Monitoring Metrics

Description

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 monitoring metrics and alarms generated by AS.

Monitoring metrics

Table 1 lists the AS metrics supported by Cloud Eye.

**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

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 rates 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 rates 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 disks write rates 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 disks read rates 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 disks write rates 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
cpu_usage	(Agent) CPU Usage	Agent CPU usage of an AS group Formula: Total Agent CPU usage of all ECS instances in an AS group/Number of ECS instances in the AS group Unit: Percent	0-100%	AS group	1 minute
mem_usedPercent	(Agent) Memory Usage	Agent memory usage of an AS group Formula: Total Agent memory usage of all ECS instances in an AS group/Number of ECS instances in the AS group Unit: Percent	0-100%	AS group	1 minute
load_average1	(Agent) 1-Minute Load Average	Average CPU load of all ECSs in an AS group in the last 1 minute Unit: none	≥0	AS group	1 minute
load_average5	(Agent) 5-Minute Load Average	Average CPU load of all ECSs in an AS group in the last 5 minutes Unit: none	≥0	AS group	1 minute
load_average15	(Agent) 15-Minute Load Average	Average CPU load of all ECSs in an AS group in the last 15 minutes Unit: none	≥0	AS group	1 minute
gpu_usage_gpu	(Agent) GPU Usage	Agent GPU usage of an AS group Formula: Total Agent GPU usage of all ECS instances in an AS group/Number of ECS instances in the AS group Unit: Percent	0-100%	AS group	1 minute
gpu_usage_mem	(Agent) Video Memory Usage	Agent GPU memory usage of an AS group Formula: Total Agent GPU memory usage of all ECS instances in an AS group/Number of ECS instances in the AS group Unit: Percent	0-100%	AS group	1 minute

Monitoring metrics are classified into metrics with Agent and without Agent. For some OSs, you need to install the Agent to obtain the corresponding monitoring metrics. In this case, select the monitoring metrics with Agent, for example, (Agent) Memory Usage.

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

Before using Agent monitoring metrics, make sure that the Agent has been installed on the instances in the AS group. For details, see How Do I Install the Agent Plug-in on the Instances in an AS Group to Use Agent Monitoring Metrics?
