Duplicate entries are found for metrics in the UIM database

Issue/Introduction

Checking the database data_engine logs shows two duplicate entries for each of these metrics (timestamp, value, nimid, etc are all replicated):

RN tables show duplicate entries: 

DrNimbus only shows one QOS_MESSAGE in the queues on the primary hub.

This occurs for metrics from many, if not all, robots.

Environment

• UIM 23.4

Cause

This issue can be caused by having more than one queue between hubs for the QOS_MESSAGE subject.  This causes the message to be duplicated, but DrNimbus will only show one QOS_MESSAGE in the queues on the primary hub.  

Resolution

• Identify the hubs where you have more than one queue with the QOS_MESSAGE subject.
  • Note that the wildcard * subject will also have the QOS_MESSAGE subject included
  • If you have a multi-tiered hub structure, you may need to check the entire path from the affected robots to the primary hub (or hub where the data_engine is running).
• Deactivate the attach and get queues on both of the hubs.
  • Delete these queues when you confirm the problem is resolved.
