Some disk monitoring metrics require that the agent to be installed.
For details about how to install the Agent on an ECS, see section "Installing and Configuring the Agent on a Linux ECS or BMS" in the Cloud Eye User Guide.

(Agent) Available Disk Space |
Free space on the disks Unit: GB
- Linux: Run the df -h command to check the value in the Avail column. The path of the mount point prefix cannot exceed 64 characters. It must start with a letter, and contain only digits, letters, hyphens (-), dots (.), and swung dashes (~).
- Windows: Use the WMI interface to call GetDiskFreeSpaceExW API to obtain disk space data. The path of the mount point prefix cannot exceed 64 characters. It must start with a letter, and contain only digits, letters, hyphens (-), dots (.), and swung dashes (~).

disk_total |
(Agent) Disk Storage Capacity |
Total space on the disks, including used and free Unit: GB
- Linux: Run the df -h command to check the value in the Size column.
The path of the mount point prefix cannot exceed 64 characters. It must start with a letter, and contain only digits, letters, hyphens (-), dots (.), and swung dashes (~).
- Windows: Use the WMI interface to call GetDiskFreeSpaceExW API to obtain disk space data. The path of the mount point prefix cannot exceed 64 characters. It must start with a letter, and contain only digits, letters, hyphens (-), dots (.), and swung dashes (~).

disk_used |
(Agent) Used Disk Space |
Used space on the disks Unit: GB
- Linux: Run the df -h command to check the value in the Used column. The path of the mount point prefix cannot exceed 64 characters. It must start with a letter, and contain only digits, letters, hyphens (-), dots (.), and swung dashes (~).
- Windows: Use the WMI interface to call GetDiskFreeSpaceExW API to obtain disk space data. The path of the mount point prefix cannot exceed 64 characters. It must start with a letter, and contain only digits, letters, hyphens (-), dots (.), and swung dashes (~).

disk_usedPercent |
(Agent) Disk Usage |
Percentage of total disk space that is used, which is calculated as follows: Disk Usage = Used Disk Space/Disk Storage Capacity Unit: percent
- Linux: It is calculated as follows: Used/Size. The path of the mount point prefix cannot exceed 64 characters. It must start with a letter, and contain only digits, letters, hyphens (-), dots (.), and swung dashes (~).
- Windows: Use the WMI interface to call GetDiskFreeSpaceExW API to obtain disk space data. The path of the mount point prefix cannot exceed 64 characters. It must start with a letter, and contain only digits, letters, hyphens (-), dots (.), and swung dashes (~).
