Required Parameters

-SqlInstance

The target SQL Server instance or instances. You must have sysadmin access and server version must be SQL Server version 2008 or higher.

-Session

Only start specific Extended Events sessions.

-AllSessions

Start all Extended Events sessions on an instance, ignoring the packaged sessions: AlwaysOn_health, system_health, telemetry_xevents.

-InputObject

Internal parameter to support piping from Get-DbaXESession

Optional Parameters

-SqlCredential

Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential). Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported. For MFA support, please use Connect-DbaInstance.

-StartAt

Specifies a datetime at which the session will be started. This is done via a self-deleting schedule. The command returns immediately and returns the affected sessions in their current state.

-StopAt

Specifies a datetime at which the session will be stopped. This is done via a self-deleting schedule.

-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.

-WhatIf

If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

-Confirm

If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.
