This section describes the SNMP collection agents. These agents are available in real-time workflow configurations. The SNMP Collection profile is used to import the set of MIB files that will be used to build the target UDRs. To poll the network, the SNMP Request agent periodically sends queries to the devices (network elements) on the network. These queries determine the behavior of the devices, for example, operational status, or the data in the MIB variables of the devices. The UDR types and fields to poll can either be configured directly in the SNMP Request agent, or in a separate SNMP OID profile, that can be referenced by several SNMP Request agents.
The SNMP Request agent produces a user-configured UDR as a result of SNMP polling. For the user convenience, the target UDR follows the hierarchical structure of MIB Object definitions. The SNMP Trap agent is used to receive SNMP notifications (traps and informs). The SNMP Trap agent produces and maps SNMP notifications to UDRs, so they can be further processed by the Platformby the Platform.
