=head1 NAME

Paws::CloudWatch - Perl Interface to AWS Amazon CloudWatch

=head1 SYNOPSIS

  use Paws;

  my $obj = Paws->service('CloudWatch');
  my $res = $obj->Method(
    Arg1 => $val1,
    Arg2 => [ 'V1', 'V2' ],
    # if Arg3 is an object, the HashRef will be used as arguments to the constructor
    # of the arguments type
    Arg3 => { Att1 => 'Val1' },
    # if Arg4 is an array of objects, the HashRefs will be passed as arguments to
    # the constructor of the arguments type
    Arg4 => [ { Att1 => 'Val1'  }, { Att1 => 'Val2' } ],
  );

=head1 DESCRIPTION

Amazon CloudWatch monitors your Amazon Web Services (AWS) resources and
the applications you run on AWS in real time. You can use CloudWatch to
collect and track metrics, which are the variables you want to measure
for your resources and applications.

CloudWatch alarms send notifications or automatically change the
resources you are monitoring based on rules that you define. For
example, you can monitor the CPU usage and disk reads and writes of
your Amazon EC2 instances. Then, use this data to determine whether you
should launch additional instances to handle increased load. You can
also use this data to stop under-used instances to save money.

In addition to monitoring the built-in metrics that come with AWS, you
can monitor your own custom metrics. With CloudWatch, you gain
system-wide visibility into resource utilization, application
performance, and operational health.

For the AWS API documentation, see L<https://docs.aws.amazon.com/cloudwatch/>


=head1 METHODS

=head2 DeleteAlarms

=over

=item AlarmNames => ArrayRef[Str|Undef]


=back

Each argument is described in detail in: L<Paws::CloudWatch::DeleteAlarms>

Returns: nothing

Deletes the specified alarms. You can delete up to 100 alarms in one
operation. However, this total can include no more than one composite
alarm. For example, you could delete 99 metric alarms and one composite
alarms with one operation, but you can't delete two composite alarms
with one operation.

In the event of an error, no alarms are deleted.

It is possible to create a loop or cycle of composite alarms, where
composite alarm A depends on composite alarm B, and composite alarm B
also depends on composite alarm A. In this scenario, you can't delete
any composite alarm that is part of the cycle because there is always
still a composite alarm that depends on that alarm that you want to
delete.

To get out of such a situation, you must break the cycle by changing
the rule of one of the composite alarms in the cycle to remove a
dependency that creates the cycle. The simplest change to make to break
a cycle is to change the C<AlarmRule> of one of the alarms to C<False>.

Additionally, the evaluation of composite alarms stops if CloudWatch
detects a cycle in the evaluation path.

Returns: a L<Paws::CloudWatch::GetInsightRuleReportOutput> instance

This operation returns the time series data collected by a Contributor
Insights rule. The data includes the identity and number of
contributors to the log group.

You can also optionally return one or more statistics about each data
point in the time series. These statistics can include the following:

=over

=item *

C<UniqueContributors> -- the number of unique contributors for each
data point.

=item *

C<MaxContributorValue> -- the value of the top contributor for each
data point. The identity of the contributor might change for each data
point in the graph.

If this rule aggregates by COUNT, the top contributor for each data
point is the contributor with the most occurrences in that period. If
the rule aggregates by SUM, the top contributor is the contributor with
the highest sum in the log field specified by the rule's C<Value>,
during that period.

different metrics in a single request, with a total of as many as
100,800 data points. You can also optionally perform math expressions
on the values of the returned statistics, to create new time series
that represent new insights into your data. For example, using Lambda
metrics, you could divide the Errors metric by the Invocations metric
to get an error rate time series. For more information about metric
math expressions, see Metric Math Syntax and Functions
(https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/using-metric-math.html#metric-math-syntax)
in the I<Amazon CloudWatch User Guide>.

Calls to the C<GetMetricData> API have a different pricing structure
than calls to C<GetMetricStatistics>. For more information about
pricing, see Amazon CloudWatch Pricing
(https://aws.amazon.com/cloudwatch/pricing/).

Amazon CloudWatch retains metric data as follows:

=over

=item *

Data points with a period of less than 60 seconds are available for 3
hours. These data points are high-resolution metrics and are available
only for custom metrics that have been defined with a
C<StorageResolution> of 1.

=item *

Data points with a period of 60 seconds (1-minute) are available for 15
days.

=item *

Data points with a period of 300 seconds (5-minute) are available for
63 days.

=item *

Data points with a period of 3600 seconds (1 hour) are available for
455 days (15 months).

=back

Data points that are initially published with a shorter period are
aggregated together for long-term storage. For example, if you collect
data using a period of 1 minute, the data remains available for 15 days
with 1-minute resolution. After 15 days, this data is still available,
but is aggregated and retrievable only with a resolution of 5 minutes.
After 63 days, the data is further aggregated and is available with a
resolution of 1 hour.

If you omit C<Unit> in your request, all data that was collected with
any unit is returned, along with the corresponding units that were
specified when the data was reported to CloudWatch. If you specify a
unit, the operation returns only data that was collected with that unit
specified. If you specify a unit that does not match the data
collected, the results of the operation are null. CloudWatch does not
perform unit conversions.

=back

Each argument is described in detail in: L<Paws::CloudWatch::GetMetricStatistics>

Returns: a L<Paws::CloudWatch::GetMetricStatisticsOutput> instance

Gets statistics for the specified metric.

The maximum number of data points returned from a single call is 1,440.
If you request more than 1,440 data points, CloudWatch returns an
error. To reduce the number of data points, you can narrow the
specified time range and make multiple requests across adjacent time
ranges, or you can increase the specified period. Data points are not
returned in chronological order.

CloudWatch aggregates data points based on the length of the period
that you specify. For example, if you request statistics with a
one-hour period, CloudWatch aggregates all data points with time stamps
that fall within each one-hour period. Therefore, the number of values
aggregated by CloudWatch is larger than the number of data points
returned.

CloudWatch needs raw data points to calculate percentile statistics. If
you publish data using a statistic set instead, you can only retrieve
percentile statistics for this data if one of the following conditions
is true:

=over

=item *

The SampleCount value of the statistic set is 1.

=item *

The Min and the Max values of the statistic set are equal.

=back

Percentile statistics are not available for metrics when any of the
metric values are negative numbers.

=back

Each argument is described in detail in: L<Paws::CloudWatch::PutCompositeAlarm>

Returns: nothing

Creates or updates a I<composite alarm>. When you create a composite
alarm, you specify a rule expression for the alarm that takes into
account the alarm states of other alarms that you have created. The
composite alarm goes into ALARM state only if all conditions of the
rule are met.

The alarms specified in a composite alarm's rule expression can include
metric alarms and other composite alarms.

Using composite alarms can reduce alarm noise. You can create multiple
metric alarms, and also create a composite alarm and set up alerts only
for the composite alarm. For example, you could create a composite
alarm that goes into ALARM state only when more than one of the
underlying metric alarms are in ALARM state.

Currently, the only alarm actions that can be taken by composite alarms
are notifying SNS topics.

It is possible to create a loop or cycle of composite alarms, where
composite alarm A depends on composite alarm B, and composite alarm B
also depends on composite alarm A. In this scenario, you can't delete
any composite alarm that is part of the cycle because there is always
still a composite alarm that depends on that alarm that you want to
delete.

To get out of such a situation, you must break the cycle by changing
the rule of one of the composite alarms in the cycle to remove a
dependency that creates the cycle. The simplest change to make to break
a cycle is to change the C<AlarmRule> of one of the alarms to C<False>.

Additionally, the evaluation of composite alarms stops if CloudWatch
detects a cycle in the evaluation path.

When this operation creates an alarm, the alarm state is immediately
set to C<INSUFFICIENT_DATA>. The alarm is then evaluated and its state
is set appropriately. Any actions associated with the new state are
then executed. For a composite alarm, this initial time after creation
is the only time that the alarm can be in C<INSUFFICIENT_DATA> state.

When you update an existing alarm, its state is left unchanged, but the
update completely overwrites the previous configuration of the alarm.

If you are an IAM user, you must have C<iam:CreateServiceLinkedRole> to
create a composite alarm that has Systems Manager OpsItem actions.


=head2 PutDashboard

=over

=item DashboardBody => Str

=item DashboardName => Str


=back

Each argument is described in detail in: L<Paws::CloudWatch::PutDashboard>

Returns: a L<Paws::CloudWatch::PutDashboardOutput> instance

Creates a dashboard if it does not already exist, or updates an
existing dashboard. If you update a dashboard, the entire contents are
replaced with what you specify here.

All dashboards in your account are global, not region-specific.

A simple way to create a dashboard using C<PutDashboard> is to copy an
existing dashboard. To copy an existing dashboard using the console,
you can load the dashboard and then use the View/edit source command in
the Actions menu to display the JSON block for that dashboard. Another
way to copy a dashboard is to use C<GetDashboard>, and then use the
data returned within C<DashboardBody> as the template for the new
dashboard when you call C<PutDashboard>.

When you create a dashboard with C<PutDashboard>, a good practice is to
add a text widget at the top of the dashboard with a message that the
dashboard was created by script and should not be changed in the
console. This message could also point console users to the location of
the C<DashboardBody> script or the CloudFormation template used to
create the dashboard.

Creates a Contributor Insights rule. Rules evaluate log events in a
CloudWatch Logs log group, enabling you to find contributor data for
the log events in that log group. For more information, see Using
Contributor Insights to Analyze High-Cardinality Data
(https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/ContributorInsights.html).

If you create a rule, delete it, and then re-create it with the same

Each argument is described in detail in: L<Paws::CloudWatch::PutMetricAlarm>

Returns: nothing

Creates or updates an alarm and associates it with the specified
metric, metric math expression, or anomaly detection model.

Alarms based on anomaly detection models cannot have Auto Scaling
actions.

When this operation creates an alarm, the alarm state is immediately
set to C<INSUFFICIENT_DATA>. The alarm is then evaluated and its state
is set appropriately. Any actions associated with the new state are
then executed.

When you update an existing alarm, its state is left unchanged, but the
update completely overwrites the previous configuration of the alarm.

If you are an IAM user, you must have Amazon EC2 permissions for some
alarm operations:

=over

=item *

The C<iam:CreateServiceLinkedRole> for all alarms with EC2 actions

=item *

The C<iam:CreateServiceLinkedRole> to create an alarm with Systems
Manager OpsItem actions.

=back

The first time you create an alarm in the AWS Management Console, the
CLI, or by using the PutMetricAlarm API, CloudWatch creates the
necessary service-linked role for you. The service-linked roles are
called C<AWSServiceRoleForCloudWatchEvents> and
C<AWSServiceRoleForCloudWatchAlarms_ActionSSM>. For more information,
see AWS service-linked role

=over

=item MetricData => ArrayRef[L<Paws::CloudWatch::MetricDatum>]

=item Namespace => Str


=back

Each argument is described in detail in: L<Paws::CloudWatch::PutMetricData>

Returns: nothing

Publishes metric data points to Amazon CloudWatch. CloudWatch
associates the data points with the specified metric. If the specified
metric does not exist, CloudWatch creates the metric. When CloudWatch
creates a metric, it can take up to fifteen minutes for the metric to
appear in calls to ListMetrics
(https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_ListMetrics.html).

You can publish either individual data points in the C<Value> field, or
arrays of values and the number of times each value occurred during the
period by using the C<Values> and C<Counts> fields in the
C<MetricDatum> structure. Using the C<Values> and C<Counts> method
enables you to publish up to 150 values per metric with one
C<PutMetricData> request, and supports retrieving percentile statistics
on this data.

Each C<PutMetricData> request is limited to 40 KB in size for HTTP POST
requests. You can send a payload compressed by gzip. Each request is
also limited to no more than 20 different metrics.

Although the C<Value> parameter accepts numbers of type C<Double>,
CloudWatch rejects values that are either too small or too large.
Values must be in the range of -2^360 to 2^360. In addition, special
values (for example, NaN, +Infinity, -Infinity) are not supported.

You can use up to 10 dimensions per metric to further clarify what data
the metric collects. Each dimension consists of a Name and Value pair.
For more information about specifying dimensions, see Publishing
Metrics
(https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/publishingMetrics.html)
in the I<Amazon CloudWatch User Guide>.

You specify the time stamp to be associated with each data point. You
can specify time stamps that are as much as two weeks before the
current date, and as much as 2 hours after the current day and time.

Data points with time stamps from 24 hours ago or longer can take at
least 48 hours to become available for GetMetricData
(https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_GetMetricData.html)
or GetMetricStatistics
(https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_GetMetricStatistics.html)
from the time they are submitted. Data points with time stamps between
3 and 24 hours ago can take as much as 2 hours to become available for
for GetMetricData
(https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_GetMetricData.html)
or GetMetricStatistics
(https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_GetMetricStatistics.html).

CloudWatch needs raw data points to calculate percentile statistics. If
you publish data using a statistic set instead, you can only retrieve
percentile statistics for this data if one of the following conditions
is true:

=over

=item *

The C<SampleCount> value of the statistic set is 1 and C<Min>, C<Max>,
and C<Sum> are all equal.

=item *

The C<Min> and C<Max> are equal, and C<Sum> is equal to C<Min>
multiplied by C<SampleCount>.

=back

Each argument is described in detail in: L<Paws::CloudWatch::PutMetricStream>

Returns: a L<Paws::CloudWatch::PutMetricStreamOutput> instance

Creates or updates a metric stream. Metric streams can automatically
stream CloudWatch metrics to AWS destinations including Amazon S3 and
to many third-party solutions.

For more information, see Using Metric Streams
(https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/Metric-Streams.html).

To create a metric stream, you must be logged on to an account that has
the C<iam:PassRole> permission and either the C<CloudWatchFullAccess>
policy or the C<cloudwatch:PutMetricStream> permission.

When you create or update a metric stream, you choose one of the
following:

=over

=item *

Stream metrics from all metric namespaces in the account.

=item *

Stream metrics from all metric namespaces in the account, except for
the namespaces that you list in C<ExcludeFilters>.

=item *

Stream metrics from only the metric namespaces that you list in
C<IncludeFilters>.

=back

When you use C<PutMetricStream> to create a new metric stream, the
stream is created in the C<running> state. If you use it to update an
existing stream, the state of the stream is not changed.

=over

=item AlarmName => Str

=item StateReason => Str

=item StateValue => Str

=item [StateReasonData => Str]


=back

Each argument is described in detail in: L<Paws::CloudWatch::SetAlarmState>

Returns: nothing

Temporarily sets the state of an alarm for testing purposes. When the
updated state differs from the previous value, the action configured
for the appropriate state is invoked. For example, if your alarm is
configured to send an Amazon SNS message when an alarm is triggered,
temporarily changing the alarm state to C<ALARM> sends an SNS message.

Metric alarms returns to their actual state quickly, often within
seconds. Because the metric alarm state change happens quickly, it is
typically only visible in the alarm's B<History> tab in the Amazon
CloudWatch console or through DescribeAlarmHistory
(https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_DescribeAlarmHistory.html).

If you use C<SetAlarmState> on a composite alarm, the composite alarm
is not guaranteed to return to its actual state. It returns to its
actual state only once any of its children alarms change state. It is
also reevaluated if you update its configuration.

If an alarm triggers EC2 Auto Scaling policies or application Auto
Scaling policies, you must include information in the
C<StateReasonData> parameter to enable the policy to take the correct
action.


=head2 StartMetricStreams

=over

=item Names => ArrayRef[Str|Undef]

Each argument is described in detail in: L<Paws::CloudWatch::TagResource>

Returns: a L<Paws::CloudWatch::TagResourceOutput> instance

Assigns one or more tags (key-value pairs) to the specified CloudWatch
resource. Currently, the only CloudWatch resources that can be tagged
are alarms and Contributor Insights rules.

Tags can help you organize and categorize your resources. You can also
use them to scope user permissions by granting a user permission to
access or change only resources with certain tag values.

Tags don't have any semantic meaning to AWS and are interpreted
strictly as strings of characters.

You can use the C<TagResource> action with an alarm that already has
tags. If you specify a new tag key for the alarm, this tag is appended
to the list of tags associated with the alarm. If you specify a tag key
that is already associated with the alarm, the new tag value that you
specify replaces the previous value for that tag.

You can associate as many as 50 tags with a CloudWatch resource.
