function Invoke-DbaDiagnosticQuery { <# .SYNOPSIS Invoke-DbaDiagnosticQuery runs the scripts provided by Glenn Berry's DMV scripts on specified servers .DESCRIPTION This is the main function of the Sql Server Diagnostic Queries related functions in dbatools. The diagnostic queries are developed and maintained by Glenn Berry and they can be found here along with a lot of documentation: http://www.sqlskills.com/blogs/glenn/category/dmv-queries/ The most recent version of the diagnostic queries are included in the dbatools module. But it is possible to download a newer set or a specific version to an alternative location and parse and run those scripts. It will run all or a selection of those scripts on one or multiple servers and return the result as a PowerShell Object .PARAMETER SqlInstance The target SQL Server. Can be either a string or SMO server .PARAMETER SqlCredential Allows alternative Windows or SQL login credentials to be used .PARAMETER Path Alternate path for the diagnostic scripts .PARAMETER Database The database(s) to process. If unspecified, all databases will be processed .PARAMETER ExcludeDatabase The database(s) to exclude .PARAMETER UseSelectionHelper Provides a gridview with all the queries to choose from and will run the selection made by the user on the Sql Server instance specified. .PARAMETER QueryName Only run specific query .PARAMETER InstanceOnly Run only instance level queries .PARAMETER DatabaseSpecific Run only database level queries .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. .PARAMETER Confirm Prompts to confirm certain actions .PARAMETER WhatIf Shows what would happen if the command would execute, but does not actually perform the command .NOTES Tags: Database, DMV Author: André Kamman (@AndreKamman), http://clouddba.io Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: GNU GPL v3 https://opensource.org/licenses/GPL-3.0 .LINK https://dbatools.io/Invoke-DbaDiagnosticQuery .EXAMPLE Invoke-DbaDiagnosticQuery -SqlInstance sql2016 Run the selection made by the user on the Sql Server instance specified. .EXAMPLE Invoke-DbaDiagnosticQuery -SqlInstance sql2016 -UseSelectionHelper | Export-DbaDiagnosticQuery -Path C:\temp\gboutput Provides a gridview with all the queries to choose from and will run the selection made by the user on the SQL Server instance specified.
