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 VM 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 |

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