Apologies for the delayed response. Data for Azure Files is stored in the StorageFileLogs table. You can perform queries to this table to get some performance data, samples can be found here. Since you are looking at performance the DurationMs and ServerLatencyMs would be useful to you, you can view the data that is logged here.
Since you are monitoring performance the Metrics in Azure Monitor will also be useful. A list of available metrics can be found here.
Hope this helps! Let us know if you run into issues or have further questions.
