function Get-DbaProcess { <# .SYNOPSIS This command displays SQL Server processes. .DESCRIPTION This command displays processes associated with a spid, login, host, program or database. Thanks to Michael J Swart at https://sqlperformance.com/2017/07/sql-performance/find-database-connection-leaks for the query to get the last executed SQL statement, minutesasleep and host process ID. .PARAMETER SqlInstance The SQL Server instance to connect to. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER Spid Specifies one or more process IDs (Spid) to be displayed. Options for this parameter are auto-populated from the server. .PARAMETER Login Specifies one or more Login names with active processes to look for. Options for this parameter are auto-populated from the server. .PARAMETER Hostname Specifies one or more hostnames with active processes to look for. Options for this parameter are auto-populated from the server. .PARAMETER Program Specifies one or more program names with active processes to look for. Options for this parameter are auto-populated from the server. .PARAMETER Database Specifies one or more databases with active processes to look for. Options for this parameter are auto-populated from the server. .PARAMETER ExcludeSpid Specifies one ore more process IDs to exclude from display. Options for this parameter are auto-populated from the server. This is the last filter to run, so even if a Spid matches another filter, it will be excluded by this filter. .PARAMETER NoSystemSpid If this switch is enabled, system Spids will be ignored. .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: Process, Session, ActivityMonitor 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/Get-DbaProcess .EXAMPLE PS C:\> Get-DbaProcess -SqlInstance sqlserver2014a -Login base\ctrlb, sa Shows information about the processes for base\ctrlb and sa on sqlserver2014a. Windows Authentication is used in connecting to sqlserver2014a. .EXAMPLE PS C:\> Get-DbaProcess -SqlInstance sqlserver2014a -SqlCredential $credential -Spid 56, 77 Shows information about the processes for spid 56 and 57. Uses alternative (SQL or Windows) credentials to authenticate to sqlserver2014a. .EXAMPLE PS C:\> Get-DbaProcess -SqlInstance sqlserver2014a -Program 'Microsoft SQL Server Management Studio' Shows information about the processes that were created in Microsoft SQL Server Management Studio. .EXAMPLE PS C:\> Get-DbaProcess -SqlInstance sqlserver2014a -Host workstationx, server100 Shows information about the processes that were initiated by hosts (computers/clients) workstationx and server 1000. #> [CmdletBinding()] param ( [parameter(Mandatory, ValueFromPipeline)] [Alias("ServerInstance",
