functions/Get-DbaMaintenanceSolutionLog.ps1
function Get-DbaMaintenanceSolutionLog { <# .SYNOPSIS Reads the log files generated by the IndexOptimize Agent Job from Ola Hallengren's MaintenanceSolution. .DESCRIPTION Ola wrote a .sql script to get the content from the commandLog table. However, if LogToTable='N', there will be no logging in that table. This function reads the text files that are written in the SQL Instance's Log directory. .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 LogType Accepts 'IndexOptimize', 'DatabaseBackup', 'DatabaseIntegrityCheck'. ATM only IndexOptimize parsing is available .PARAMETER Since Consider only files generated since this date .PARAMETER Path Where to search for log files. By default it's the SQL instance error log path path .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: Community, OlaHallengren Author: Klaas Vandenberghe (@powerdbaklaas) | Simone Bizzotto ( @niphlod ) Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT https://ola.hallengren.com .LINK https://dbatools.io/Get-DbaMaintenanceSolutionLog .EXAMPLE PS C:\> Get-DbaMaintenanceSolutionLog -SqlInstance sqlserver2014a Gets the outcome of the IndexOptimize job on sql instance sqlserver2014a. .EXAMPLE PS C:\> Get-DbaMaintenanceSolutionLog -SqlInstance sqlserver2014a -SqlCredential $credential Gets the outcome of the IndexOptimize job on sqlserver2014a, using SQL Authentication. .EXAMPLE PS C:\> 'sqlserver2014a', 'sqlserver2020test' | Get-DbaMaintenanceSolutionLog Gets the outcome of the IndexOptimize job on sqlserver2014a and sqlserver2020test. .EXAMPLE PS C:\> Get-DbaMaintenanceSolutionLog -SqlInstance sqlserver2014a -Path 'D:\logs\maintenancesolution\' Gets the outcome of the IndexOptimize job on sqlserver2014a, reading the log files in their custom location. .EXAMPLE PS C:\> Get-DbaMaintenanceSolutionLog -SqlInstance sqlserver2014a -Since '2017-07-18' Gets the outcome of the IndexOptimize job on sqlserver2014a, starting from july 18, 2017. .EXAMPLE PS C:\> Get-DbaMaintenanceSolutionLog -SqlInstance sqlserver2014a -LogType IndexOptimize Gets the outcome of the IndexOptimize job on sqlserver2014a, the other options are not yet available! sorry #> [CmdletBinding(DefaultParameterSetName = "Default")] [Diagnostics.CodeAnalysis.SuppressMessageAttribute("PSUseApprovedVerbs", "", Justification = "Internal functions are ignored")] param ( [parameter(Mandatory, ValueFromPipeline)] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [ValidateSet('IndexOptimize', 'DatabaseBackup', 'DatabaseIntegrityCheck')] [string[]]$LogType = 'IndexOptimize', [datetime]$Since, [string]$Path, [switch]$EnableException ) begin { function process-block ($block) { $fresh = @{ 'ObjectType' = $null 'IndexType' = $null 'ImageText' = $null 'NewLOB' = $null 'FileStream' = $null 'ColumnStore' = $null 'AllowPageLocks' = $null 'PageCount' = $null 'Fragmentation' = $null 'Error' = $null } foreach ($l in $block) { $splitted = $l -split ': ', 2 if (($splitted.Length -ne 2) -or ($splitted[0].length -gt 20)) { if ($null -eq $fresh['Error']) { $fresh['Error'] = New-Object System.Collections.ArrayList } $null = $fresh['Error'].Add($l) continue } $k = $splitted[0] $v = $splitted[1] if ($k -eq 'Date and Time') { # this is the end date, we already parsed the start date of the block if ($fresh.ContainsKey($k)) { continue } } $fresh[$k] = $v } if ($fresh.ContainsKey('Command')) { if ($fresh['Command'] -match '(SET LOCK_TIMEOUT (?<timeout>\d+); )?ALTER INDEX \[(?<index>[^\]]+)\] ON \[(?<database>[^\]]+)\]\.\[(?<schema>[^]]+)\]\.\[(?<table>[^\]]+)\] (?<action>[^\ ]+)( PARTITION = (?<partition>\d+))?
