18				Paws::EMR::CloudWatchAlarmDefinition
19
20				=head1 USAGE
21
22				This class represents one of two things:
23
24				=head3 Arguments in a call to a service
25
26				Use the attributes of this class as arguments to methods. You shouldn't make instances of this class.
27				Each attribute should be used as a named argument in the calls that expect this type of object.
28
29				As an example, if Att1 is expected to be a Paws::EMR::CloudWatchAlarmDefinition object:
30
31				$service_obj->Method(Att1 => { ComparisonOperator => $value, ..., Unit => $value });
32
33				=head3 Results returned from an API call
34
35				Use accessors for each attribute. If Att1 is expected to be an Paws::EMR::CloudWatchAlarmDefinition object:
36
37				$result = $service_obj->Method(...);
38				$result->Att1->ComparisonOperator
39
40				=head1 DESCRIPTION
41
42				The definition of a CloudWatch metric alarm, which determines when an
43				automatic scaling activity is triggered. When the defined alarm
44				conditions are satisfied, scaling activity begins.
45
46				=head1 ATTRIBUTES
47
48
49				=head2 B<REQUIRED> ComparisonOperator => Str
50
51				Determines how the metric specified by C<MetricName> is compared to the
52				value specified by C<Threshold>.
53
54
55				=head2 Dimensions => ArrayRef[L<Paws::EMR::MetricDimension>]
56
57				A CloudWatch metric dimension.
58
59
60				=head2 EvaluationPeriods => Int
61
62				The number of periods, expressed in seconds using C<Period>, during
63				which the alarm condition must exist before the alarm triggers
64				automatic scaling activity. The default value is C<1>.
65
66
67				=head2 B<REQUIRED> MetricName => Str
68
69				The name of the CloudWatch metric that is watched to determine an alarm
70				condition.
71
72
73				=head2 Namespace => Str
74
75				The namespace for the CloudWatch metric. The default is
76				C<AWS/ElasticMapReduce>.
77
78
79				=head2 B<REQUIRED> Period => Int
80
81				The period, in seconds, over which the statistic is applied. EMR
82				CloudWatch metrics are emitted every five minutes (300 seconds), so if
83				an EMR CloudWatch metric is specified, specify C<300>.
84
85
86				=head2 Statistic => Str
87
88				The statistic to apply to the metric associated with the alarm. The
89				default is C<AVERAGE>.
90
91
92				=head2 B<REQUIRED> Threshold => Num
93
94				The value against which the specified statistic is compared.
95
96
97				=head2 Unit => Str
98
99				The unit of measure associated with the CloudWatch metric being
100				watched. The value specified for C<Unit> must correspond to the units
101				specified in the CloudWatch metric.
