function Get-DbaLogShippingError { <# .SYNOPSIS Get-DbaLogShippingError returns all the log shipping errors that occurred .DESCRIPTION When your log shipping fails it's sometimes hard to see why is fails. Using this function you'll be able to find out what went wrong in a short amount of time. .PARAMETER SqlInstance SQL Server instance. You must have sysadmin access and server version must be SQL Server version 2000 or greater. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER Database Allows you to filter the results to only return the databases you're interested in. This can be one or more values separated by commas. This is not a wildcard and should be the exact database name. See examples for more info. .PARAMETER ExcludeDatabase Allows you to filter the results to only return the databases you're not interested in. This can be one or more values separated by commas. This is not a wildcard and should be the exact database name. .PARAMETER Action Filter to get the log shipping action that has occurred like Backup, Copy, Restore. By default all the actions are returned. .PARAMETER DateTimeFrom Filter the results based on the date starting from datetime X .PARAMETER DateTimeTo Filter the results based on the date ending with datetime X .PARAMETER Primary Allows to filter the results to only return values that apply to the primary instance. .PARAMETER Secondary Allows to filter the results to only return values that apply to the secondary instance. .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: LogShipping Author: Sander Stad (@sqlstad, sqlstad.nl) Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaLogShippingError .EXAMPLE Get-DbaLogShippingError -SqlInstance sql1 Get all the log shipping errors that occurred .EXAMPLE Get-DbaLogShippingError -SqlInstance sql1 -Action Backup Get the errors that have something to do with the backup of the databases .EXAMPLE Get-DbaLogShippingError -SqlInstance sql1 -Secondary Get the errors that occurred on the secondary instance. This will return the copy of the restore actions because those only occur on the secondary instance .EXAMPLE Get-DbaLogShippingError -SqlInstance sql1 -DateTimeFrom "01/05/2018" Get the errors that have occurred from "01/05/2018". This can also be of format "yyyy-MM-dd" .EXAMPLE Get-DbaLogShippingError -SqlInstance sql1 -Secondary -DateTimeFrom "01/05/2018" -DateTimeTo "2018-01-07" Get the errors that have occurred between "01/05/2018" and "01/07/2018".
