#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# function Start-DbaPfDataCollectorSet { <# .SYNOPSIS Starts Performance Monitor Data Collector Set. .DESCRIPTION Starts Performance Monitor Data Collector Set. .PARAMETER ComputerName The target computer. Defaults to localhost. .PARAMETER Credential Allows you to login to $ComputerName using alternative credentials. To use: $cred = Get-Credential, then pass $cred object to the -Credential parameter. .PARAMETER CollectorSet The name of the Collector Set to start. .PARAMETER NoWait If this switch is enabled, the collector is started and the results are returned immediately. .PARAMETER InputObject Accepts the object output by Get-DbaPfDataCollectorSet via the pipeline. .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Tags: PerfMon Author: Chrissy LeMaire (@cl), netnerds.net Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Start-DbaPfDataCollectorSet .EXAMPLE Start-DbaPfDataCollectorSet Attempts to start all ready Collectors on localhost. .EXAMPLE Start-DbaPfDataCollectorSet -ComputerName sql2017 Attempts to start all ready Collectors on localhost. .EXAMPLE Start-DbaPfDataCollectorSet -ComputerName sql2017, sql2016 -Credential (Get-Credential) -CollectorSet 'System Correlation' Starts the 'System Correlation' Collector on sql2017 and sql2016 using alternative credentials. .EXAMPLE Get-DbaPfDataCollectorSet -CollectorSet 'System Correlation' | Start-DbaPfDataCollectorSet Starts the 'System Correlation' Collector. #> [CmdletBinding()] param ( [DbaInstance[]]$ComputerName=$env:COMPUTERNAME, [PSCredential]$Credential, [Alias("DataCollectorSet")] [string[]]$CollectorSet, [parameter(ValueFromPipeline)] [object[]]$InputObject, [switch]$NoWait, [switch]$EnableException ) begin { $wait = $NoWait -eq $false $setscript = { $setname = $args[0]; $wait = $args[1] $collectorset = New-Object -ComObject Pla.DataCollectorSet $collectorset.Query($setname, $null) $null = $collectorset.Start($wait) } } process { if (-not $InputObject -or ($InputObject -and (Test-Bound -ParameterName ComputerName))) { foreach ($computer in $ComputerName) { $InputObject += Get-DbaPfDataCollectorSet -ComputerName $computer -Credential $Credential -CollectorSet $CollectorSet } } if ($InputObject) { if (-not $InputObject.DataCollectorSetObject) { Stop-Function -Message "InputObject is not of the right type.
