Synopsis
Calls the Amazon CloudWatch GetMetricData API operation.
Syntax
Get-CWMetricData-EndTime <DateTime>-MaxDatapoint <Int32>-MetricDataQuery <MetricDataQuery[]>-ScanBy <ScanBy>-StartTime <DateTime>-NextToken <String>
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
StorageResolutionof 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).
Parameters
-EndTime <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 then setting 12:07 or 12:29 as the EndTime. | Required? | False |
| Position? | Named |
| Accept pipeline input? | False |
-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.
| Required? | False |
| Position? | Named |
| Accept pipeline input? | False |
-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 |
| Position? | Named |
| Accept pipeline input? | False |
-NextToken <String>
Include this value, if it was returned by the previous call, to get the next set of data points.
Note: This parameter is only used if you are manually controlling output pagination of the service API call.

| 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>
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 then setting 12:07 or 12:29 as the StartTime. | Required? | False |
| Position? | Named |
| Accept pipeline input? | False |
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 |
| Position? | Named |
| Accept pipeline input? | False |
-Region <String>
The system name of the AWS region in which the operation should be invoked. For example, us-east-1, eu-west-1 etc.
| Required? | False |
| Position? | Named |
| Accept pipeline input? | False |
-EndpointUrl <String>
The endpoint to make the call against.
Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.
| Required? | False |
| Position? | Named |
| Accept pipeline input? | False |
Inputs
This cmdlet does not accept pipeline input.
Outputs
This cmdlet returns a collection of MetricDataResult objects.
The service call response (type Amazon.CloudWatch.Model.GetMetricDataResponse) can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.
Additionally, the following properties are added as Note properties to the service response type instance for the cmdlet entry in the $AWSHistory stack: NextToken (type System.String)
