Synopsis

Calls the Amazon Lightsail GetDistributionMetricData API operation.

Syntax

Get-LSDistributionMetricData
-DistributionName <String>

-MetricName <DistributionMetricName>
-Period <Int32>
-StartTime <DateTime>
-Statistic <String[]>
-Unit <MetricUnit>
-Select <String>

Description

Returns the data points of a specific metric for an Amazon Lightsail content delivery network (CDN) distribution. Metrics report the utilization of your resources, and the error counts generated by them. Monitor and collect metric data regularly to maintain the reliability, availability, and performance of your resources.

Parameters

-DistributionName <String>
The name of the distribution for which to get metric data.Use the GetDistributions action to get a list of distribution names that you can specify.
Required?True
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-EndTime <DateTime>
The end of the time interval for which to get metric data.Constraints:
  • Specified in Coordinated Universal Time (UTC).
  • Specified in the Unix time format.For example, if you wish to use an end time of October 1, 2018, at 9 PM UTC, specify 1538427600 as the end time.
You can convert a human-friendly time to Unix time format using a converter like Epoch converter.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-MetricName <DistributionMetricName>
The metric for which you want to return information.Valid distribution metric names are listed below, along with the most useful statistics to include in your request, and the published unit value.
  • Requests - The total number of viewer requests received by your Lightsail distribution, for all HTTP methods, and for both HTTP and HTTPS requests.Statistics: The most useful statistic is Sum.Unit: The published unit is None.
  • BytesDownloaded - The number of bytes downloaded by viewers for GET, HEAD, and OPTIONS requests.Statistics: The most useful statistic is Sum.Unit: The published unit is None.
  • BytesUploaded - The number of bytes uploaded to your origin by your Lightsail distribution, using POST and PUT requests.Statistics: The most useful statistic is Sum.Unit: The published unit is None.
  • TotalErrorRate - The percentage of all viewer requests for which the response's HTTP status code was 4xx or 5xx.Statistics: The most useful statistic is Average.Unit: The published unit is Percent.
  • 4xxErrorRate - The percentage of all viewer requests for which the response's HTTP status cod was 4xx. In these cases, the client or client viewer may have made an error. For example, a status code of 404 (Not Found) means that the client requested an object that could not be found.Statistics: The most useful statistic is Average.Unit: The published unit is Percent.
  • 5xxErrorRate - The percentage of all viewer requests for which the response's HTTP status code was 5xx. In these cases, the origin server did not satisfy the requests. For example, a status code of 503 (Service Unavailable) means that the origin server is currently unavailable.Statistics: The most useful statistic is Average.Unit: The published unit is Percent.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the DistributionName parameter. The -PassThru parameter is deprecated, use -Select '^DistributionName' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Period <Int32>
The granularity, in seconds, for the metric data points that will be returned.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-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.Lightsail.Model.GetDistributionMetricDataResponse). Specifying the name of a property of type Amazon.Lightsail.Model.GetDistributionMetricDataResponse 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)
-StartTime <DateTime>
The start of the time interval for which to get metric data.Constraints:
  • Specified in Coordinated Universal Time (UTC).
  • Specified in the Unix time format.For example, if you wish to use a start time of October 1, 2018, at 8 PM UTC, specify 1538424000 as the start time.
You can convert a human-friendly time to Unix time format using a converter like Epoch converter.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-Statistic <String[]>
The statistic for the metric.The following statistics are available:
  • Minimum - The lowest value observed during the specified period. Use this value to determine low volumes of activity for your application.
  • Maximum - The highest value observed during the specified period. Use this value to determine high volumes of activity for your application.
  • Sum - All values submitted for the matching metric added together. You can use this statistic to determine the total volume of a metric.
  • Average - The value of Sum / SampleCount during the specified period. By comparing this statistic with the Minimum and Maximum values, you can determine the full scope of a metric and how close the average use is to the Minimum and Maximum values. This comparison helps you to know when to increase or decrease your resources.
  • SampleCount - The count, or number, of data points used for the statistical calculation.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesStatistics
-Unit <MetricUnit>
The unit for the metric data request.Valid units depend on the metric data being requested. For the valid units with each available metric, see the metricName parameter.
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
Position?Named

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>
Used with SAML-based authentication when ProfileName references a SAML role profile.

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.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

-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?True (ByPropertyName)
