#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# function Get-DbaPfDataCollectorCounter { <# .SYNOPSIS Gets Performance Counters. .DESCRIPTION Gets Performance Counters. .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 $scred object to the -Credential parameter. .PARAMETER CollectorSet The Collector Set name. .PARAMETER Collector The Collector name. .PARAMETER Counter The Counter name to capture. This must be in the form of '\Processor(_Total)\% Processor Time'. .PARAMETER InputObject Accepts the object output by Get-DbaPfDataCollectorSet via the pipeline. .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Tags: Performance, DataCollector, PerfCounter Author: Chrissy LeMaire (@cl), netnerds.net Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaPfDataCollectorCounter .EXAMPLE Get-DbaPfDataCollectorCounter Gets all counters for all Collector Sets on localhost. .EXAMPLE Get-DbaPfDataCollectorCounter -ComputerName sql2017 Gets all counters for all Collector Sets on on sql2017. .EXAMPLE Get-DbaPfDataCollectorCounter -ComputerName sql2017 -Counter '\Processor(_Total)\% Processor Time' Gets the '\Processor(_Total)\% Processor Time' counter on sql2017. .EXAMPLE Get-DbaPfDataCollectorCounter -ComputerName sql2017, sql2016 -Credential (Get-Credential) -CollectorSet 'System Correlation' Gets all counters for the 'System Correlation' CollectorSet on sql2017 and sql2016 using alternative credentials. .EXAMPLE Get-DbaPfDataCollectorSet -CollectorSet 'System Correlation' | Get-DbaPfDataCollector | Get-DbaPfDataCollectorCounter Gets all counters for the 'System Correlation' CollectorSet. #> [CmdletBinding()] param ( [DbaInstance[]]$ComputerName = $env:COMPUTERNAME, [PSCredential]$Credential, [Alias("DataCollectorSet")] [string[]]$CollectorSet, [Alias("DataCollector")] [string[]]$Collector, [string[]]$Counter, [parameter(ValueFromPipeline)] [object[]]$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 $Collector } } if ($InputObject) { if (-not $InputObject.DataCollectorObject) { Stop-Function -Message "InputObject is not of the right type.
