Viewing EVS Monitoring Data Included in OS Metrics (with Agent Installed)

Description

This section describes the EVS-related metrics included in the OS metrics supported by ECS. The agent of the latest version is used with simplified monitoring metrics.

After installing the agent on an ECS, you can view its EVS-related metrics included in the OS monitoring metrics.

For instructions about how to install and configure the agent, see section "Agent Installation and Configuration" in the Cloud Eye User Guide.

Monitoring Metrics

Table 1 EVS-related metrics
Metric	Name	Description	Value Range	Monitored Object	Monitoring Period
mountPointPrefix_disk_free	(Agent) Available Disk Space	Available disk space on the monitored object Unit: GiB Linux: Run the df -h command to check the value in the Avail column. The path of the device name prefix cannot exceed 64 characters. It must start with a letter, and contain only digits, letters, hyphens (-), periods (.), and swung dashes (~). Windows: Obtain the metric value using the WMI API GetDiskFreeSpaceExW. The path of the device name prefix cannot exceed 64 characters. It must start with a letter, and contain only digits, letters, hyphens (-), periods (.), and swung dashes (~).	≥0 GiB	ECS	5 minutes in average
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 Capacity. Unit: Percent Linux: Obtain the metric value using the following formula: Disk Usage = Used Disk Space/Disk Capacity. The path of the device name prefix cannot exceed 64 characters. It must start with a letter, and contain only digits, letters, hyphens (-), periods (.), and swung dashes (~). Windows: Obtain the metric value using the WMI API GetDiskFreeSpaceExW. The path of the device name prefix cannot exceed 64 characters. It must start with a letter, and contain only digits, letters, hyphens (-), periods (.), and swung dashes (~).	0-100%	ECS	5 minutes in average
mountPointPrefix_disk_ioUtils and volumePrefix_disk_ioUtils	(Agent) Disk I/O Usage	Percentage of the time that the disk has had I/O requests queued to the total disk operation time Unit: Percent Linux: The disk I/O usage is calculated based on the data changes in the thirteenth column of the corresponding device in file /proc/diskstats in a collection period. The path of the device name prefix cannot exceed 64 characters. It must start with a letter, and contain only digits, letters, hyphens (-), periods (.), and swung dashes (~). Windows does not support this metric.	0-100%	ECS	5 minutes in average
