To install sp_WhoIsActive to sqlserver2014a’s master database using Windows Authentication to login.

Install-DbaWhoIsActive -SqlServer sqlserver2014a -Database master

If no database is specified, you will be presented with a dialog box asking which database on sqlserver2014a you want to install the procedure within. If you’d like to use SQL authentication instead of Windows authentication, use the SqlCredential parameter.

$cred = Get-Credential
Install-DbaWhoIsActive -SqlServer sqlserver2014a -SqlCredential $cred

This command doesn’t support passing both servers and default database, but you can accomplish the same thing by passing an array and specifying a database.

$servers = Get-SqlRegisteredServerName sqlserver
Install-DbaWhoIsActive -SqlServer $servers -Database master


From PowerShell, execute Get-Help Install-DbaWhoIsActive -Detailed for more information on this function.
