#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# function Start-DbaXESmartTarget { <# .SYNOPSIS XESmartTarget runs as a client application for an Extended Events session running on a SQL Server instance. .DESCRIPTION XESmartTarget offers the ability to set up complex actions in response to Extended Events captured in sessions, without writing a single line of code. See more at https://github.com/spaghettidba/XESmartTarget/wiki .PARAMETER SqlInstance Target SQL Server. You must have sysadmin access and server version must be SQL Server version 2008 or higher. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER Session Name of the Extended Events session to attach to. You can monitor a single session with an instance of XESmartTarget. In case you need to perform action on multiple sessions, run an additional instance of XESmartTarget, with its own configuration file. .PARAMETER Database Specifies the name of the database that contains the target table. .PARAMETER FailOnProcessingError If this switch is enabled, the a processing error will trigger a failure. .PARAMETER Responder The list of responses can include zero or more Response objects, each to be configured by specifying values for their public members. .PARAMETER Template Path to the dbatools built-in templates .PARAMETER NotAsJob If this switch is enabled, output will be sent to screen indefinitely. BY default, a job will be run in the background. .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: ExtendedEvent, XE, XEvent Author: Chrissy LeMaire (@cl),
