.SYNOPSIS
Find Disabled indexes
.DESCRIPTION
This command will help you to find disabled indexes on a database or a list of databases.
.PARAMETER SqlInstance
The target SQL Server instance or instances.
.PARAMETER 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.
.PARAMETER Database
The database(s) to process. Options for this list are auto-populated from the server. If unspecified, all databases will be processed.
.PARAMETER ExcludeDatabase
Specifies the database(s) to exclude from processing. Options for this list are auto-populated from the server.
.PARAMETER NoClobber
If this switch is enabled, the output file will not be overwritten.
.PARAMETER Append
If this switch is enabled, content will be appended to the output file.
.PARAMETER 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.
.PARAMETER Confirm
If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.
.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.
