View file system resource usage, file system details - File Storage NAS

View storage usage by tier, performance metrics, mount status, and bandwidth for your NAS file systems from the console.

Query file system resource usage

The NAS console displays the storage usage of all file systems under the current account, categorized by storage type, including standard storage, Infrequent Access (IA) storage, Archive storage, and Recycle Bin capacity.

Note

The storage capacity displayed in the console is an estimated peak value of storage usage during the last clock hour and is not used as the billing basis. To query detailed metering data, see Resource usage and bills.

Query storage usage
- View in the file system list
  On the File systems page, drag the slider at the bottom of the list to reveal the Total Storage, Standard Storage, IA Storage Usage, Archive Storage Usage, and Recycle Bin Storage (Standard/IA) columns for each file system.
  - Total storage: The overall storage usage of the file system.
    - General-purpose NAS: The sum of standard storage usage and Infrequent Access (IA) storage usage.
    - Extreme NAS: The provisioned capacity of the file system.
  - Standard storage usage: The storage usage of active data in the file system. For General-purpose NAS, this also includes Recycle Bin storage (Standard/IA). This value is estimated based on the peak during the last clock hour.
  - Infrequent Access (IA) storage usage: The amount of cold data in General-purpose NAS that has been dumped to Infrequent Access (IA) storage.
  - Archive storage usage: The amount of cold data in General-purpose NAS that has been dumped to Archive storage.
  - Recycle Bin storage (Standard/IA): After the Recycle Bin is enabled, the storage usage of deleted files or directories temporarily stored in the Recycle Bin in General-purpose NAS.
- View on the file system details page
  On the File System list page, click the target file system ID to go to the details page, and view storage usage on the Basic Information tab.
Query Recycle Bin storage usage
On the Recycle Bin tab, you can view the Recycle Bin storage usage of the specified file system. For more information, see Recycle bin.
Note
When querying General-purpose NAS bills, the storage usage includes Capacity, Advanced, or Performance storage usage and Recycle Bin storage usage. For more information, see Resource usage and bills.

View the file system list

Log on to the NAS console.
In the left-side navigation pane, choose File System > File System List.
In the upper part of the page, select a region.
On the File System List page, view all file systems under your account in the current region.

View file system performance metrics

The Monitoring tab provides the following performance metrics, which can be used to diagnose file system performance issues:

Metric	Description
IOPS (input/output operations per second)	The read and write operation rate of the file system
Data throughput	The amount of data transferred per second

Log on to the NAS console.
In the left-side navigation pane, click File System > File System List.
In the upper part of the page, select a region.
On the File System List page, click the target file system ID.
On the file system details page, click Performance Monitoring.
On the Performance Monitoring tab, view performance metrics such as IOPS and data throughput.

Check the mount status of an ECS instance

Log on to the NAS console.
In the left-side navigation pane, choose File System > File System List.
In the top menu bar, select a region.
On the File System List page, click the file system ID that you want to query.
On the details page of the file system, click Mount Targets.
On the Mount Targets tab, click Mount in the Actions column of the target mount target.
In the Mount panel, click Query Mount Details in the Actions column of the target ECS instance to view the mount status of the ECS instance.

View file system throughput

Log on to the NAS console.
In the left-side navigation pane, choose File System > File System List.
In the top menu bar, select a region.
On the File System List page, click the ID of the file system that you want to query.
On the Basic Information tab, view the bandwidth information of the target file system.

View file content in a file system

The NAS console only displays metadata such as storage usage and performance metrics of file systems, and does not provide the ability to browse file content online. To view the specific files and directories stored in a file system, you need to mount the file system to an ECS instance and access the mount directory through the ECS instance to browse file content.

Linux ECS instance: After you mount an NFS file system to an ECS instance, you can browse files in the mount directory by using commands such as ls and cd. For specific mount operations, see Mount an NFS file system.
Windows ECS instance: After you mount an SMB file system to an ECS instance, you can browse files in the mapped network drive through File Explorer. For specific mount operations, see Mount an SMB file system.

After mounting is complete, the file and directory structure in the NAS file system is the same as that of a local file system. You can read, copy, or delete files just like operating a local disk. If you no longer need the file system, you can unmount it and delete the file system to stop billing. However, data cannot be recovered after deletion.
