This will give us a way to know which one of the sensors has exceeded it’s high temperature threshold. In this example, one of the variable bindings for the netBotzTempTooHigh trap is netBotzV2TrapSensorID. These are variable bindings.Ī variable binding allows the device sending the SNMP trap to attach additional information to the trap. If you look at the netBotzTempTooHigh trap in the Zenoss web interface’s MIB explorer again, you’ll see that there’s an extensive list of Objects associated with the trap definition. Now that we’ve proved out a simple trap, we should add variable bindings or varbinds to the trap. oid: This is the original undecoded OID.eventClassKey: This should be netBotzTempTooHigh as decoded using the MIB.Sudo snmptrap 172.17.0.29 0 NETBOTZV2-MIB::netBotzTempTooHighįind this netBotzTempTooHigh event in web interface’s event console.ĭouble-click the “snmp trap netBotzTempTooHigh” event in the event console to see its details.

If you have stopped the zentrap service, or if you have it configured to manual launch mode, you will need to start it. Make sure the zentrap service is running. Use the following steps to get your feet wet sending a basic trap. We’ll now see information about this trap in the bottom-right panel. Choose netBotzTempTooHigh in the list of traps.Choose Traps from the drop-down box in the middle of the right panel.Choose NETBOTZV2-MIB from the list of MIBs.Let’s start by picking an SNMP trap to simulate. The alternative is breaking your real devices in various ways and hoping to be able to get the device to send all of the traps you need.

To more easily configure and test Zenoss’ trap handling, it’s useful to know how to simulate SNMP traps. Choose Add to ZenPack from the gear menu at the bottom of the list.Navigate to Advanced -> MIBs in the web interface.
