Description

Watch live XEvent Data as it happens. This command runs until you stop the session, kill the PowerShell session, or Ctrl-C.

Syntax

Watch-DbaXESession
    [[-SqlInstance] <DbaInstanceParameter>]
    [[-SqlCredential] <PSCredential>]
    [[-Session] <String>]
    [[-InputObject] <Session[]>]
    [-Raw]
    [-EnableException]
    [<CommonParameters>]

Examples

Example: 1

PS C:\> Watch-DbaXESession -SqlInstance sql2017 -Session system_health

Shows events for the system_health session as it happens.

Example: 2

PS C:\> Watch-DbaXESession -SqlInstance sql2017 -Session system_health | Export-Csv -NoTypeInformation -Path C:\temp\system_health.csv

Exports live events to CSV. Ctrl-C may not not cancel out of it - fastest way is to stop the session.

Example: 3

PS C:\> Get-DbaXESession -SqlInstance sql2017 -Session system_health | Start-DbaXESession | Watch-DbaXESession | Export-Csv -NoTypeInformation -Path C:\temp\system_health.csv

Exports live events to CSV. Ctrl-C may not not cancel out of this. The fastest way to do so is to stop the session.

Optional 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.

-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.

-Session

Only return a specific session. Options for this parameter are auto-populated from the server.

-InputObject

Accepts an XESession object returned by Get-DbaXESession.

-Raw

If this switch is enabled, the enumeration object is returned.

-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.
