function Get-DbaNetworkActivity { <# .SYNOPSIS Gets the Current traffic on every Network Interface on a computer. .DESCRIPTION Gets the Current traffic on every Network Interface on a computer. See https://msdn.microsoft.com/en-us/library/aa394293(v=vs.85).aspx Requires Local Admin rights on destination computer(s). .PARAMETER ComputerName The target SQL Server instance or instances. .PARAMETER Credential Credential object used to connect to the computer as a different user. .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: Server, Management, Network Author: Klaas Vandenberghe (@PowerDBAKlaas) Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaNetworkActivity .EXAMPLE PS C:\> Get-DbaNetworkActivity -ComputerName sqlserver2014a Gets the Current traffic on every Network Interface on computer sqlserver2014a. .EXAMPLE PS C:\> 'sql1','sql2','sql3' | Get-DbaNetworkActivity Gets the Current traffic on every Network Interface on computers sql1, sql2 and sql3. .EXAMPLE PS C:\> Get-DbaNetworkActivity -ComputerName sql1,sql2 Gets the Current traffic on every Network Interface on computers sql1 and sql2. #> [CmdletBinding()] param ( [parameter(ValueFromPipeline)] [Alias("cn", "host", "Server")] [string[]]$ComputerName = $env:COMPUTERNAME, [PSCredential] $Credential, [switch]$EnableException ) begin { $ComputerName = $ComputerName | ForEach-Object { $_.split("\")[0] } | Select-Object -Unique $sessionoption = New-CimSessionOption -Protocol DCom } process { foreach ($computer in $ComputerName) { $Server = Resolve-DbaNetworkName -ComputerName $Computer -Credential $credential if ( $Server.FullComputerName ) { $Computer = $server.FullComputerName Write-Message -Level Verbose -Message "Creating CIMSession on $computer over WSMan" $CIMsession = New-CimSession -ComputerName $Computer -ErrorAction SilentlyContinue -Credential $Credential if ( -not $CIMSession ) { Write-Message -Level Verbose -Message "Creating CIMSession on $computer over WSMan failed.
