function Get-DbaPfDataCollectorCounterSample { <# .SYNOPSIS Gets Performance Counter Samples. .DESCRIPTION Gets Performance Counter Samples. .PARAMETER ComputerName The target computer. Defaults to localhost. .PARAMETER Credential Allows you to login to servers using alternative credentials. To use: $scred = Get-Credential, then pass $scred object to the -Credential parameter. .PARAMETER CollectorSet The Collector Set name. .PARAMETER Collector The Collector name. .PARAMETER Counter The Counter name. This must be in the form of '\Processor(_Total)\% Processor Time'. .PARAMETER Continuous If this switch is enabled, samples will be retrieved continuously until you press CTRL+C. By default, this command gets only one counter sample. You can use the SampleInterval parameter to set the interval for continuous sampling. .PARAMETER ListSet Gets the specified performance counter sets on the computers. Enter the names of the counter sets. Wildcards are permitted. .PARAMETER MaxSamples Specifies the number of samples to get from each counter. The default is 1 sample. To get samples continuously (no maximum sample size), use the Continuous parameter. To collect a very large data set, consider running a Get-DbaPfDataCollectorCounterSample command as a Windows PowerShell background job. .PARAMETER SampleInterval Specifies the time between samples in seconds. The minimum value and the default value are 1 second. .PARAMETER InputObject Accepts the object output by Get-DbaPfDataCollectorCounter via the pipeline. .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Tags: Performance, DataCollector, PerfCounter Author: Chrissy LeMaire (@cl), netnerds.net Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaPfDataCollectorCounterSample .EXAMPLE PS C:\> Get-DbaPfDataCollectorCounterSample Gets a single sample for all counters for all Collector Sets on localhost. .EXAMPLE PS C:\> Get-DbaPfDataCollectorCounterSample -Counter '\Processor(_Total)\% Processor Time' Gets a single sample for all counters for all Collector Sets on localhost. .EXAMPLE PS C:\> Get-DbaPfDataCollectorCounter -ComputerName sql2017, sql2016 | Out-GridView -PassThru | Get-DbaPfDataCollectorCounterSample -MaxSamples 10 Gets 10 samples for all counters for all Collector Sets for servers sql2016 and sql2017. .EXAMPLE PS C:\> Get-DbaPfDataCollectorCounterSample -ComputerName sql2017 Gets a single sample for all counters for all Collector Sets on sql2017. .EXAMPLE PS C:\> Get-DbaPfDataCollectorCounterSample -ComputerName sql2017, sql2016 -Credential ad\sqldba -CollectorSet 'System Correlation' Gets a single sample for all counters for the 'System Correlation' CollectorSet on sql2017 and sql2016 using alternative credentials. .EXAMPLE PS C:\> Get-DbaPfDataCollectorCounterSample -CollectorSet 'System Correlation' Gets a single sample for all counters for the 'System Correlation' CollectorSet. #> [CmdletBinding()] param ( [DbaInstance[]]$ComputerName = $env:COMPUTERNAME, [PSCredential]$Credential, [Alias("DataCollectorSet")] [string[]]$CollectorSet, [Alias("DataCollector")] [string[]]$Collector, [string[]]$Counter, [switch]$Continuous, [switch[]]$ListSet, [int]$MaxSamples, [int]$SampleInterval, [parameter(ValueFromPipeline)] [object[]]$InputObject, [switch]$EnableException ) process { if ($InputObject.Credential -and (Test-Bound -ParameterName Credential -Not)) { $Credential = $InputObject.Credential } if ($InputObject.Counter -and (Test-Bound -ParameterName Counter -Not)) { $Counter = $InputObject.Counter } if (-not $InputObject -or ($InputObject -and (Test-Bound -ParameterName ComputerName))) { foreach ($computer in $ComputerName) { $InputObject += Get-DbaPfDataCollectorCounter -ComputerName $computer -Credential $Credential -CollectorSet $CollectorSet -Collector $Collector } } if ($InputObject) { if (-not $InputObject.CounterObject) { Stop-Function -Message "InputObject is not of the right type.
