    Well, the your guys are out of luck, the solution being pursued is highly specific and circumvents standard integration paths

     

    Key Findings: 
    #1. Application Insights telemetry is stored in a Log Analytics workspace, and querying it requires access via Azure Monitor or Azure Data Explorer,  in other words, YOU CAN'T READ directly from App. Insights but ONLY VIA og Analytics workspace (just want to make that clear) 

    #2.  Managed Identity authentication is "supported" for querying Log Analytics via Azure Monitor APIs, but this requires 

    a) Proper RBAC role assignment (e.g., Monitoring Reader).
    b) Use of supported libraries and endpoints (e.g., azure.monitor.query or Kusto SDK) 

    #3. Fabric workspace identity is limited to OneLake shortcuts, pipelines, semantic models, or Dataflows Gen2. (Ref. Authenticate with Microsoft Fabric workspace identity - Microsoft Fabric | Microsoft Learn

     

    Best of lucks 

     

    Sorry to be the bearer of bad news, if you find a solution to this case, let me know! But I recommend revisiting the architecture with supported ingestion methods.

     

    Hopefully, the outcome won't prevent from you to acnoldge the help provided thus far with a thumbs up 👍
