To check where the bulk of the QOS is being generated from (which probes' QOS objects), you can click the data_engine "Status" button but it is not delivering any results in the data_engine probe GUI Status window. It is empty/blank.
This works just fine in MS SQL Server v2016 in the lab but not in the customer's environment which is running MS SQL Server v2019:
Microsoft SQL Server 2019 (RTM-CU20) (KB5024276) - 15.0.4312.2 (X64) Apr 1 2023 12:10:46 Copyright (C) 2019 Microsoft Corporation Enterprise Edition: Core-based Licensing (64-bit) on Windows Server 2019 Standard 10.0 <X64> (Build 17763: ) (Hypervisor)
SMSS error message result:
Msg 245, Level 16, State 1, Line 25
Conversion failed when converting the nvarchar value 'sysrscols' to data type int.
>>>sysrscols is a hidden system table which is used for tracking the column modification.
Confirmed this updated version of the underlying query for the data_engine Status button is working as expected in MS SQL Server 2019 in the UIM monitoring environment.
When run manually, you must run the create table first then the select.
