IT:AD:Event Log

## Summary

The Windows Event Viewer is the way to investigate event log entries raised by computers.

Considering its the primary way to track down errors, it's shocking how few developers actively investigate how to use it to its fullest potential.

Knowing how to focus in on errors raised by your application, as opposed to the rest of the system – affects how you design your logging service.

  • An event is any significant occurrence in the system or in a program that
    • requires users to be notified, or
    • an entry added to a log.
  • Logs are broken down into:
    • Application log: events logged by programs.
    • Security log: events such as valid and invalid access to secured objects.
    • System log: events logged by the OS system drivers, etc.
