Basic ECS Metrics

Description

This section describes basic monitoring metrics reported by ECS to Cloud Eye. You can use Cloud Eye to view these metrics and alarms generated for ECSs.

Basic ECS Metrics

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

**Table 1** Basic ECS metrics
Metric	Windows	Linux
CPU Usage	Supported	Supported
Memory Usage	Supported	Not supported
Disk Usage	Supported	Not supported
Disk Read Bandwidth	Supported	Supported
Disk Write Bandwidth	Supported	Supported
Disk Read IOPS	Supported	Supported
Disk Write IOPS	Supported	Supported
Inband Incoming Rate	Supported	Not supported
Inband Outgoing Rate	Supported	Not supported
Outband Incoming Rate	Supported	Supported
Outband Outgoing Rate	Supported	Supported

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
