Basic ECS Metrics

Basic ECS metrics vary depending on ECS OSs and types. For details, see Table 1.

Certain ECS metrics require the installation of UVP VMTools on the image from which the ECS is created. For details about how to install UVP VMTools, see https://github.com/UVP-Tools/UVP-Tools/.

Table 2 describes these basic ECS metrics.

The monitoring intervals for the following ECSs with raw monitoring metrics are as follows:

Xen ECSs: 4 minutes
KVM ECSs: 5 minutes

**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
network_vm_connections	Network Connections	Total number of TCP and UDP connections to an ECS Unit: count NOTE: This metric is collected out-of-band and its value may be greater than the number of network connections queried in the OS.	≥ 0	ECS	5 minutes
network_vm_bandwidth_in	Inbound Bandwidth	Number of public and private bits received by the ECS per second Unit: byte/s	≥ 0	ECS	5 minutes
network_vm_bandwidth_out	Outbound Bandwidth	Number of public and private bits sent by the ECS per second Unit: byte/s	≥ 0	ECS	5 minutes
network_vm_pps_in	Inbound PPS	Number of public and private packets received by the ECS per second Unit: packet/s	≥ 0	ECS	5 minutes
network_vm_pps_out	Outbound PPS	Number of public and private packets sent by the ECS per second Unit: packet/s	≥ 0	ECS	5 minutes
network_vm_newconnections	New Connections	Number of new connections (including TCP, UDP, and ICMP) created on the ECS Unit: count	≥ 0	ECS	5 minutes
inst_sys_status_error	System Status Check Failed	Status of the cloud platform for running ECSs, which can be 0 or 1 0: The system is running properly. All check items are normal. 1: The system is not running properly. At least one check item failed. When the power source of the physical server fails or the hardware/software becomes faulty, the check result is 1. The system periodically checks the status and returns check results using value 0 or 1. If the detected fault does not affect ECS functions, certain management operations performed on the ECS, such as starting, stopping, or specifications modifications, may be affected. If the detected fault affects ECS functions, such as a server power supply failure, the system will recover the ECS as soon as possible.	0 or 1	ECS	5 minutes
