The Universal Device Poller (UnDP) is a feature that allows users to create custom monitors for almost any statistic provided by SNMP based on its Management Information Base (MIB) and object identifier (OID). However, sometimes the OID that the user wants to monitor may not be available in the MIB tree, either because it is not supported by the device or because the MIB database is outdated. In this case, the user needs to update the MIB database to get the latest MIBs from the SolarWinds website or from the device vendor. This will ensure that the UnDP canfind the OID in the MIB tree and poll it successfully12. References: 1: Update the SolarWinds MIB Database for the SolarWinds Platform3, 2: Monitor custom statistics based on OIDs with Universal Device Pollers in the SolarWinds Platformhttps://documentation.solarwinds.com/en/success_center/orionplatform/content/core-downloading-the-solarwinds-mib-database-sw3581.htm
