Creates or modifies an alert rule for an application group.
This topic provides an example to create an alert rule for the cpu_total metric of Elastic Compute Service (ECS) in the 17285**** application group. The ID of the alert rule is 123456. The name of the alert rule is Rule_test. The alert level is Critical. The statistical method is Average. The alert threshold comparator is GreaterThanOrEqualToThreshold. The alert threshold is 90. The number of alert retries is 3. The returned result shows that the alert rule is created and the alert rule ID is
123456.

Request parameters
| Parameter | Type | Required | Example | Description |
|---|---|---|---|---|
| Action | String | Yes | PutGroupMetricRule |
The operation that you want to perform. Set the value to PutGroupMetricRule. |
| Category | String | Yes | ECS |
The name of the cloud service. Valid values:
|
| GroupId | String | Yes | 17285**** |
The ID of the application group. For information about how to obtain the ID of an application group, see DescribeMonitorGroups. |
| MetricName | String | Yes | cpu_total |
The name of the metric. For information about how to obtain the name of a metric, see DescribeMetricMetaList or Metrics. |
| Namespace | String | Yes | acs_ecs_dashboard |
The namespace of the cloud service. For information about how to obtain the namespace of a cloud service, see DescribeMetricMetaList or Metrics. |
| RuleId | String | Yes | 123456 |
The ID of the alert rule.
|
| RuleName | String | Yes | Rule_01 |
The name of the alert rule.
|
| Dimensions | String | No | [{"instanceId":"i-m5e1qg6uo38rztr4****"}] |
The first-level dimension of the alert rule in the application group. Set the value to a set of key-value pairs, for example, |
| ExtraDimensionJson | String | No | {"/dev/xvda":"d-m5e6yphgzn3aprwu****"} |
The second-level or third-level dimension of the alert rule in the application group. Set the value to a set of key-value pairs, for example, If the first-level dimension of the alert rule is |
| EffectiveInterval | String | No | 05:31-23:59 |
The time period during which the alert rule is effective. |
| NoEffectiveInterval | String | No | 00:00-05:30 |
The time period during which the alert rule is ineffective. |
| SilenceTime | Integer | No | 86400 |
The mute period during which new alerts are not sent even if the trigger conditions are met. Unit: seconds. Default value: 86400. |
| Period | String | No | 60 |
The aggregation period of the metric data. Set the |
| Interval | String | No | 60 |
The interval at which CloudMonitor checks whether the alert rule is triggered. Unit: seconds. Note We recommend that you set the interval to the data aggregation period. If the interval
is shorter than the data aggregation period, alerts cannot be triggered due to insufficient
data.
|
| Webhook | String | No | https://www.aliyun.com |
The callback URL. The callback URL must be accessible over the Internet. CloudMonitor pushes an alert notification to the specified callback URL by sending an HTTP POST request. Only the HTTP protocol is supported. |
| EmailSubject | String | No | ECS instance |
The subject of the alert notification email. |
| ContactGroups | String | No | ECS_Group |
The contact groups that receive alert notifications. |
| Escalations.Critical.Statistics | String | No | Average |
The statistical methods for Critical-level alerts. Separate multiple statistical methods with commas (,). Valid values:
|
| Escalations.Critical.ComparisonOperator | String | No | GreaterThanOrEqualToThreshold |
The comparison operator of the threshold for Critical-level alerts. Valid values:
|
| Escalations.Critical.Threshold | String | No | 90 |
The threshold for Critical-level alerts. |
| Escalations.Critical.Times | Integer | No | 3 |
The consecutive number of times for which the metric value is measured before a Critical-level alert is triggered. |
| Escalations.Warn.Statistics | String | No | Average |
The statistical methods for Warn-level alerts. Separate multiple statistical methods with commas (,). Valid values:
|
| Escalations.Warn.ComparisonOperator | String | No | GreaterThanOrEqualToThreshold |
The comparison operator of the threshold for Warn-level alerts. Valid values:
|
| Escalations.Warn.Threshold | String | No | 90 |
The threshold for Warn-level alerts. |
| Escalations.Warn.Times | Integer | No | 3 |
The consecutive number of times for which the metric value is measured before a Warn-level alert is triggered. |
| Escalations.Info.Statistics | String | No | Average |
The statistical methods for Info-level alerts. Separate multiple statistical methods with commas (,). Valid values:
|
| Escalations.Info.ComparisonOperator | String | No | GreaterThanOrEqualToThreshold |
The comparison operator of the threshold for Info-level alerts. Valid values:
|
| Escalations.Info.Threshold | String | No | 90 |
The threshold for Info-level alerts. |
| Escalations.Info.Times | Integer | No | 3 |
The consecutive number of times for which the metric value is measured before an Info-level alert is triggered. |
| NoDataPolicy | String | No | KEEP_LAST_STATE |
The processing method of alerts when no monitoring data is found. Valid values:
