Note: If not set explicitly in a sensor's settings, it will connect to the IP Address or DNS Name defined in the settings of the parent device the sensor is created on.ĭefine if you want to filter traps. On the sensor's details page, click on the Settings tab to change settings. You can change all settings in the sensor's Settings tab later. Therefore, you will not see all setting fields in this dialog. It only shows the setting fields that are imperative for creating the sensor. The Add Sensor dialog appears when adding a new sensor on a device manually. See the More section below for more information.įor a general introduction to the SNMP trap receiver's configuration, please see section Monitoring Syslogs and SNMP Traps.įor a general introduction to the technology behind SNMP, please see Monitoring via SNMP section. You can use trap specific placeholders in notification templates in order to see the messages when you receive a notification. For example, instead of the Object Identifier (OID) 1.3.6.1.6.1.1.2 you would see SNMPv2-SMI-v1::enterprises.32446.1.1.2 = 0 (example from the PRTG MIB). PRTG will then be able to translate the OIDs for the traps into readable messages. Note: You can copy the Management Information Base (MIB) file for your traps into the \MIB subfolder of your PRTG installation. Alternatively, you can add the sensor to a specific device to gain all messages from this device directly this will make this sensor type faster than just using source filters. You can add the sensor to the probe device on the one hand then the sensor will receive all messages of the system running the probe.
Depending on the filters, received messages will be counted in the respective channels. With the available filter options, you can define individually which types of messages will be considered for monitoring, and which messages will be recognized as warning or error messages.
It shows the overall number of received traps per second, warning and error traps per second, as well as the number of dropped packets per second. The SNMP Trap Receiver sensor receives and analyzes Simple Network Management Protocol (SNMP) traps.
