Using WMI, how can I harvest events in a backed up event log file? I know how to read the current event log, but don't know how to query one that has been backed up and cleared.

Thanks.

Well, I guess I wasn't clear about how I wanted to access the archived log. I know I can view the archived events with the event viewer, but I need to do it using a WMI script.

Then you need to archive the events as comma delimited values (CSV).  You can then use any application to access those events - it's just a text file.

Here is the code I use to clear the current Application event log, saving these events to an event file.

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate,(Backup)}!\\" & _
strComputer & "\root\cimv2")
Set colLogFiles = objWMIService.ExecQuery _
("Select * from Win32_NTEventLogFile where LogFileName='Application'")
For Each objLogfile in colLogFiles
errBackupLog = objLogFile.BackupEventLog("c:\scripts\application.evt")
If errBackupLog <> 0 Then
Wscript.Echo "The Application event log could not be backed up."
Else
objLogFile.ClearEventLog()
End If
Next


What I am looking for is WMI code which would then let me read from this file -- code similar to the code that follows, but point it to the file I created above:

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colLoggedEvents = objWMIService.ExecQuery _
("Select * from Win32_NTLogEvent Where Logfile = 'Application'")
For Each objEvent in colLoggedEvents
Wscript.Echo "Category: " & objEvent.Category
Wscript.Echo "Computer Name: " & objEvent.ComputerName
Wscript.Echo "Event Code: " & objEvent.EventCode
Wscript.Echo "Message: " & objEvent.Message
Wscript.Echo "Record Number: " & objEvent.RecordNumber
Wscript.Echo "Source Name: " & objEvent.SourceName
Wscript.Echo "Time Written: " & objEvent.TimeWritten
Wscript.Echo "Event Type: " & objEvent.Type
Wscript.Echo "User: " & objEvent.User
Next

I have tried modifying the "select" statement above as follows, but his does not work:

("Select * from Win32_NTLogEvent Where Logfile = 'Application' and NTEventlogFile = 'C:\GWiens\Code\WinScripts\EventLog\application.evt'")

I'm not a WMI scripter.  But I think if you were saving / exporting the data as CSV, you could then use your script to access it.

My research shows that apparently there is not currently a way to read archived binary event files without additional enhancements such as proprietary extensions, etc.
