Removes all SQL Agent alerts on the localhost, localhost\namedinstance instances.

Example: 2
PS C:\> Remove-DbaAgentAlert -SqlInstance localhost -Alert MyDatabaseAlert

Example: 3
PS C:\> Get-DbaAgentAlert -SqlInstance SRV1 | Out-GridView -Title 'Select SQL Agent alert(s) to drop' -OutputMode Multiple | Remove-DbaAgentAlert

Using a pipeline this command gets all SQL Agent alerts on SRV1, lets the user select those to remove and then removes the selected SQL Agent alerts.

Required Parameters

-SqlInstance

The target SQL Server instance or instances.

Alias
Required True
Pipeline false
Default Value
-InputObject

Accepts SQL Agent alert objects from the pipeline, typically from Get-DbaAgentAlert.
Use this for selective removal operations where you first query alerts with specific criteria and then remove the filtered results.
Enables advanced scenarios like interactive selection using Out-GridView or complex filtering logic.

Alias
Required True
Pipeline true (ByValue)
Default Value

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.

Alias
Required False
Pipeline false
Default Value
-Alert

Specifies the names of specific SQL Agent alerts to remove from the target instances.
Use this when you need to remove particular alerts rather than all alerts on the server.
Accepts an array of alert names for bulk removal operations.

Alias
Required False
Pipeline false
Default Value
-ExcludeAlert

Excludes specific SQL Agent alerts from removal when processing all alerts on an instance.
Useful for bulk cleanup operations where you want to preserve certain critical alerts.
Only applies when the Alert parameter is not specified, allowing you to remove all alerts except those listed here.

Alias
Required False
Pipeline false
Default Value
-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.

Alias
Required False
Pipeline false
Default Value False
-WhatIf

Shows what would happen if the command were to run. No actions are actually performed.

Alias wi
Required False
Pipeline false
Default Value
-Confirm

Prompts you for confirmation before executing any changing operations within the command.
This is the default. Use -Confirm:$false to suppress these prompts.

Alias cf
Required False
Pipeline false
Default Value
