CloudWatch: Get-CWMetricData Cmdlet | AWS Tools for PowerShell

Synopsis

Calls the Amazon CloudWatch GetMetricData API operation.

Syntax

Get-CWMetricData
-UtcEndTime <DateTime>
-MaxDatapoint <Int32>
-MetricDataQuery <MetricDataQuery[]>
-ScanBy <ScanBy>
-UtcStartTime <DateTime>
-EndTime <DateTime>
-NextToken <String>
-StartTime <DateTime>

Description

You can use the GetMetricData API to retrieve as many as 100 different metrics in a single request, with a total of as many as 100,800 datapoints. 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 in the Amazon CloudWatch User Guide. Calls to the GetMetricData API have a different pricing structure than calls to GetMetricStatistics. For more information about pricing, see Amazon CloudWatch Pricing. Amazon CloudWatch retains metric data as follows:

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 StorageResolution of 1.
Data points with a period of 60 seconds (1-minute) are available for 15 days.
Data points with a period of 300 seconds (5-minute) are available for 63 days.
Data points with a period of 3600 seconds (1 hour) are available for 455 days (15 months).

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.

Parameters

-EndTime <DateTime>

This property is deprecated. Setting this property results in non-UTC DateTimes not being marshalled correctly. Use EndTimeUtc instead. Setting either EndTime or EndTimeUtc results in both EndTime and EndTimeUtc being assigned, the latest assignment to either one of the two property is reflected in the value of both. EndTime is provided for backwards compatibility only and assigning a non-Utc DateTime to it results in the wrong timestamp being passed to the service.The time stamp indicating the latest data to be returned.For better performance, specify StartTime and EndTime values that align with the value of the metric's Period and sync up with the beginning and end of an hour. For example, if the Period of a metric is 5 minutes, specifying 12:05 or 12:30 as EndTime can get a faster response from CloudWatch than setting 12:07 or 12:29 as the EndTime.This parameter is deprecated.

-MaxDatapoint <Int32>

The maximum number of data points the request should return before paginating. If you omit this, the default of 100,800 is used.

Accept pipeline input?	False
Aliases	MaxDatapoints

-MetricDataQuery <MetricDataQuery[]>

The metric queries to be returned. A single GetMetricData call can include as many as 100 MetricDataQuery structures. Each of these structures can specify either a metric to retrieve, or a math expression to perform on retrieved data.

Required?	False

Accept pipeline input?	False
Aliases	MetricDataQueries

-NextToken <String>

Include this value, if it was returned by the previous call, to get the next set of data points.

Required?	False
Position?	Named
Accept pipeline input?	False

-ScanBy <ScanBy>

The order in which data points should be returned. TimestampDescending returns the newest data first and paginates when the MaxDatapoints limit is reached. TimestampAscending returns the oldest data first and paginates when the MaxDatapoints limit is reached.

Required?	False
Position?	Named
Accept pipeline input?	False

-StartTime <DateTime>

This property is deprecated. Setting this property results in non-UTC DateTimes not being marshalled correctly. Use StartTimeUtc instead. Setting either StartTime or StartTimeUtc results in both StartTime and StartTimeUtc being assigned, the latest assignment to either one of the two property is reflected in the value of both. StartTime is provided for backwards compatibility only and assigning a non-Utc DateTime to it results in the wrong timestamp being passed to the service.The time stamp indicating the earliest data to be returned.For better performance, specify StartTime and EndTime values that align with the value of the metric's Period and sync up with the beginning and end of an hour. For example, if the Period of a metric is 5 minutes, specifying 12:05 or 12:30 as StartTime can get a faster response from CloudWatch than setting 12:07 or 12:29 as the StartTime.This parameter is deprecated.

Required?	False

-UtcEndTime <DateTime>

The time stamp indicating the latest data to be returned.For better performance, specify StartTime and EndTime values that align with the value of the metric's Period and sync up with the beginning and end of an hour. For example, if the Period of a metric is 5 minutes, specifying 12:05 or 12:30 as EndTime can get a faster response from CloudWatch than setting 12:07 or 12:29 as the EndTime.

-UtcStartTime <DateTime>

The time stamp indicating the earliest data to be returned.For better performance, specify StartTime and EndTime values that align with the value of the metric's Period and sync up with the beginning and end of an hour. For example, if the Period of a metric is 5 minutes, specifying 12:05 or 12:30 as StartTime can get a faster response from CloudWatch than setting 12:07 or 12:29 as the StartTime.

Common Credential and Region Parameters

-AccessKey <String>

The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.

Required?	False
Position?	Named
Accept pipeline input?	False

-Credential <AWSCredentials>

An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.

Required?	False
Position?	Named
Accept pipeline input?	False

-ProfileLocation <String>

Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)

If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.

If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.

As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.

Required?	False
Position?	Named
Accept pipeline input?	False

-ProfileName <String>

The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.

Required?	False
Position?	Named
Accept pipeline input?	False

-NetworkCredential <PSCredential>

Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.

Required?	False
Position?	Named
Accept pipeline input?	False

-SecretKey <String>

The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.

Required?	False
Position?	Named
Accept pipeline input?	False

-SessionToken <String>

The session token if the access and secret keys are temporary session-based credentials.

Required?	False
