The SNMP Query operation on a pattern for a custom device query allows Discovery to retrieve information from the target device using the SNMP protocol. It is best practice to use the published manufacturer's device MIB, which is the official and standard definition of the device's SNMP data. Using the manufacturer's device MIB ensures that the query is accurate, consistent, and compatible with the device. Modifying the default MIB information, enabling SSH as a secondary protocol, or using live devices in production are not recommended practices, as they may introduce errors, security risks, or performance issues123.
