Inventory output
Each inventory rule generates a set of files in the specified inventory destination container for that rule. The inventory output is generated under the following path: https://<accountName>.blob.core.windows.net/<inventory-destination-container>/YYYY/MM/DD/HH-MM-SS/<r... where:
- accountName is your Azure Blob Storage account name.
- inventory-destination-container is the destination container you specified in the inventory rule.
- YYYY/MM/DD/HH-MM-SS is the time when the inventory began to run.
- ruleName is the inventory rule name.
