@Andy YOU

I have tried following that forum solutions, from the logs created all I can see is stats of what is being written, I cannot see the actual data being written.

Would you be able to DM me for a support call please?

Answer 1

@SenhorDolas
From the Azure File Share standpoint you can enable logging of StorageWrite operations by creating a diagnostic setting. You can access resource logs either as a blob in a storage account, as event data, or through Log Analytic queries. This should give you an idea what what files are being written. For a list of fields in the log you can refer to this page.

I will let the FSlogix experts chime in from their standpoint. Hope this helps. Let me know if you have further questions or issues.

Is there a way to get a support call opened?

Thanks, M

Thanks for the direction. I will try the diagnostic setting see what I get.
I would really need to know which metric to monitor?
