Reading Event Logs With VB Net?
Nov 19, 2009I'm working on a program to read event log entries from several remote servers...its basically to automate some daily checks we doMy code works but is very slow as the event logs can have up to 60,000 entries in them.I only need to check the logs from the specified date but when i run this it appears to check from the oldest entry to the newest. does anyone know how to reverse the order it looks in? or to save the index it checked from yesterday to a file and only check newer entries next time it's run (obviously i know how to save a number to a file and read it back.. i just mean in terms of the eventlog API stuff!!!)

View 2 RepliesAsp.net - Use VB To Query Remote Server Event Logs?
Aug 27, 2009I am working on creating a web app that will query event logs on internal servers for events using a specific ID. Since most of the servers are running Windows Server 2003, I cannot use the preferred System.Diagnostics.Eventing.Reader method that I was hoping to use.
I've seen the mention of using WMI, but would like to avoid this if possible. I have dabbled with the System.Diagnostics class but cannot seem to get it working when running on a server. It is able, when testing locally, to query my event log, but displays nothing when put on the final server. There is no error that is displayed after the program is ran.

Reading Event Log Using .NET?
Sep 8, 2009I've created an Event Log Source for my application name during the installation process (the end-users are not local admins) and the app writes any error messages to the Application event log.I now want to retrieve the error from the Application log and display them in a grid in my app.
The issue is that it takes more than 30 seconds to retrieve all of the entries,regardless of any filtering I perform in my WMI query. My query is:
"SELECT * FROM Win32_NTLogEvent Where Logfile = 'Application' And Sourcename = 'myApp' And TimeGenerated > '" + DateTime.Now.AddDays(-14).ToString("yyyyMMdd") + "'"
Initially I only filtered on the SourceName but it took 30+ seconds to retrieve about 100 records from 40,000 in the Application log. I added the TimeGenerated filter thinking it would reduce the query time but it was the same.
I tried using the ReturnImmediately enumerationoption property, which does return quickly, but when iterating through the collection it takes over 30 seconds to display the relevant entries.The benchmark I am working against is the speed at which the Windows Event Viewer opens the Application Log and applies a filter on the SourceName. This takes at most 5 seconds to redisplay the filtered list. However, I note that working on Vista, when I open Event Viewer, UAC prompts for admin elevation whereas my code will be reading from the Application log using standard user rights.

Reading The Message Of The Event Log Using System.Management Class?
Nov 2, 2011I am able to query/read the "Application" event log using System.Management classes in VB.net 2005 (win xp)But I have problem reading the "Message" / "description" of my custom event log.I am getting a System.NullReferenceException{"Object reference not set to an instance of an object."} while reading the "Message" / "Description of the event log while it is reading the others properties.Also when I use System.Diagnostics.EventLog and read all the Events on by one I am able to read the message/description of my custom event log. Why is that the System.Management classes can't read the my custom event log messages while the System.Diagnostics.EventLog classes can read them.The reason I want to use System.Management classes is bcoz I can query my custom event log where as with System.Diagnostics.EventLog classes I have to read the whole event log.

Returning Events Logs Using WMI - ObjectQuery
Apr 15, 2010I am working on a Visual Basic application that is returning Event Logs using WMI. I only want the latest 5 application, error events, but as I have the code now I get everything and then need to loop through and grab the first 5.
Dim wqlEventLogAs ObjectQuery =New ObjectQuery("SELECT * FROM Win32_NTLogEvent WHERE Logfile = 'Application' AND Type='Error'")
Dim objEventLogAs ManagementObjectSearcher =New ManagementObjectSearcher(myManagementScope, wqlEventLog)
ForEach objMgmtAs ManagementObjectIn objEventLog.Get
Next
I have tried a number of ways to add "Top(5)" to the query but each time I get "Invalid Query".
