ECS Metrics

You do not need to install the Agent for the basic monitoring metrics of ECSs. You can view the basic monitoring metrics after you have created ECSs and the ECSs have been running for several minutes.

Basic monitoring metric data is reported every 5 minutes.

ECS metrics vary depending on ECS OSs and types. For details, see Table 1. √ indicates that the metric is supported, and x indicates that the metric is not supported.

**Table 1** Supported ECS metrics
Metric	Windows ECS	Linux ECS
CPU Usage	√	√
Memory Usage	√	×
Disk Usage	√	×
Disk Read Bandwidth	√	√
Disk Write Bandwidth	√	√
Disk Read IOPS	√	√
Disk Write IOPS	√	√
Inband Incoming Rate	√	×
Inband Outgoing Rate	√	×
Outband Incoming Rate	√	√
Outband Outgoing Rate	√	√

Table 2 describes these ECS metrics.

**Table 2** Basic metric description
Metric ID	Parameter	Description	Value Range	Monitored Object & Dimension	Monitoring Interval (Raw Metrics and KVM Only)
cpu_util	CPU Usage	CPU usage of an ECS Unit: Percent Formula: CPU usage of an ECS/Number of vCPUs in the ECS	≥ 0	ECS	5 minutes
mem_util	Memory Usage	Memory usage of an ECS This metric is unavailable if the image has no UVP VMTools installed. Unit: Percent Formula: Used memory of an ECS/Total memory of the ECS NOTE: The memory usage of QingTian ECSs cannot be monitored.	≥ 0	ECS	5 minutes
disk_util_inband	Disk Usage	Disk usage of an ECS This metric is unavailable if the image has no UVP VMTools installed. Unit: Percent Formula: Used capacity of an ECS-attached disk/Total capacity of the ECS-attached disk	≥ 0	ECS	5 minutes
disk_read_bytes_rate	Disk Read Bandwidth	Number of bytes read from an ECS-attached disk per second Unit: byte/s Formula: Total number of bytes read from an ECS-attached disk/Monitoring interval byte_out = (rd_bytes - last_rd_bytes)/Time difference	≥ 0	ECS	5 minutes
disk_write_bytes_rate	Disk Write Bandwidth	Number of bytes written to an ECS-attached disk per second Unit: byte/s Formula: Total number of bytes written to an ECS-attached disk/Monitoring interval	≥ 0	ECS	5 minutes
disk_read_requests_rate	Disk Read IOPS	Number of read requests sent to an ECS-attached disk per second Unit: request/s Formula: Total number of read requests sent to an ECS-attached disk/Monitoring interval req_out = (rd_req - last_rd_req)/Time difference	≥ 0	ECS	5 minutes
disk_write_requests_rate	Disk Write IOPS	Number of write requests sent to an ECS-attached disk per second Unit: request/s Formula: Total number of write requests sent to an ECS-attached disk/Monitoring interval req_in = (wr_req - last_wr_req)/Time difference	≥ 0	ECS	5 minutes
network_incoming_bytes_rate_inband	Inband Incoming Rate	Number of incoming bytes on an ECS per second Unit: byte/s Formula: Total number of inband incoming bytes on an ECS/Monitoring interval	≥ 0	ECS	5 minutes
network_outgoing_bytes_rate_inband	Inband Outgoing Rate	Number of outgoing bytes on an ECS per second Unit: byte/s Formula: Total number of inband outgoing bytes on an ECS/Monitoring interval	≥ 0	ECS	5 minutes
network_incoming_bytes_aggregate_rate	Outband Incoming Rate	Number of incoming bytes on an ECS per second on the hypervisor Unit: byte/s Formula: Total number of outband incoming bytes on an ECS/Monitoring interval This metric is unavailable if SR-IOV is enabled.	≥ 0	ECS	5 minutes
network_outgoing_bytes_aggregate_rate	Outband Outgoing Rate	Number of outgoing bytes on an ECS per second on the hypervisor Unit: byte/s Formula: Total number of outband outgoing bytes on an ECS/Monitoring interval This metric is unavailable if SR-IOV is enabled.	≥ 0	ECS	5 minutes
