Properties
Property | Type | Required | Editable | Description | Constraint |
---|---|---|---|---|---|
NoEffectiveInterval | String | No | Yes | The time period during which the alert rule does not take effect. | None |
SilenceTime | Integer | No | Yes | The time period during which you do not receive notifications but the triggered alert remains effective. | Unit: seconds.
Minimum value: 3600. This value is equivalent to one hour. Default value: 86400. This value is equivalent to one day. |
Category | String | Yes | No | The abbreviation of the service name. | Valid values:
Note More Alibaba Cloud services are to be supported in the future.
|
RuleId | String | Yes | No | The ID of the alert rule. | The rule ID is generated by the caller to make sure that it is unique. |
Dimensions | String | No | Yes | The expended resource dimensions. | This parameter associates all instances in the application group with the alert rule.
You can set this parameter to associate lower-level resources with the alert rule.
For example, if you need to associate the disk usage of root partitions of all instances
in the application group with the alert rule, set this parameter to [ {"dskName":"/"} ] .
|
Period | Integer | No | Yes | The aggregation period of monitoring data. | The value is an integral multiple of 60.
Unit: seconds. Default value: 300. Note Assume that raw monitoring data is reported at an interval of 1 minute. If you set
this parameter to 300, the average of the 5-minute monitoring data is used to determine
whether to trigger an alert.
|
EffectiveInterval | String | No | Yes | The time period during which the alert rule is effective. | None |
Namespace | String | Yes | No | The namespace of the service. For more information, see DescribeMetricMetaList or Major metrics of Alibaba Cloud services. | None |
GroupId | String | Yes | Yes | The ID of the application group. | None |
MetricName | String | Yes | Yes | The name of the metric. For more information, see DescribeMetricMetaList or Major metrics of Alibaba Cloud services. | None |
Escalations | Map | Yes | Yes | The alert settings. | For more information, see the Escalations properties section. |
EmailSubject | String | No | Yes | The subject of the alert notification email. | None |
Webhook | String | No | Yes | The webhook address to which a request is sent when an alert is triggered. | None |
RuleName | String | Yes | Yes | The name of the alert rule. | None |
Interval | Integer | No | Yes | The interval at which Cloud Monitor checks whether the alert rule is triggered. The default value is the lowest frequency at which the metric is polled. |
Unit: seconds. We recommend that you set this interval to the data aggregation period. If this interval is shorter than the data aggregation period, alerts cannot be triggered due to insufficient data. |
