Duration: starting 10/30/2020 expected end date at 11/12/2020.
Impact: Due to upgrade in Azure Monitor for containers experience. Users will not be able to access “Container Insights Data Usage” workbook via Azure Monitor for containers workbook gallery(Workbooks entry point in left side of portal.)

Mitigation: Users can access workbook via View workbook menu drop-down.

Let us know if you have any question!
