function Add-DbaPfDataCollectorCounter { <# .SYNOPSIS Adds a Performance Data Collector Counter. .DESCRIPTION Adds a Performance Data Collector Counter. .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 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 InputObject Accepts the object output by Get-DbaPfDataCollector via the pipeline. .PARAMETER WhatIf If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run. .PARAMETER Confirm If this switch is enabled, you will be prompted for confirmation before executing any operations that change state. .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/Add-DbaPfDataCollectorCounter .EXAMPLE PS C:\> Add-DbaPfDataCollectorCounter -ComputerName sql2017 -CollectorSet 'System Correlation' -Collector DataCollector01 -Counter '\LogicalDisk(*)\Avg.
