Response Parameters

Status code: 200

**Table 3** Response body parameters
Parameter	Type	Description
alarm_histories	Array of AlarmHistoryItem objects	Alarm records.
count	Integer	Total number of alarm records.

**Table 4** AlarmHistoryItem
Parameter	Type	Description
record_id	String	Alarm record.
alarm_id	String	Alarm rule ID.
name	String	Alarm rule name.
status	String	Status of the alarm record. The value can be ok, alarm, or invalid.
type	String	Alarm rule type. ALL_INSTANCE indicates alarm rules for metrics of all resources. RESOURCE_GROUP indicates alarm rules for metrics of resources in a resource group. MULTI_INSTANCE indicates alarm rules for metrics of specified resources. EVENT.SYS indicates alarm rules for system events. EVENT.CUSTOM indicates alarm rules for custom events. DNSHealthCheck indicates alarm rules for health checks.
level	Integer	Severity of the alarm record. The value can be 1 (critical), 2 (major), 3 (minor), or 4 (warning).
begin_time	String	Generation time (UTC).
metric	AlarmMetric object	Alarm metric information.
condition	AlarmCondition object	Alarm triggering condition.
additional_info	AdditionalInfo object	Additional field of an alarm record, which applies only to alarm records generated in event monitoring scenarios.
data_points	Array of DataPointInfo objects	Time when the resource monitoring data is reported and the monitoring data in the alarm record.

**Table 5** AlarmMetric
Parameter	Type	Description
namespace	String	Namespace of the service to be queried.
metric_name	String	Metric name of the resource.
dimensions	Array of AlarmMetricDimension objects	Metric dimension. A maximum of four dimensions can be added.

**Table 6** AlarmMetricDimension
Parameter	Type	Description
name	String	Resource dimension.
value	String	Resource dimension value.

**Table 7** AlarmCondition
Parameter	Type	Description
period	Integer	Monitoring period of a metric, in second. The default value is 0. For an event alarm, set this parameter to 0. 1 indicates the original period of a metric. For example, if the original period of an RDS metric is 60 seconds, the interval between its data points is 60 seconds.
filter	String	Rollup method. The value can be average, min, max, or sum.
comparison_operator	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; cycle_wave indicates the increase or decrease compared with the last period.
value	Double	Alarm threshold.
unit	String	Data unit, which cannot exceed 32 characters.
count	Integer	Times.
suppress_duration	Integer	Alarm suppression time, in second. 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.

**Table 8** AdditionalInfo
Parameter	Type	Description
resource_id	String	ID of the resource corresponding to the alarm record.
resource_name	String	Name of the resource corresponding to the alarm record.
event_id	String	Event monitoring ID corresponding to the alarm record, which is the event generated by the resource.

**Table 9** DataPointInfo
Parameter	Type	Description
time	String	UTC time when the resource monitoring data of the alarm record is reported.
value	Double	Resource monitoring data of the alarm record at the time point.

Status code: 400

**Table 10** Response body parameters

error_code	String	Error code.
error_msg	String	Error message.

Status code: 401

**Table 11** Response body parameters
Parameter	Type	Description
error_code	String	Error code.
error_msg	String	Error message.

Status code: 500
