SNMP trap

Monitor description

The monitor receives trap messages from SNMP monitors on remote hosts. The monitor only receives messages that originate from the object's IP address. The first step of the filtering is done with the specified enterprise OIDs. Further inspection of the trap is done with the variable binding filter, which can include several rules. The rules are either evaluated all together (AND operation) or one by one (OR operation). The resulting trap triggers a failed test. The monitor can filter out standard generic SNMP v1 trap types.

Each OID field can be populated by selecting it from the MIB browser. The MIB browser is opened by pressing the button to the right of the OID field.
