How Can I Monitor My Disk Usages?

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" in the Cloud Eye User Guide.

Table 1 Disk metrics
Metric	Parameter	Description	Value Range	Monitored Object & Dimension	Monitoring Period (Raw Data)
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 (-), periods (.), 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 (-), periods (.), and swung dashes (~).	≥ 0	ECS - Mount point	1 minute
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 (-), periods (.), 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 (-), periods (.), and swung dashes (~).	≥ 0	ECS - Mount point	1 minute
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 (-), periods (.), 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 (-), periods (.), and swung dashes (~).	≥ 0	ECS - 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 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 (-), periods (.), 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 (-), periods (.), and swung dashes (~).	0-100	ECS - Mount point	1 minute
