SolarWinds Updated Hybrid-Cloud-Observability-Network-Monitoring Exam Questions and Answers by asees

Universal Device Pollers (UDPs) are tied to the polling engine on which they are created. This means if a UDP is created on the main polling engine, it will only collect data for devices polled by that engine. To collect data from devices polled by an additional polling engine, you must create or assign the UDP on that engine as well.

Exact Extract from Official Guide:

“Universal Device Pollers are tied to the polling engine on which they are created. To monitor devices assigned to an Additional Polling Engine, the UDP must be created or assigned on that engine.”

Comprehensive and Detailed Explanation From Exact Extract:

The most common cause of mismatch between bandwidth (SNMP) numbers and flow (NetFlow, sFlow, etc.) numbers is that not all network traffic is included in the flow export. SNMP bandwidth counters include all traffic traversing the interface, but NetFlow or other flow records may only represent sampled or filtered subsets, or may miss certain traffic due to export or device configuration limitations. This is a well-documented and expected difference in the SolarWinds platform.
