Create Alert Rule¶

Create an alert rule.

Prerequisites¶

Ensure that the specified model (modelId) is available under the organization.
Ensure that the specified measuring point (measurepointId) is valid.
Ensure that the specified alert severity (severityId) exists.
Ensure that the specified alert content (contentId) exists.
Ensure that the specified scope (scope) of asset nodes where the rule takes effect exists.

Request Format¶

POST https://{apigw-address}/event-service/v2.1/alert-rules?action=create

Request Parameters (URI)¶

Name	Location (Path/Query)	Mandatory/Optional	Data Type	Description
orgId	Query	Mandatory	String	The organization ID which the asset belongs to. How to get orgId>>

Request Parameters (Body)¶

Note

You must specify either measurepointId or deviceStatus as the trigger of the alert.

Name	Mandatory/Optional	Data Type	Description
ruleId	Mandatory	String	The alert rule ID.
ruleDesc	Mandatory	StringI18n	Specify the alert rule’s description in its respective locale’s language. For more details on the structure and locales supported, see Internationalized name struct.
modelId	Mandatory	String	The model ID. How to get modelID>>
measurepointId	Optional	String	The measurement point ID. You must specify either `measurepointId` or `deviceStatus` as the trigger of the alert. How to get pointId>>
deviceStatus	Optional	String	The device status, such as “offline”. You must specify either `measurepointId` or `deviceStatus` as the trigger of the alert. For more details, see Setting State-based Alerts.
condition	Mandatory	String	The query expression. For example, “${temperature} = 19” indicates that the value of the measurement point “temperature” is 19. A slash “/” is used to express the hierarchical relationship, for which only one downward layer is supported for now. For example, “${pointA/att1} = 18” indicates the “att1” attribute value of the measurement point “A” is 18. How to use expression>>
severityId	Mandatory	String	The alert severity ID.
contentId	Mandatory	String	The alert content ID.
tags	Optional	Map	The user-defined tags. (The Key and Value are of String type.) For details, see How to use tags.
isEnabled	Optional	Boolean	true (default) = enables the alert rule false = does not enable the alert rule
isRoot	Optional	Boolean	true = a root alert false (default) = not a root alert
scope	Mandatory	Array of AssetNode Structs	Uses the AssetNode struct to indicate the scope of the asset to which the alert applies to. For details, see AssetNode Struct.
triggeringDelayTimer	Optional	Integer	The amount of time to delay triggering the alert. The unit is seconds with a range between [60 - 10800]. The alert will only be triggered when an anomaly that matches the alert rule occurs and does not return to normal within the set time. To trigger the alert immediately, set the time to 0. For more information, see Tutorial: Setting Alert Triggering Delay Timer.

AssetNode Struct ¶

Name	Mandatory/Optional	Data Type	Description
treeId	Mandatory	String	The asset tree ID. Alternatively, you can set it as “all” to include all the asset trees in the specified `orgID`.
assetId	Mandatory	String	The asset ID. How to get assetId>>

Response Parameters¶

Name	Data Type	Description
data	String	The rule ID.
