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

URI

PUT /v2/{project_id}/alarms/{alarm_id}/policies

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Definition Tenant ID. Constraints: None Value range: Project ID, 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 by calling an API or on the console. For details, see Obtaining a Project ID. The value must contain of 1 to 64 characters. Default value: None
alarm_id	Yes	String	Alarm rule ID. Regex Pattern: ^al([0-9A-Za-z]){22}$

Request Parameters

**Table 2** Request header parameters
Parameter	Mandatory	Type	Description
Content-Type	Yes	String	Definition MIME type of the request body. Constraints: None Value range: The value can contain 1 to 64 characters. Default value: The default type is application/json; charset=UTF-8. Default value: application/json; charset=UTF-8
X-Auth-Token	Yes	String	Definition User token. Constraints: None Value range: The value can contain 1 to 16,384 characters. Default value: None

**Table 3** Request body parameters
Parameter	Mandatory	Type	Description
policies	Yes	Array of UpdatePolicyReq objects	Policy information.

**Table 4** UpdatePolicyReq
Parameter	Mandatory	Type	Description
metric_name	Yes	String	Metric name of a resource. The name must start with a letter and contain only digits, letters, and underscores. The length ranges from 1 to 64 characters. For example, cpu_util of an ECS indicates the CPU usage of the ECS. mongo001_command_ps in DDS indicates the command execution frequency. For details about the metric name of each service, see Service metric name.
extra_info	No	MetricExtraInfo object	If the policy does not contain additional information, extra_info does not need to be transferred.
period	Yes	Integer	Monitoring period of a metric, in seconds. The default value is 0. For an event alarm, set this parameter to 0. 1 indicates the original rollup period of a metric. For example, if the original rollup period of an RDS metric is 60s, its data point is calculated every 60 seconds. For details about the original rollup period of each cloud service metric, see Services Interconnected with Cloud Eye. 300 indicates that the metric rollup period is 5 minutes. Value range: 0-86400 Enumeration values: 0 1 300 1200 3600 14400 86400
filter	Yes	String	Aggregation mode. average: average value; variance: variance; min: minimum value; max: maximum value; sum: sum; tp99: 99 percentile; tp95: 95 percentile; tp90: 90 percentile
comparison_operator	Yes	String	Threshold symbol. The value can be >, <, >=, <=, =, !=, cycle_decrease, cycle_increase, or cycle_wave. cycle_decrease indicates the decrease compared with the last period, cycle_increase indicates the increase compared with the last period, and cycle_wave indicates the increase or decrease compared with the last period. All of them can be used in alarm rules for metrics. >, <, >=, <=, =, and != can be used for alarm rules for events.
value	No	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 is used. For detailed thresholds, see the value range of each metric in the appendix. For example, you can set ECS cpu_util to 80. For detailed thresholds, see the value range of each metric in the appendix. For example, you can set ECS cpu_util to 80 in Services Interconnected with Cloud Eye.
hierarchical_value	No	HierarchicalValue object	Multi-level alarm threshold. If there are both hierarchical_value and value, hierarchical_value prevails. 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	No	String	Data unit.
type	No	String	Alarm policy type. This API has been deprecated. Regex Pattern: ^(auto)$
count	Yes	Integer	Number of consecutive alarm triggering times. 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.
suppress_duration	No	Integer	Alarm suppression time, in seconds. This parameter corresponds to the last field in the alarm policy when an alarm rule is created on the Cloud Eye console. This field is used to avoid frequent alarms. 0 indicates that the alarm is not suppressed and alarms are generated as long as the conditions are met. 300 indicates that an alarm is generated every 5 minutes as long as the alarm triggering conditions are met. Value range: 0-86400 Enumeration values: 0 300 600 900 1800 3600 10800 21600 43200 86400
level	No	Integer	Alarm severity, which can be 1 (critical), 2 (major), 3 (minor), or 4 (informational). The default value is 2.
namespace	No	String	The namespace and dimension_name parameters are added to the product-level rule to specify the policy to which the product belongs. For details about the namespace of each service, see [Service Namespace] (ces_03_0059.xml). Regex Pattern: ^((([a-z]\|[A-Z]){1}([a-z]\|[A-Z]\|[0-9]\|_)\.([a-z]\|[A-Z]){1}([a-z]\|[A-Z]\|[0-9]\|_))\|)$
dimension_name	No	String	The namespace and dimension_name parameters are added to the product-level rule to specify the policy to which the product belongs. Currently, a maximum of four dimensions are supported. For details about the metric dimension name of each service resource, see [Service dimension name] (ces_03_0059.xml). Example: instance_id in the single-dimension scenario; instance_id,disk in the multi-dimension scenario Regex Pattern: ^(([a-z]\|[A-Z]){1}([a-z]\|[A-Z]\|[0-9]\|_\|-\|\.){0,31}(,([a-z]\|[A-Z]){1}([a-z]\|[A-Z]\|[0-9]\|_\|-\|\.){0,31}){0,3}\|)$

Parameter	Mandatory	Type	Description
origin_metric_name	Yes	String	Original metric name. Regex Pattern: ^([a-z]\|[A-Z]\|[0-9]\|_\|-\|~\|\.\|/\|:)*$
metric_prefix	No	String	Metric name prefix. Regex Pattern: ^([a-z]\|[A-Z]\|[0-9]\|_\|-\|~\|\.\|/\|:)*$
custom_proc_name	No	String	Name of a user process.
