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 SQL Server instance. .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. Windows Authentication will be used if SqlCredential is not specified. SQL Server does not accept Windows credentials being passed as credentials. To connect as a different Windows user, run PowerShell as that user. .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 errorlogpath path .PARAMETER Silent Use this switch to disable any kind of verbose messages .NOTES Author: Klaas Vandenberghe ( @powerdbaklaas ) Author: Simone Bizzotto ( @niphlod ) 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/Get-DbaMaintenanceSolutionLog .EXAMPLE Get-DbaMaintenanceSolutionLog -SqlInstance sqlserver2014a Gets the outcome of the IndexOptimize job on sql instance sqlserver2014a. .EXAMPLE Get-DbaMaintenanceSolutionLog -SqlInstance sqlserver2014a -SqlCredential $credential Gets the outcome of the IndexOptimize job on sqlserver2014a, using SQL Authentication. .EXAMPLE 'sqlserver2014a', 'sqlserver2020test' | Get-DbaMaintenanceSolutionLog Gets the outcome of the IndexOptimize job on sqlserver2014a and sqlserver2020test. .EXAMPLE 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 Get-DbaMaintenanceSolutionLog -SqlInstance sqlserver2014a -Since '2017-07-18' Gets the outcome of the IndexOptimize job on sqlserver2014a, starting from july 18, 2017. .EXAMPLE 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")] param ( [parameter(Mandatory = $true, ValueFromPipeline = $true)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [Alias("Credential")] [PSCredential][System.Management.Automation.CredentialAttribute()] $SqlCredential, [ValidateSet('IndexOptimize', 'DatabaseBackup', 'DatabaseIntegrityCheck')] [string[]]$LogType = 'IndexOptimize', [datetime]$Since, [string]$Path, [switch]$Silent ) begin { function process-block ($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+))?
