DESCRIPTION

This class represents the parameters used for calling the method DescribeAlarms on the Amazon CloudWatch service. Use the attributes of this class as arguments to method DescribeAlarms.

You shouldn't make instances of this class. Each attribute should be used as a named argument in the call to DescribeAlarms.

SYNOPSIS

    my $monitoring = Paws->service('CloudWatch');
    my $DescribeAlarmsOutput = $monitoring->DescribeAlarms(
      ActionPrefix    => 'MyActionPrefix',       # OPTIONAL
      AlarmNamePrefix => 'MyAlarmNamePrefix',    # OPTIONAL
      AlarmNames      => [
        'MyAlarmName', ...                       # min: 1, max: 255
      ],    # OPTIONAL
      AlarmTypes => [
        'CompositeAlarm', ...    # values: CompositeAlarm, MetricAlarm
      ],    # OPTIONAL
      ChildrenOfAlarmName => 'MyAlarmName',    # OPTIONAL
      MaxRecords          => 1,                # OPTIONAL
      NextToken           => 'MyNextToken',    # OPTIONAL
      ParentsOfAlarmName  => 'MyAlarmName',    # OPTIONAL
      StateValue          => 'OK',             # OPTIONAL
    );
    # Results:
    my $CompositeAlarms = $DescribeAlarmsOutput->CompositeAlarms;
    my $MetricAlarms    = $DescribeAlarmsOutput->MetricAlarms;
    my $NextToken       = $DescribeAlarmsOutput->NextToken;
    # Returns a L<Paws::CloudWatch::DescribeAlarmsOutput> object.

Values for attributes that are native types (Int, String, Float, etc) can passed as-is (scalar values). Values for complex Types (objects) can be passed as a HashRef. The keys and values of the hashref will be used to instance the underlying object. For the AWS API documentation, see <https://docs.aws.amazon.com/goto/WebAPI/monitoring/DescribeAlarms>

ATTRIBUTES

ActionPrefix => Str

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.

AlarmNamePrefix => Str

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".

AlarmNames => ArrayRef[Str|Undef]

The names of the alarms to retrieve information about.

AlarmTypes => ArrayRef[Str|Undef]

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.

ChildrenOfAlarmName => Str

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.

MaxRecords => Int

The maximum number of alarm descriptions to retrieve.

NextToken => Str

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

ParentsOfAlarmName => Str

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.

StateValue => Str

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

Valid values are: "OK", "ALARM", "INSUFFICIENT_DATA"
