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.

Table 1 Disk metrics

Metric	Parameter	Description	Value Range	Monitored Object	Monitoring Period (Raw Data)
mountPointPrefix_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 (~).	>= 0	ECS	1 minute
mountPointPrefix_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 (~).	>= 0	ECS	1 minute
mountPointPrefix_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 (~).	>= 0	ECS	1 minute
mountPointPrefix_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 (~).	0-100	ECS	1 minute
