15 August,2008 by Tom Collins

Running the code below within the Powershell interface will list designated Errors Log messages instances (SQL SERVER 2005) listed in the "C:\InstancesPROD_2005.txt" document.
An example of the lists in that document is:


Currently the sql code will designated errors failed within the last 2 days. Configure to your requirements.

To run ,  copy and paste straight into a Powershell  cmdlet ,which is a series of commands, usually more than one line, stored in a text file with a .ps1 extension. 


----------------------------------CODE START-----------------------------------------

foreach ($svr in get-content "C:\InstancesPROD_2005.txt"){
    $dt = new-object "System.Data.DataTable"
    $cn = new-object System.Data.SqlClient.SqlConnection "server=$svr;database=msdb;Integrated Security=sspi"
    $sql = $cn.CreateCommand()
    $sql.CommandText = "

DECLARE @sqlStatement1 VARCHAR(200)
SET @sqlStatement1 = 'master.dbo.xp_readerrorlog'
        CREATE TABLE #Errors (LogDate DATETIME,ProcessInfo NVARCHAR(50),vchMessage varchar(2000))
INSERT #Errors EXEC @sqlStatement1
SELECT LogDate, RTRIM(LTRIM(vchMessage)) FROM #Errors WHERE 
([vchMessage] like '%error%'
   or  [vchMessage] like '%fail%'
