function Test-DbaLogShippingStatus { <# .SYNOPSIS Test-DbaLogShippingStatus returns the status of your log shipping databases .DESCRIPTION Most of the time your log shipping "just works". Checking your log shipping status can be done really easy with this function. Make sure you're connecting to the monitoring instance of your log shipping infrastructure. The function will return the status for a database. This can be one or more messages in a comma separated list. If everything is OK with the database than you should only see the message "All OK". .PARAMETER SqlInstance SQL Server instance. You must have sysadmin access and server version must be SQL Server version 2000 or greater. .PARAMETER SqlCredential Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. To use: $scred = Get-Credential, then pass $scred object to the -SqlCredential parameter. To connect as a different Windows user, run PowerShell as that user. .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 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 Simple By default all the information will be returned. If this parameter is used you get an overview with the SQL Instance, Database, Instance Type and the status .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 Original Author: Sander Stad (@sqlstad, sqlstad.nl) Tags: LogShipping 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/Test-DbaLogShippingStatus .EXAMPLE Test-DbaLogShippingStatus -SqlInstance sql1 Retrieves the log ship informaton from sql1 and displays all the information present including the status. .EXAMPLE Test-DbaLogShippingStatus -SqlInstance sql1 -Database AdventureWorks2014 Retrieves the log ship information for just the database AdventureWorks. .EXAMPLE Test-DbaLogShippingStatus -SqlInstance sql1 -Primary Retrieves the log ship information and only returns the information for the databases on the primary instance. .EXAMPLE Test-DbaLogShippingStatus -SqlInstance sql1 -Secondary Retrieves the log ship information and only returns the information for the databases on the secondary instance. .EXAMPLE Test-DbaLogShippingStatus -SqlInstance sql1 -Simple Retrieves the log ship information and only returns the columns SQL Instance, Database, Instance Type and Status #> [CmdletBinding()] param ( [parameter(Mandatory = $true, ValueFromPipeline = $true)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [string[]]$Database, [string[]]$ExcludeDatabase, [switch]$Simple, [switch]$Primary, [switch]$Secondary, [switch][Alias('Silent')]$EnableException ) begin { # Create array list to hold the results $collection = New-Object System.Collections.ArrayList # Setup the query [string[]]$query = " IF ( OBJECT_ID('tempdb..#logshippingstatus') ) IS NOT NULL BEGIN DROP TABLE #logshippingstatus; END; CREATE TABLE #logshippingstatus ( Status BIT , IsPrimary BIT , Server VARCHAR(100) , DatabaseName VARCHAR(100) , TimeSinceLastBackup INT , LastBackupFile VARCHAR(255) , BackupThresshold INT , IsBackupAlertEnabled BIT , TimeSinceLastCopy INT , LastCopiedFile VARCHAR(255) , TimeSinceLastRestore INT , LastRestoredFile VARCHAR(255) , LastRestoredLatency INT , RestoreThresshold INT , IsRestoreAlertEnabled BIT ); INSERT INTO #logshippingstatus ( Status , IsPrimary , Server , DatabaseName , TimeSinceLastBackup , LastBackupFile , BackupThresshold , IsBackupAlertEnabled , TimeSinceLastCopy , LastCopiedFile , TimeSinceLastRestore , LastRestoredFile , LastRestoredLatency , RestoreThresshold , IsRestoreAlertEnabled ) EXEC master.sys.sp_help_log_shipping_monitor" $select = "SELECT * FROM #logshippingstatus" if ($Database -or $ExcludeDatabase) { if ($database) { $where += "DatabaseName IN ('$($Database -join ''',''')')" } elseif ($ExcludeDatabase) { $where += "DatabaseName NOT IN ('$($ExcludeDatabase -join ''',''')')" } $select = "$select WHERE $where" } $query += $select $query += "DROP TABLE #logshippingstatus" $sql = $query -join ";`n" Write-Message -level Debug -Message $sql } process { foreach ($instance in $sqlinstance) { # Try connecting to the instance Write-Message -Message "Attempting to connect to $instance" -Level Verbose try { $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential -MinimumVersion 9 } catch { Stop-Function -Message "Failure" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } if ($server.EngineEdition -match "Express") { Write-Message -Level Warning -Message "$instance is Express Edition which does not support Log Shipping" continue } # Check the variables if ($Primary -and $Secondary) { Stop-Function -Message "Invalid parameter combination.
