ServerSentinel is running.

Please note: To receive the traps you must add an exception to the firewall. During the installation an exception for the Windows firewall is created. Should you use another firewall, check to see if it adopted the settings of the Windows firewall. Otherwise, please add an exception for ServerSentinel.

You can configure the sensor so that it receives all of the traps that are sent to the computer or you can only receive traps from certain devices. For this purpose, you can define a filter that comes from an IP address or subnet mask. The standard setting of "0.0.0.0" is set so that traps are received from all of the devices. You can also directly add the IP address of the device from which you wish to receive traps, then you will receive traps solely from this device. Furthermore, you can also add a subnet mask. By doing so you can receive traps from all of the devices that are found within the subnet.
