function Get-DbaPfCounter { <# .SYNOPSIS Gets Peformance Counters .DESCRIPTION Gets Peformance Counters .PARAMETER ComputerName The target computer. Defaults to localhost. .PARAMETER Credential Allows you to login to $ComputerName using alternative credentials. .PARAMETER CollectorSet The Collector Set name .PARAMETER Collector The Collector name .PARAMETER InputObject Enables piped results from Get-DbaPfDataCollectorSet .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Tags: PerfMon Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: GNU GPL v3 https://opensource.org/licenses/GPL-3.0 .LINK https://dbatools.io/Get-DbaPfCounter .EXAMPLE Get-DbaPfCounter Gets all counters for all collector sets on localhost .EXAMPLE Get-DbaPfCounter -ComputerName sql2017 Gets all counters for all collector sets on on sql2017 .EXAMPLE Get-DbaPfCounter -ComputerName sql2017, sql2016 -Credential (Get-Credential) -CollectorSet 'System Correlation' Gets all counters for 'System Correlation' Collector on sql2017 and sql2016 using alternative credentials .EXAMPLE Get-DbaPfDataCollectorSet -CollectorSet 'System Correlation' | Get-DbaPfDataCollector | Get-DbaPfCounter Gets all counters for 'System Correlation' Collector #> [CmdletBinding()] param ( [DbaInstance[]]$ComputerName = $env:COMPUTERNAME, [PSCredential]$Credential, [string[]]$CollectorSet, [string[]]$Collector, [parameter(ValueFromPipeline)] [object[]]$InputObject, [switch]$EnableException ) begin { $columns = 'ComputerName', 'Name', 'DataCollectorSet', 'Counters', 'DataCollectorType', 'DataSourceName', 'FileName', 'FileNameFormat', 'FileNameFormatPattern', 'LatestOutputLocation', 'LogAppend', 'LogCircular', 'LogFileFormat', 'LogOverwrite', 'SampleInterval', 'SegmentMaxRecords' } process { if ($InputObject.Credential -and (Test-Bound -ParameterName Credential -Not)) { $Credential = $InputObject.Credential } if (-not $InputObject -or ($InputObject -and (Test-Bound -ParameterName ComputerName))) { foreach ($computer in $ComputerName) { $InputObject += Get-DbaPfDataCollector -ComputerName $computer -Credential $Credential -CollectorSet $CollectorSet -Collector $Collector } } if (-not $InputObject.CollectorXml) { Stop-Function -Message "InputObject is not of the right type.
