SDK for PHP 3.x

Client: Aws\ApplicationSignals\ApplicationSignalsClient
Service ID: application-signals
Version: 2024-04-15

This page describes the parameters and results for the operations of the Amazon CloudWatch Application Signals (2024-04-15), and shows how to use the Aws\ApplicationSignals\ApplicationSignalsClient object to call the described operations. This documentation is specific to the 2024-04-15 API version of the service.

Operation Summary

Each of the following operations can be created from a client using $client->getCommand('CommandName'), where "CommandName" is the name of one of the following operations. Note: a command is a value that encapsulates an operation and the parameters used to create an HTTP request.

You can also create and send a command immediately using the magic methods available on a client object: $client->commandName(/* parameters */). You can send the command asynchronously (returning a promise) by appending the word "Async" to the operation name: $client->commandNameAsync(/* parameters */).

Paginators

Paginators handle automatically iterating over paginated API results. Paginators are associated with specific API operations, and they accept the parameters that the corresponding API operation accepts. You can get a paginator from a client class using getPaginator($paginatorName, $operationParameters). This client supports the following paginators:

ListServiceDependencies
ListServiceDependents
ListServiceLevelObjectives
ListServiceOperations
ListServices

Operations

BatchGetServiceLevelObjectiveBudgetReport

$result = $client->batchGetServiceLevelObjectiveBudgetReport([/* ... */]);
$promise = $client->batchGetServiceLevelObjectiveBudgetReportAsync([/* ... */]);

Use this operation to retrieve one or more service level objective (SLO) budget reports.

An error budget is the amount of time in unhealthy periods that your service can accumulate during an interval before your overall SLO budget health is breached and the SLO is considered to be unmet. For example, an SLO with a threshold of 99.95% and a monthly interval translates to an error budget of 21.9 minutes of downtime in a 30-day month.

Budget reports include a health indicator, the attainment value, and remaining budget.

For more information about SLO error budgets, see SLO concepts.

CreateServiceLevelObjective

$result = $client->createServiceLevelObjective([/* ... */]);
$promise = $client->createServiceLevelObjectiveAsync([/* ... */]);

Creates a service level objective (SLO), which can help you ensure that your critical business operations are meeting customer expectations. Use SLOs to set and track specific target levels for the reliability and availability of your applications and services. SLOs use service level indicators (SLIs) to calculate whether the application is performing at the level that you want.

Create an SLO to set a target for a service or operation’s availability or latency. CloudWatch measures this target frequently you can find whether it has been breached.

When you create an SLO, you set an attainment goal for it. An attainment goal is the ratio of good periods that meet the threshold requirements to the total periods within the interval. For example, an attainment goal of 99.9% means that within your interval, you are targeting 99.9% of the periods to be in healthy state.

After you have created an SLO, you can retrieve error budget reports for it. An error budget is the number of periods or amount of time that your service can accumulate during an interval before your overall SLO budget health is breached and the SLO is considered to be unmet. for example, an SLO with a threshold that 99.95% of requests must be completed under 2000ms every month translates to an error budget of 21.9 minutes of downtime per month.

When you call this operation, Application Signals creates the AWSServiceRoleForCloudWatchApplicationSignals service-linked role, if it doesn't already exist in your account. This service- linked role has the following permissions:

  • xray:GetServiceGraph

  • logs:StartQuery

  • logs:GetQueryResults

  • cloudwatch:GetMetricData

  • cloudwatch:ListMetrics

  • tag:GetResources

  • autoscaling:DescribeAutoScalingGroups

You can easily set SLO targets for your applications that are discovered by Application Signals, using critical metrics such as latency and availability. You can also set SLOs against any CloudWatch metric or math expression that produces a time series.

For more information about SLOs, see Service level objectives (SLOs).

TagResource

$result = $client->tagResource([/* ... */]);
$promise = $client->tagResourceAsync([/* ... */]);

Assigns one or more tags (key-value pairs) to the specified CloudWatch resource, such as a service level objective.

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 Amazon Web Services and are interpreted strictly as strings of characters.

You can use the 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.

Dimension

Description

A dimension is a name/value pair that is part of the identity of a metric. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new variation of that metric. For example, many Amazon EC2 metrics publish InstanceId as a dimension name, and the actual instance ID as the value for that dimension.

You can assign up to 30 dimensions to a metric.

Members
Name
Required: Yes
Type: string

The name of the dimension. Dimension names must contain only ASCII characters, must include at least one non-whitespace character, and cannot start with a colon (:). ASCII control characters are not supported as part of dimension names.

Members
AttainmentGoal
Type: double

The threshold that determines if the goal is being met. An attainment goal is the ratio of good periods that meet the threshold requirements to the total periods within the interval. For example, an attainment goal of 99.9% means that within your interval, you are targeting 99.9% of the periods to be in healthy state.

If you omit this parameter, 99 is used to represent 99% as the attainment goal.

Interval
Type: Interval structure

The time period used to evaluate the SLO. It can be either a calendar interval or rolling interval.

If you omit this parameter, a rolling interval of 7 days is used.

WarningThreshold

MetricDataQuery

Description

Use this structure to define a metric or metric math expression that you want to use as for a service level objective.

Each MetricDataQuery in the MetricDataQueries array specifies either a metric to retrieve, or a metric math expression to be performed on retrieved metrics. A single MetricDataQueries array can include as many as 20 MetricDataQuery structures in the array. The 20 structures can include as many as 10 structures that contain a MetricStat parameter to retrieve a metric, and as many as 10 structures that contain the Expression parameter to perform a math expression. Of those Expression structures, exactly one must have true as the value for ReturnData. The result of this expression used for the SLO.

For more information about metric math expressions, see CloudWatchUse metric math.

Within each MetricDataQuery object, you must specify either Expression or MetricStat but not both.

Members
AccountId
Type: string

The ID of the account where this metric is located. If you are performing this operatiion in a monitoring account, use this to specify which source account to retrieve this metric from.

Expression
Type: string

This field can contain a metric math expression to be performed on the other metrics that you are retrieving within this MetricDataQueries structure.

A math expression can use the Id of the other metrics or queries to refer to those metrics, and can also use the Id of other expressions to use the result of those expressions. For more information about metric math expressions, see Metric Math Syntax and Functions in the Amazon CloudWatch User Guide.

Within each MetricDataQuery object, you must specify either Expression or MetricStat but not both.

Id
Required: Yes
Type: string

A short name used to tie this object to the results in the response. This Id must be unique within a MetricDataQueries array. If you are performing math expressions on this set of data, this name represents that data and can serve as a variable in the metric math expression. The valid characters are letters, numbers, and underscore. The first character must be a lowercase letter.

Label
Type: string

A human-readable label for this metric or expression. This is especially useful if this is an expression, so that you know what the value represents. If the metric or expression is shown in a CloudWatch dashboard widget, the label is shown. If Label is omitted, CloudWatch generates a default.

You can put dynamic expressions into a label, so that it is more descriptive. For more information, see Using Dynamic Labels.

MetricStat
Type: MetricStat structure

A metric to be used directly for the SLO, or to be used in the math expression that will be used for the SLO.

Within one MetricDataQuery object, you must specify either Expression or MetricStat but not both.

Period
Type: int

The granularity, in seconds, of the returned data points for this metric. For metrics with regular resolution, a period can be as short as one minute (60 seconds) and must be a multiple of 60. For high-resolution metrics that are collected at intervals of less than one minute, the period can be 1, 5, 10, 30, 60, or any multiple of 60. High-resolution metrics are those metrics stored by a PutMetricData call that includes a StorageResolution of 1 second.

If the StartTime parameter specifies a time stamp that is greater than 3 hours ago, you must specify the period as follows or no data points in that time range is returned:

  • Start time between 3 hours and 15 days ago - Use a multiple of 60 seconds (1 minute).

  • Start time between 15 and 63 days ago - Use a multiple of 300 seconds (5 minutes).

  • Start time greater than 63 days ago - Use a multiple of 3600 seconds (1 hour).

ReturnData
Type: boolean

Use this only if you are using a metric math expression for the SLO. Specify true for ReturnData for only the one expression result to use as the alarm. For all other metrics and expressions in the same CreateServiceLevelObjective operation, specify ReturnData as false.
