Finally, you can specify an EventLogEntryType for the event being written to the event log. The type is indicated by an icon and text in the Type column in the Event Viewer for a log. This parameter indicates whether the event type is error, warning, information, success audit, or failure audit.
To write to an event log, you must have several pieces of information: Your message, the name of the log you to where you want to write (this is created if it does not already exist), and a string that represents the source of the event.Windows Logging Basics. Logs are records of events that happen in your computer, either by a person or by a running process. They help you track what happened and troubleshoot problems. The Windows event log contains logs from the operating system and applications such as SQL Server or Internet Information Services (IIS).If the maximum log file size entered is smaller than the Current Log File Size, a warning message appears advising that some of the oldest events will be deleted from the file. Logging Level Control You can specify which levels of events are recorded, for example, to record all events, select 3 - Information, or to record just the critical events, select 0 - Critical.
The EventLog type can be used to write entries to the system event log. After assigning the Source, you can call WriteEntry (or WriteEvent) to actually write messages to the system, which can then be found in the event log. And: This can be beneficial to debugging software remotely—you can tell users to look through the event log.
Double-click Event log: System log SDDL, type the SDDL string that you want for the log security, and then click OK. Use Group Policy to Set Your Application and System Log Security for a Domain, Site, or Organizational Unit in Active Directory.
To use Windows Event Viewer In Microsoft Windows, an event is any significant occurrence in the system or in software that requires users to be notified, or an entry added to a log. The Event Log Service records application, security, and system events in Event Viewer.
The Windows Event Logs. Since the first server operating system from Microsoft, the Windows system has used the Event Log program to record and view log entries from at least three sources: System, Security, and Applications.
This allows you to log errors or other events to the Event log from within a Catch block, without interrupting the page flow and relying on the global exception handler. Add backup code that logs the errors to a text file or sends out an e-mail in case the Event Log or Source does not exist.
That's why I've decided to write a post that will take you on a trip on how to work with Event Logs, something that is an internal part of Windows Administration. If you've never worked with Events and you're in IT you most likely should make an effort to find out what it is and how you can eat it.
You can write directly to an existing source in the Windows Event Log, but sifting through these logs can become tedious at best. To make it easier to find a specified log one of your scripts created, I believe you should first create a new source in the Windows Event Log.
Listing 3.10 shows an example of how to write information to the Windows event log. This code first checks to see if an event source called MyApp exists; if not, the code creates it. The code then sends information to the event log by calling the WriteEntry method of the EventLog object.
Using the common language runtime's EventLog component, you can easily connect to existing event logs on a local computer, and write entries to these logs. You can also read entries from existing logs and create your own custom event logs. This sample illustrates how to write to an event log.
How do I view the error messages registered in Event Log? Click Start, Run and type eventvwr.msc Select Application entry in the left pane In the right-pane, look for the Error entry denoted by a Red X.
Event Viewer is my usual stop to check event log when needed. It has everything I need to find the information I am looking for but still, sometimes I do feel the needs of having a better way to quickly check out the log file from a local and remote computer.
The Windows Event Viewer is a convenient way for any user to view the system logs and troubleshoot any potential problems. To make even better use of Event Viewer you can create your own custom entries in the event logs. Here we show you how to do it along with some useful scenarios and tips on usage.
So far, it is simple and easy to log into the machine and navigate to Events Log to view any unhandled exceptions. Now, If you take Azure App Service, which is a Platform as a service, you will not have the facility of logging into the server and connecting to the Event Log Viewer as shown above.
Figure 1: Event Log Showing Entry Generated by Test Project. If you were to open the event log entry from the system event log viewer, you would see that the demo project generated an entry like this: Figure 2: Event Properties from Event Log Entry.
