function Get-DbaAgentAlertCategory { <# .SYNOPSIS Get-DbaAgentAlertCategory retrieves the alert categories. .DESCRIPTION Get-DbaAgentAlertCategory makes it possible to retrieve the alert categories. .PARAMETER 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. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER Category The name of the category to filter out. If no category is used all categories will be returned. .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. .NOTES Tags: Agent, Alert, AlertCategory Author: Patrick Flynn (@sqllensman) Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaAgentAlertCategory .EXAMPLE PS C:\> Get-DbaAgentAlertCategory -SqlInstance sql1 Return all the agent alert categories. .EXAMPLE PS C:\> Get-DbaAgentAlertCategory -SqlInstance sql1 -Category 'Severity Alert' Return all the agent alert categories that have the name 'Severity Alert'. #> [CmdletBinding()] param ( [parameter(Mandatory, ValueFromPipeline)] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [string[]]$Category, [switch]$EnableException ) process { foreach ($instance in $SqlInstance) { try { $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential } catch { Stop-Function -Message "Error occurred while establishing connection to $instance" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } $alertCategories = $server.JobServer.AlertCategories if (Test-Bound -ParameterName Category) { $alertCategories = $alertCategories | Where-Object { $_.Name -in $Category } } $defaults = 'ComputerName', 'InstanceName', 'SqlInstance', 'Name', 'ID', 'AlertCount' try { foreach ($cat in $alertCategories) { $alertCount = ($server.JobServer.Alerts | Where-Object {$_.CategoryName -eq $cat.Name}).Count Add-Member -Force -InputObject $cat -MemberType NoteProperty -Name ComputerName -value $server.ComputerName Add-Member -Force -InputObject $cat -MemberType NoteProperty -Name InstanceName -value $server.ServiceName Add-Member -Force -InputObject $cat -MemberType NoteProperty -Name SqlInstance -value $server.DomainInstanceName Add-Member -Force -InputObject $cat -MemberType NoteProperty -Name AlertCount -Value $alertCount Select-DefaultView -InputObject $cat -Property $defaults } } catch { Stop-Function -Message "Something went wrong getting the alert category $cat on $instance" -Target $cat -Continue -ErrorRecord $_ } } } } |
