Collector error on Data Migration Assistant when running assessment

Question

Hi,
I am running DMA on my local dev machine (as an admin), connecting to a locally installed SQL2019 instance, where I am also an SA. When I run an assessment on any database I receive the following error:

The server instance-level assessment of server 'MyServer' failed.  
Feature discovery error message: 'There was an unexpected exception when discovering features for server 'MyServer'.; Inner excreption message: Collector 'Microsoft.SqlServer.Advisor.Scenarios.FeatureDiscovery.Collectors.ServerPropertiesFeatureCollector' failed to collect data.'.  

I'm using the latest DMA tool, running as admin, with admin rights on machine and on SQL instance as mentioned. The localhost machine is a Windows 10 1909 system.

Looking at the DMA logs I can see:

Dma.exe Information: 0 : Completed Action: DiscoverFeaturesAssessmentAdvisor

Dma.exe Information: 0 : The step 'Completed' in activity '45f343d9-9875-4088-a8f1-d8b38ae69211' had a final outcome of 'Failed'  

As this is all running locally, with admin rights everywhere, I'm not sure what could be causing the issue so wondered if anyone from MSFT could advise?
Thanks,
Ben C

Answer 1

My suggestion is to disable any security software (antivirus, etc) that is preventing a Web Browser to pop up. A browser window is supposed to kick off at first, and some security extensions block that kind of activity.

Hi @Ben C ,

Please read this document first to check if there are any non-compliance.
