**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Definition Project ID. It is used to specify the project that an asset belongs to. You can query the assets of a project by project ID. You can obtain the project ID from the API or console. For details, see Obtaining a Project ID. Constraints N/A Range 1 to 64 characters. Default Value N/A
template_id	Yes	String	Definition ID of the custom alarm template to update. Example: at1603330892378wkDm77y6B Constraints N/A Range The value starts with at and allows a maximum of 64 characters. It can contain letters and digits. Default Value N/A

Request Parameters

**Table 2** Request header parameters
Parameter	Mandatory	Type	Description
Content-Type	No	String	Definition MIME type of the request body. Constraints N/A Range 1 to 64 characters Default Value Default value application/json; charset=UTF-8 is recommended. For APIs used to upload objects or images, the MIME type varies with the flow type.
X-Auth-Token	No	String	Definition User token. Constraints N/A Range 1 to 16,384 characters Default Value N/A

**Table 3** Request body parameters
Parameter	Mandatory	Type	Description
template_name	Yes	String	Definition Name of a custom alarm template. Constraints N/A Range The value allows 1 to 128 characters and can only contain letters, digits, underscores (_), and hyphens (-). Default Value N/A
template_description	No	String	Definition Details about the custom alarm template. Constraints N/A Range 0 to 256 characters. Default Value N/A
namespace	Yes	String	Definition Service namespace, which is the resource type selected when you create a custom alarm template. For example, the ECS namespace is SYS.ECS . For details about the namespace of each service, see Services Interconnected with Cloud Eye. Constraints N/A Range The value is in the service.item format. The values of service and item must start with a letter and contain only letters, digits, and underscores (_). It can contain 3 to 32 characters. Default Value N/A
dimension_name	Yes	String	Definition Metric dimension corresponding to the resource type. If the ECS resource type is selected, the value of dimension_name is instance_id . For details about the dimension names of each resource, see their service documentation. You can navigate there from Services Interconnected with Cloud Eye. Constraints N/A Range The value must start with a letter. Each dimension allows a maximum of 32 characters and can only contain digits, letters, underscores (_), and hyphens (-). Multiple dimensions are separated by commas (,). A maximum of four dimensions are supported. A maximum of 131 characters are allowed. Example: instance_id for single-dimension scenarios and instance_id,disk for multi-dimension scenarios. Default Value N/A
template_items	Yes	Array of TemplateItem objects	Alarm rules that you add to the custom alarm template. You can add up to 30 alarm rules.

**Table 4** TemplateItem
Parameter	Mandatory	Type	Description
metric_name	Yes	String	Definition Metric added to the alarm template. For example, you can add an ECS metric cpu_util . For details about the metric names of each service, see their documentation. You can navigate there from Services Interconnected with Cloud Eye. Constraints N/A Range 1 to 64 characters. Default Value N/A
condition	Yes	AlarmTemplateCondition object	Alarm policy you created for the custom alarm template.
alarm_level	No	Integer	Definition Alarm severity. Constraints N/A Range The value can be: 1: critical. 2: major. 3: minor. 4: warning. Default Value N/A

**Table 5** AlarmTemplateCondition
Parameter	Mandatory	Type	Description
comparison_operator	Yes	String	Definition Threshold symbol. Constraints The threshold symbols for metric alarms are >, >=, <, <=, =, !=, cycle_decrease, cycle_increase, and cycle_wave. The threshold symbols for event alarms are >, >=, <, <=, =, and !=. Range The value can be >, <, >=, <=, =, !=, cycle_decrease, cycle_increase, or cycle_wave. cycle_decrease indicates the decrease relative to the last period. cycle_increase indicates the increase relative to the last period. cycle_wave indicates the increase or decrease relative to the last period.
count	Yes	Integer	Definition Number of consecutive times that an alarm is triggered. Constraints N/A Range An integer ranging from 1 to 5. Default Value N/A
filter	Yes	String	Definition Data aggregation method. Constraints When period is set to 1 (original value), the filter field does not take effect. The default value of filter is average. The filter parameter takes effect only when period is greater than 1. Range The value can be: average variance min: minimum value. max: maximum value. sum Default Value N/A
period	Yes	Integer	Definition Metric period, in seconds. For details about the original metric period for each cloud service, see Services Interconnected with Cloud Eye. ConstraintsThe value can be: 0: The alarm is triggered immediately. This value applies only to event scenarios. 1: original metric period. For example, if the original period of an RDS metric is 60s, the metric data is collected and calculated every 60s. 300: The metric data is collected and calculated every 5 minutes. 1200: The metric data is collected and calculated every 20 minutes. 3600: The metric data is collected and calculated every hour. 14400: The metric data is collected and calculated every 4 hours. 86400: The metric data is collected and calculated every day. Default Value N/A Range N/A
unit	No	String	Definition Data unit. Constraints N/A Range 0 to 32 characters Default Value N/A
value	Yes	Number	Definition Alarm threshold. For detailed thresholds, see the value range of each metric in the appendix. For example, you can set ECS cpu_util in Services Interconnected with Cloud Eye to 80 . Constraints If there is only one threshold, value and alarm_level are used in pairs. If there are both hierarchical_value and value , hierarchical_value is used. Range -1.7976931348623157e+108 to 1.7976931348623157e+108 Default Value N/A
suppress_duration	No	Integer	Definition Alarm suppression duration, in seconds. This parameter corresponds to the last field in the alarm policy when you create an alarm rule. This field is used to mitigate frequent alarm occurrences. Constraints N/A Range The value can be: 0: A metric alarm is generated only once. An event alarm is not suppressed in the immediate triggering scenario, and is generated only once in the accumulated triggering scenario. 300: An alarm is generated every 5 minutes once the alarm triggering condition is met. 600: An alarm is generated every 10 minutes once the alarm triggering condition is met. 900: An alarm is generated every 15 minutes once the alarm triggering condition is met. 1800: An alarm is generated every 30 minutes once the alarm triggering condition is met. 3600: An alarm is generated every 60 minutes once the alarm triggering condition is met. 10800: An alarm is generated every 3 hours once the alarm triggering condition is met. 21600: An alarm is generated every 6 hours once the alarm triggering condition is met. 43200: An alarm is generated every 12 hours once the alarm triggering condition is met. 86400: An alarm is generated once every day once the alarm triggering condition is met. Default Value N/A
