OS Monitoring Metrics Supported by ECSs with the Agent Installed

Description

This section describes monitoring metrics reported by ECSs to Cloud Eye as well as their namespaces and dimensions. You can use the Cloud Eye management console or APIs to obtain the monitoring metrics and alarms generated for ECSs.

After installing the agent on an ECS, you can view its OS monitoring metrics. Monitoring data is collected every 1 minute.

OS Monitoring Metrics

Table 1 OS monitoring metrics
Metric	Parameter	Description	Value Range	Monitored Object	Monitoring Period (Raw Data)
cpu_usage	(Agent) CPU Usage	CPU usage of the monitored object Unit: percent Linux: Check metric value changes in file /proc/stat in a collection period. Run the top command to check the %Cpu(s) value. Windows: Obtain the metric value using the Windows API GetSystemTimes.	0-100	ECS	1 minute
load_average5	(Agent) 5-Minute Load Average	CPU load averaged from the last 5 minutes Linux: Obtain the metric value from the number of logic CPUs in load5/ in file /proc/loadavg. Run the top command to check the load5 value. Windows does not support this metric.	≥ 0	ECS	1 minute
mem_usedPercent	(Agent) Memory Usage	Memory usage of the monitored object Unit: percent Linux: Obtain the metric value from the /proc/meminfo file: (MemTotal - MemAvailable)/MemTotal Windows: Obtain the value using the following formula: Used memory size/Total memory size x 100%	0-100	ECS	1 minute
mountPointPrefix_disk_free	(Agent) Available Disk Space	Free disk space Unit: GB 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 (-), dots (.), 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 (-), dots (.), and swung dashes (~).	≥ 0	ECS	1 minute
mountPointPrefix_disk_usedPercent	(Agent) Disk Usage	Percentage of total disk space that is used Unit: percent Linux: Obtain the metric value using following formula: Disk Usage = Used Disk Space/Disk Storage Capacity. The path of the device name prefix cannot exceed 64 characters. It must start with a letter, and contain only digits, letters, hyphens (-), dots (.), 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 (-), dots (.), and swung dashes (~).	0-100	ECS	1 minute
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: Obtain the metric value by calculating the data changes in the thirteenth column of the monitored object 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 (-), dots (.), and swung dashes (~). Windows does not support this metric.	0-100	ECS	1 minute
mountPointPrefix_disk_inodesUsedPercen	(Agent) Percentage of Total inode Used	Number of used index nodes on the disk Unit: percent Linux: Run the df -i command to check the value in the IUse% column. The path of the device name prefix cannot exceed 64 characters. It must start with a letter, and contain only digits, letters, hyphens (-), dots (.), and swung dashes (~). Windows does not support this metric.	0-100	ECS	1 minute
net_bitSent	(Agent) Inbound Bandwidth	Number of bits sent by the target NIC per second Unit: bit/s Linux: Check metric value changes in file /proc/net/dev in a collection period. Windows: Obtain the metric value using the WMI MibIfRow object.	≥ 0	ECS	1 minute
net_bitRecv	(Agent) Outbound Bandwidth	Number of bits received by the monitored object per second Unit: bit/s Linux: Check metric value changes in file /proc/net/dev in a collection period. Windows: Obtain the metric value using the WMI MibIfRow object.	≥ 0	ECS	1 minute
net_packetRecv	(Agent) NIC Packet Receive Rate	Number of packets received by this NIC per second Unit: count/s Linux: Check metric value changes in file /proc/net/dev in a collection period. Windows: Obtain the metric value using the WMI MibIfRow object.	≥ 0	ECS	1 minute
net_packetSent	(Agent) NIC Packet Send Rate	Number of packets sent by this NIC per second Unit: count/s Linux: Check metric value changes in file /proc/net/dev in a collection period. Windows: Obtain the metric value using the WMI MibIfRow object.	≥ 0	ECS	1 minute
net_tcp_total	(Agent) Total Number of TCP Connections	Total number of TCP connections of this NIC	≥ 0	ECS	1 minute
net_tcp_established	(Agent) Number of ESTABLISHED TCP Connections	Number of ESTABLISHED TCP connections of this NIC	≥ 0	ECS	1 minute
