Synopsis

Calls the AWS Performance Insights GetResourceMetrics API operation.

Syntax

Get-PIResourceMetric
-EndTime <DateTime>
-Identifier <String>
-MetricQuery <MetricQuery[]>
-PeriodAlignment <PeriodAlignment>
-PeriodInSecond <Int32>
-ServiceType <ServiceType>
-StartTime <DateTime>
-MaxResult <Int32>
-NextToken <String>
-Select <String>
-NoAutoIteration <SwitchParameter>
-ClientConfig <AmazonPIConfig>

Description

Retrieve Performance Insights metrics for a set of data sources over a time period. You can provide specific dimension groups and dimensions, and provide filtering criteria for each group. You must specify an aggregate function for each metric. Each response element returns a maximum of 500 bytes. For larger elements, such as SQL statements, only the first 500 bytes are returned.

This cmdlet automatically pages all available results to the pipeline - parameters related to iteration are only needed if you want to manually control the paginated output. To disable autopagination, use -NoAutoIteration. This cmdlet didn't autopaginate in V4, auto-pagination support was added in V5.

Parameters

-ClientConfig <AmazonPIConfig>
Amazon.PowerShell.Cmdlets.PI.AmazonPIClientCmdlet.ClientConfig
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-EndTime <DateTime>
The date and time specifying the end of the requested time series query range. The value specified is exclusive. Thus, the command returns data points less than (but not equal to) EndTime.The value for EndTime must be later than the value for StartTime.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-Identifier <String>
An immutable identifier for a data source that is unique for an Amazon Web Services Region. Performance Insights gathers metrics from this data source. In the console, the identifier is shown as ResourceID. When you call DescribeDBInstances, the identifier is returned as DbiResourceId.To use a DB instance as a data source, specify its DbiResourceId value. For example, specify db-ABCDEFGHIJKLMNOPQRSTU1VW2X.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-MaxResult <Int32>
The maximum number of items to return in the response.
Note: In AWSPowerShell and AWSPowerShell.NetCore this parameter is used to limit the total number of items returned by the cmdlet.
In AWS.Tools this parameter is simply passed to the service to specify how many items should be returned by each service call.
Pipe the output of this cmdlet into Select-Object -First to terminate retrieving data pages early and control the number of items returned.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesMaxItems, MaxResults
-MetricQuery <MetricQuery[]>
An array of one or more queries to perform. Each query must specify a Performance Insights metric and specify an aggregate function, and you can provide filtering criteria. You must append the aggregate function to the metric. For example, to find the average for the metric db.load you must use db.load.avg. Valid values for aggregate functions include .avg, .min, .max, and .sum. Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesMetricQueries
-NextToken <String>
An optional pagination token provided by a previous request. If this parameter is specified, the response includes only records beyond the token, up to the value specified by MaxRecords.
Note: This parameter is only used if you are manually controlling output pagination of the service API call.
'NextToken' is only returned by the cmdlet when '-Select *' is specified. In order to manually control output pagination, set '-NextToken' to null for the first call then set the 'NextToken' using the same property output from the previous call for subsequent calls.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NoAutoIteration <SwitchParameter>
By default the cmdlet will auto-iterate and retrieve all results to the pipeline by performing multiple service calls. If set, the cmdlet will retrieve only the next 'page' of results using the value of NextToken as the start point. This cmdlet didn't autopaginate in V4. To preserve the V4 autopagination behavior for all cmdlets, run Set-AWSAutoIterationMode -IterationMode v4.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PeriodAlignment <PeriodAlignment>
The returned timestamp which is the start or end time of the time periods. The default value is END_TIME.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PeriodInSecond <Int32>
The granularity, in seconds, of the data points returned from Performance Insights. A period can be as short as one second, or as long as one day (86400 seconds). Valid values are:
  • 1 (one second)
  • 60 (one minute)
  • 300 (five minutes)
  • 3600 (one hour)
  • 86400 (twenty-four hours)
If you don't specify PeriodInSeconds, then Performance Insights will choose a value for you, with a goal of returning roughly 100-200 data points in the response.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesPeriodInSeconds
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is '*'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.PI.Model.GetResourceMetricsResponse). Specifying the name of a property of type Amazon.PI.Model.GetResourceMetricsResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ServiceType <ServiceType>
The Amazon Web Services service for which Performance Insights returns metrics. Valid values are as follows:
  • RDS
  • DOCDB
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-StartTime <DateTime>
The date and time specifying the beginning of the requested time series query range. You can't specify a StartTime that is earlier than 7 days ago. By default, Performance Insights has 7 days of retention, but you can extend this range up to 2 years. The value specified is inclusive. Thus, the command returns data points equal to or greater than StartTime.The value for StartTime must be earlier than the value for EndTime.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)

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

Accept pipeline input?True (ByValue, ByPropertyName)
-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?True (ByPropertyName)
-NetworkCredential <PSCredential>

-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.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.

-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information.
