Some disk monitoring metrics require the agent to be installed.
For details about how to install the Agent on an ECS, see Installing the Agent on a Linux Server in the Cloud Eye User Guide.
Table 1 Disk metrics | Metric | Parameter | Description | Value Range | Unit | Conversion Rule | Dimension | Monitoring Period (Raw Data) |
| disk_free | (Agent) Available Disk Space | Free space on the disks - 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 (-), periods (.), and tildes (~).
- 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 (-), periods (.), and tildes (~).
| ≥0 | GB | N/A | instance_id,mount_point | 1 minute |
| disk_total | (Agent) Disk Storage Capacity | Total space on the disks, including used and free - Linux: Run the df -h command to check the value in the Size column.

| disk_used | (Agent) Used Disk Space | Used space on the disks - 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 (-), periods (.), and tildes (~).

| ≥0 | GB | N/A | instance_id,mount_point | 1 minute |
| 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 - 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 (-), periods (.), and tildes (~).
