Table 1 AS metrics

Metric

Description

Formula

Description

CPU Usage

CPU usage (%) of an AS group

CPU usage of all instances in an AS group/Number of vCPUs of all instances in the AS group

N/A

Memory Usage

Memory usage (%) of an AS group

Used memory of all instances in an AS group/Total memory of all instances in the AS group

This metric is unavailable if the image has no OTC Tools installed.

Number of Instances

Number of available instances in an AS group

Total number of functional instances in an AS group

N/A

Inband Incoming Rate

Total number of functional instances in an AS group

(Total number of inband incoming bytes summarized over all instances in an AS group/Total number of instances in the AS group)/Monitoring period

N/A

Inband Outgoing Rate

Number of outgoing bytes summarized over the instances in an AS group per second

(Total number of inband outgoing bytes summarized over all instances in an AS group/Total number of instances in the AS group)/Monitoring period

N/A

Disks Read Rate

Number of bytes read from all instances in an AS group per second

(Total number of bytes read from all instances in an AS group/Total number of instances in the AS group)/Monitoring period

N/A

Disks Write Rate

Number of bytes written to all instances in an AS group per second

(Total number of bytes written to all instances in an AS group/Total number of instances in the AS group)/Monitoring period

N/A

Disks Read Requests

Number of read requests sent to all instances in an AS group per second

(Total number of read requests sent to all instances in an AS group/Total number of instances in the AS group)/Monitoring period

N/A

Disks Write Requests

Number of write requests sent to all instances in an AS group per second

(Total number of write requests sent to all instances in an AS group/Total number of instances in the AS group)/Monitoring period

N/A

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/.
  • For details about whether your OS supports the Memory Usage, Inband Outgoing Rate, and Inband Incoming Rate metrics, see Elastic Cloud Server User Guide.
