4. Example

Example1 Creating a target tracking policy for average CPU utilization

The following policy keeps the average CPU utilization of the scaling group stay around 60%, warms up instances added for scale-out for 300 seconds, and allows scale-in.

Input Example

POST / HTTP/1.1
Host: as.tencentcloudapi.com
Content-Type: application/json
X-TC-Action: CreateScalingPolicy
<Common request parameters>

{
    "AutoScalingGroupId": "asg-9dn1a5y6",
    "ScalingPolicyName": "cpu_target_tracking_test",
    "ScalingPolicyType": "TARGET_TRACKING",
    "PredefinedMetricType": "ASG_AVG_CPU_UTILIZATION",
    "EstimatedInstanceWarmup": 300,
    "DisableScaleIn": false,
    "TargetValue": 60
}

Output Example

{
    "Response": {
        "AutoScalingPolicyId": "asp-ljr51ssq",
        "RequestId": "58a8ac17-e864-4bf6-81c7-c5dc63b0057d"
    }
}

Example2 Creating a simple policy for average CPU utilization

This example shows you how to increase the desired capacity by one if the average CPU utilization is over 50% within 1 minute for 5 consecutive occurrences.

Input Example

POST / HTTP/1.1
Host: as.tencentcloudapi.com
Content-Type: application/json
X-TC-Action: CreateScalingPolicy
<Common request parameters>

{
    "AutoScalingGroupId": "asg-12wjuh0s",
    "Cooldown": "60",
    "ScalingPolicyType": "SIMPLE",
    "ScalingPolicyName": "cpu_policy_test",
    "AdjustmentType": " CHANGE_IN_CAPACITY",
    "MetricAlarm": {
        "Period": "60",
        "ContinuousTime": "5",
        "ComparisonOperator": "GREATER_THAN",
        "Statistic": "AVERAGE",
        "Threshold": "50",
        "MetricName": "CPU_UTILIZATION"
    },
    "NotificationUserGroupIds": [
        "1678"
    ],
    "AdjustmentValue": "1"
}

Output Example

{
    "Response": {
        "AutoScalingPolicyId": "asp-iir70sxv",
        "RequestId": "fb02c8bd-5f38-4786-91b6-0c6e06a88832"
    }
}

Example3 Creating a simple policy for average MEM utilization

This example shows you how to decrease the capacity by 50% if the average MEM utilization is below 35% within 1 minute for 5 consecutive occurrences.

Input Example

POST / HTTP/1.1
Host: as.tencentcloudapi.com
Content-Type: application/json
X-TC-Action: CreateScalingPolicy
<Common request parameters>

{
    "AutoScalingGroupId": "asg-12wjuh0s",
    "Cooldown": "300",
    "ScalingPolicyType": "SIMPLE",
    "ScalingPolicyName": "mem_policy_test",
    "AdjustmentType": " PERCENT_CHANGE_IN_CAPACITY",
    "MetricAlarm": {
        "Period": "60",
        "ContinuousTime": "5",
        "ComparisonOperator": "LESS_THAN",
        "Statistic": "AVERAGE",
        "Threshold": "50",
        "MetricName": "MEM_UTILIZATION"
    },
    "NotificationUserGroupIds": [
        "1678"
    ],
    "AdjustmentValue": "-50"
}

Output Example

{
    "Response": {
        "AutoScalingPolicyId": "asp-f59pppuh",
        "RequestId": "116213d6-2269-44cc-af76-c4a8dc7dbdf9"
    }
}
