How Can I Monitor My Disk Usages?

Some disk monitoring metrics require that the agent to be installed.

  • For instructions about how to install the agent on a Windows ECS, see "Installing and Configuring the Agent (Windows)" in the Cloud Eye User Guide.
  • For instructions about how to install the agent on a Linux ECS, see "Installing and Configuring the Agent (Linux)" in the Cloud Eye User Guide.

disk_free

(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 (~).
