Monitoring Metrics¶
Table 1 lists the AS metrics supported by Cloud Eye.
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 OTC 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 disk read requests sent to an AS group per second Formula: Total number of disk read requests sent to 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 disk write requests sent to an AS group per second Formula: Total number of disk write requests sent to 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 |
Note
The image based on which the target ECS is created must have OTC Tools installed. Otherwise, Memory Usage will be unavailable. For details about how to install the OTC Tools, visit https://github.com/UVP-Tools/UVP-Tools/.
OSs determine whether the Memory Usage, Inband Outgoing Rate, and Inband Incoming Rate metrics are supported. For details, see Elastic Cloud Server User Guide.
