   Table 1 Parameters for configuring a bucket inventory

   Parameter	Description
   Inventory Name	Name of a bucket inventory
   Filter	Filtering condition of an inventory. You can enter an object name prefix, then the inventory generated will cover objects whose names begin with the same prefix. An inventory can only filter objects by a specified prefix. If the filter is not specified, the inventory covers the entire bucket. If a bucket has multiple inventories, overlaps between the inventory filters are not allowed.
   Save Inventory Files To	Select a bucket where the generated inventory files are stored. This bucket and the source bucket must be in the same region.
   Inventory File Name Prefix	Prefix of the storage path of the inventory files. Once an inventory file is generated, its saving path is in the following format: Inventory file name prefix/Source bucket name/Inventory name/Date and time/files/ If this parameter is not specified, the system automatically adds the prefix BucketInventory to an inventory file.
   Frequency	The frequency when inventory files are generated. It can be set to Daily or Weekly.
   Status	Status of the configured inventory. You can enable or disable it to make the configuration effective or ineffective.
