URI

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

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Specifies the tenant ID. Minimum: 1 Maximum: 64
alarm_id	Yes	String	Specifies the alarm rule ID. Regex Pattern: ^al([0-9A-Za-z]){22}$

Request Parameters

**Table 2** Request header parameters
Parameter	Mandatory	Type	Description
Content-Type	No	String	Specifies the MIME type of the request body. The default type is application/json; charset=UTF-8. Default: application/json; charset=UTF-8 Minimum: 1 Maximum: 64
X-Auth-Token	No	String	Specifies the user token. Minimum: 1 Maximum: 16384

**Table 3** Request body parameters
Parameter	Mandatory	Type	Description
policies	Yes	Array of UpdatePolicy objects	Specifies the policy information. Array Length: 1 - 50

**Table 4** UpdatePolicy
Parameter	Mandatory	Type	Description
metric_name	Yes	String	Specifies the 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.
period	Yes	Integer	Specifies the rollup 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. Minimum: 0 Maximum: 86400 Enumeration values: 0 1 300 1200 3600 14400 86400
filter	Yes	String	Specifies the rollup method. The value can be average, min, max, or sum.
comparison_operator	Yes	String	Specifies the 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	Yes	Number	Specifies the threshold.
unit	No	String	Specifies the metric unit.
type	No	String	Specifies the alarm policy type. This parameter is left blank by default. Minimum: 0 Maximum: 32
count	Yes	Integer	Specifies the number of times that the alarm triggering conditions are met. 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	Specifies the 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. Minimum: 0 Maximum: 86400 Enumeration values: 0 300 600 900 1800 3600 10800 21600 43200 86400
level	No	Integer	Specifies the alarm severity, which can be 1 (critical), 2 (major), 3 (minor), or 4 (informational).
