Get-DbaDump

Synopsis

Retrieves SQL Server memory dump file information from sys.dm_server_memory_dumps DMV.

Description

Queries the sys.dm_server_memory_dumps dynamic management view to return details about memory dump files (.mdmp) generated by SQL Server. Memory dumps are created when SQL Server encounters crashes, assertion failures, or other critical errors that require investigation. This function helps DBAs quickly identify when dumps have been generated, their size, and creation time, which is essential for troubleshooting server stability issues and working with Microsoft Support for crash analysis.

Required Parameters

-SqlInstance

The target SQL Server instance or instances. This can be a collection and receive pipeline input to allow the function to be executed against multiple SQL Server instances.

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.

-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.
