**Table 1** AS metrics
Metric ID	Metric	Description	Value Range	Monitored Object	Monitoring Interval (Raw Data)
cpu_util	CPU Usage	CPU usage of an AS group Formula: Total CPU usage of all ECS instances in an AS group/Number of ECS instances in the AS group Unit: Percent	≥0%	AS group	5 minutes
mem_util	Memory Usage	Memory usage of an AS group Formula: Total memory usage of all ECS instances in an AS group/Number of ECS instances in the AS group Unit: Percent NOTE: This metric is unavailable if the image has no VM Tools installed.	≥0%	AS group	5 minutes
instance_num	Number of Instances	Number of available ECS instances in an AS group Formula: Total number of ECS instances in Enabled state in the AS group	≥0	AS group	5 minutes
network_incoming_bytes_rate_inband	Inband Incoming Rate	Number of incoming bytes per second on an ECS in an AS group Formula: Total inband incoming rate of all ECS instances in an AS group/Number of ECS instances in the AS group Unit: Byte/s	≥0 Byte/s	AS group	5 minutes
network_outgoing_bytes_rate_inband	Inband Outgoing Rate	Number of outgoing bytes per second on an ECS in an AS group Formula: Total inband outgoing rate of all ECS instances in an AS group/Number of ECS instances in the AS group Unit: Byte/s	≥0 Byte/s	AS group	5 minutes
disk_read_bytes_rate	Disks Read Rate	Number of bytes read from an AS group per second Formula: Total disk read rate of all ECS instances in an AS group/Number of ECS instances in the AS group Unit: Byte/s	≥0 Byte/s	AS group	5 minutes
disk_write_bytes_rate	Disks Write Rate	Number of bytes written to an AS group per second Formula: Total disk write rate of all ECS instances in an AS group/Number of ECS instances in the AS group Unit: Byte/s	≥0 Byte/s	AS group	5 minutes
disk_read_requests_rate	Disks Read Requests	Number of read requests per second sent to an ECS disk in an AS group Formula: Total number of disk read requests of all ECS instances in an AS group/Number of ECS instances in the AS group Unit: Request/s	≥0 request/s	AS group	5 minutes
disk_write_requests_rate	Disks Write Requests	Number of write requests per second sent to an ECS disk in an AS group Formula: Total number of disk write requests of all ECS instances in an AS group/Number of ECS instances in the AS group Unit: Request/s	≥0 request/s	AS group	5 minutes

OSs determine whether the Memory Usage, Inband Outgoing Rate, and Inband Incoming Rate metrics are supported. For details, see Elastic Cloud Server User Guide.
