Creating a Custom Alarm Template

Function

This API is used to create a custom alarm template.

Debugging

You can debug this API through automatic authentication in API Explorer or use the SDK sample code generated by API Explorer.

Authorization Information

Each account has all the permissions required to call all APIs, but IAM users must be assigned the required permissions.

If you are using role/policy-based authorization, see Permissions Policies and Supported Actions for details on the required permissions.

If you are using identity policy-based authorization, the following identity policy-based permissions are required.

Action	Access Level	Resource Type (*: required)	Condition Key	Alias	Dependencies

is_overwrite	No	Boolean	Definition Whether to overwrite the existing alarm template with the same name. Constraints N/A Range A boolean value. true: Overwrite the alarm template with the same name. false: Create an alarm template instead of overwriting the alarm template with the same name.

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	Yes	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
extra_info	No	MetricExtraInfo object	Definition Additional information about the alarm policy. Constraints N/A
period	Yes	Integer	Definition Interval (seconds) for checking whether the alarm rule conditions are met. Constraints N/A Range The value can be: 0: default value. This value can be used for event alarms. 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.

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. Default Value N/A
value	No	Number	Definition Alarm threshold. 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 N/A Default Value N/A
hierarchical_value	No	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.
