Overview

Note:

When passing DescribeAlarmsInput as input to an Aws::Client method, you can use a vanilla Hash:

{
  alarm_names: ["AlarmName"],
  alarm_name_prefix: "AlarmNamePrefix",
  alarm_types: ["CompositeAlarm"], # accepts CompositeAlarm, MetricAlarm
  children_of_alarm_name: "AlarmName",
  parents_of_alarm_name: "AlarmName",
  state_value: "OK", # accepts OK, ALARM, INSUFFICIENT_DATA
  action_prefix: "ActionPrefix",
  max_records: 1,
  next_token: "NextToken",
}

Instance Attribute Details

#action_prefixString

Use this parameter to filter the results of the operation to only those alarms that use a certain alarm action. For example, you could specify the ARN of an SNS topic to find all alarms that send notifications to that topic.

Returns:

  • (String)

    Use this parameter to filter the results of the operation to only those alarms that use a certain alarm action.

#alarm_name_prefixString

An alarm name prefix. If you specify this parameter, you receive information about all alarms that have names that start with this prefix.

If this parameter is specified, you cannot specify AlarmNames.

Returns:

  • (String)

    An alarm name prefix.

#alarm_namesArray<String>

The names of the alarms to retrieve information about.

Returns:

  • (Array<String>)

    The names of the alarms to retrieve information about.

#alarm_typesArray<String>

Use this parameter to specify whether you want the operation to return metric alarms or composite alarms. If you omit this parameter, only metric alarms are returned.

Returns:

  • (Array<String>)

    Use this parameter to specify whether you want the operation to return metric alarms or composite alarms.

#children_of_alarm_nameString

If you use this parameter and specify the name of a composite alarm, the operation returns information about the \"children\" alarms of the alarm you specify. These are the metric alarms and composite alarms referenced in the AlarmRule field of the composite alarm that you specify in ChildrenOfAlarmName. Information about the composite alarm that you name in ChildrenOfAlarmName is not returned.

If you specify ChildrenOfAlarmName, you cannot specify any other parameters in the request except for MaxRecords and NextToken. If you do so, you receive a validation error.

Only the Alarm Name, ARN, StateValue (OK/ALARM/INSUFFICIENT_DATA), and StateUpdatedTimestamp information are returned by this operation when you use this parameter. To get complete information about these alarms, perform another DescribeAlarms operation and specify the parent alarm names in the AlarmNames parameter.

Returns:

  • (String)

    If you use this parameter and specify the name of a composite alarm, the operation returns information about the \"children\" alarms of the alarm you specify.

#max_recordsInteger

The maximum number of alarm descriptions to retrieve.

Returns:

  • (Integer)

    The maximum number of alarm descriptions to retrieve.

#next_tokenString

The token returned by a previous call to indicate that there is more data available.

Returns:

  • (String)

    The token returned by a previous call to indicate that there is more data available.

#parents_of_alarm_nameString

If you use this parameter and specify the name of a metric or composite alarm, the operation returns information about the \"parent\" alarms of the alarm you specify. These are the composite alarms that have AlarmRule parameters that reference the alarm named in ParentsOfAlarmName. Information about the alarm that you specify in ParentsOfAlarmName is not returned.

If you specify ParentsOfAlarmName, you cannot specify any other parameters in the request except for MaxRecords and NextToken. If you do so, you receive a validation error.

Only the Alarm Name and ARN are returned by this operation when you use this parameter. To get complete information about these alarms, perform another DescribeAlarms operation and specify the parent alarm names in the AlarmNames parameter.

Returns:

  • (String)

    If you use this parameter and specify the name of a metric or composite alarm, the operation returns information about the \"parent\" alarms of the alarm you specify.

#state_valueString

Specify this parameter to receive information only about alarms that are currently in the state that you specify.

Possible values:

  • OK
  • ALARM
  • INSUFFICIENT_DATA

Returns:

  • (String)

    Specify this parameter to receive information only about alarms that are currently in the state that you specify.
