AS Metrics

This section describes the monitoring metrics reported by AS to Cloud Eye and defines the namespace for the metrics. You can use Cloud Eye to query metrics and alarms generated by AS.

**Table 1** AS metrics
Metric ID	Metric	Description	Value Range	Monitored Object	Monitoring Interval (Raw Data)

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
