XP_READERRORLOG or SQL SERVER ERRORLOG


We can search error log with the below mentioned extended stored procedure the main thing we need to remember here is ""(double quotes) and the date format should be YYYY-MM-DD


The below powershell query will fetch the SQL Server error log information. It will read all error log files. 
cls
Get-ChildItem -Path "D:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Log" -File -Name -Include ERRORLOG*|
ForEach-Object {
$IndFile = $_ 
$filters = @("offline","Database1","Database2","Database3")
$inputFile = "D:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Log\$IndFile"
Get-Content $inputFile | Select-String -pattern $filters -AllMatches
}
