**Table 3** Response body parameters
Parameter	Type	Description
template_id	String	ID of an alarm template. The ID starts with at and is followed by up to 64 characters, including letters and digits.
template_name	String	Definition Alarm template name. Constraints N/A Range The value allows 1 to 128 characters. It must start with a letter and can only contain letters, digits, underscores (_), and hyphens (-). Default Value N/A
template_type	String	Type of an alarm template. custom indicates custom alarm templates, and system indicates default alarm templates.
create_time	String	Time when an alarm template was created.
template_description	String	Definition Alarm template description. Constraints N/A Range [0,256] Default Value An empty string
policies	Array of AlarmTemplatePolicies objects	Alarm policies in an alarm template.

**Table 4** AlarmTemplatePolicies
Parameter	Type	Description
namespace	String	Definition Namespace of a service. For details about the namespace of each service, see Service Namespaces. Constraints N/A Range The value is in the service.item format. The values of service and item must be a string, starting with a letter and containing only digits (0–9), letters (case-insensitive), and underscores (_). The value must contain 3 to 32 characters. Default Value N/A
dimension_name	String	Definition Resource dimension. Constraints The DimensionName field of the event alarm template is empty. 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. Example: instance_id for single-dimension scenarios and instance_id,disk for multi-dimension scenarios. Default Value N/A
metric_name	String	Definition Metric name of a resource. For details about the metrics of each service, see Service Metric Names. Constraints N/A Range The value must start with a letter and can only contain digits, letters, underscores (_), and hyphens (-). 1 to 96 characters For example, the ECS metric cpu_util indicates the CPU usage of an ECS. The DDS metric mongo001_command_ps indicates the command execution frequency. Default Value N/A
period	Integer	Interval (seconds) for checking whether the alarm rule conditions are met.
filter	String	Data rollup method.
comparison_operator	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. Default Value N/A
value	Number	Alarm threshold. If there is only one threshold, value and alarm_level are used in pairs. If there are both hierarchical_value and value, hierarchical_value prevails.
hierarchical_value	HierarchicalValue object	Definition Multi-level alarm threshold. Constraints If there are both hierarchical_value and value, hierarchical_value is used. When you create or modify an alarm rule, you can set only one threshold in the following scenarios: The alarm type is Metric and the alarm policy is Trigger an alarm when all policies are met. The alarm type is Event.
unit	String	Data unit. The value can contain up to 32 characters.
count	Integer	Definition Number of times that the alarm triggering conditions are met. Constraints N/A Range For event alarms, the value ranges from 1 to 180. For metric and website alarms, the value can be 1, 2, 3, 4, 5, 10, 15, 30, 60, 90, 120, or 180. Default Value N/A
alarm_level	Integer	Definition Alarm severity. Constraints N/A Range The value can be: 1: critical 2: major 3: minor 4: warning Default Value N/A
suppress_duration	Integer	Alarm suppression period, in seconds. When the period is 0, only one alarm is generated.
selected_unit	String	Definition The metric unit you selected. It is used for subsequent metric data display and calculation. Constraints N/A Range [0,64] Default Value N/A

**Table 5** HierarchicalValue
Parameter	Type	Description
critical	Double	Definition Threshold for critical alarms. Constraints N/A Range [-1.7976931348623157e+108, 1.7976931348623157e+108] Default Value N/A
major	Double	Definition Threshold for major alarms. Constraints N/A Range [-1.7976931348623157e+108, 1.7976931348623157e+108] Default Value N/A
minor	Double	Definition Threshold for minor alarms. Constraints N/A Range [-1.7976931348623157e+108, 1.7976931348623157e+108] Default Value N/A
info	Double	Definition Threshold for warnings. Constraints N/A Range [-1.7976931348623157e+108, 1.7976931348623157e+108] Default Value N/A
