What is Application Log?

A Microsoft Windows NT and Windows 2000 log that records events generated by applications running on the system.

The application log can be viewed and managed using Event Viewer and can contain three types of events:

  • Error event:
    Indicated by a red stop sign and signals a serious condition, such as a failed service


  • Warning event:
    Indicated by a yellow warning sign and signals a potentially serious condition, such as low disk space


  • Information event:
    Indicated by a blue information sign and signals a noteworthy event, such as a service successfully starting up
