Windows 7 / Getting Started


To publish an event, the event must be registered using the ETW API. An XML manifest then defines how the event is published. Windows events can be published to either a channel or an ETW session.

A channel is a named stream of events. Channels are used to transport events from an event publisher to an event log file so that an event consumer can get the event. Figure below shows the structure of the channels and event logs in Windows Vista and later versions. Windows Vista and later versions include the following types of channels:

Event channel/event log structure
  • System System channels include the System, Application, and Security event log channels. These channels are created when Windows is installed on the computer.
  • Serviced Serviced channels include the following:
    • Admin Events in this channel primarily target administrators, support technicians, and users. Admin events generally indicate problems that have well-defined solutions that you can act on.
    • Operational Events in this channel are used for analyzing and diagnosing a problem with the computer. Operational events can be used to trigger tasks or tools for troubleshooting problems.
  • Direct Direct channels include the following:
    • Analytic Events in this channel describe problems that cannot be resolved by user intervention. Analytic events are published in high volume and can be queried but cannot be subscribed to. Analytic channels are disabled by default.
    • Debug Events in this channel are used by developers or support technicians for debugging system and application issues. Debug channels are disabled by default.

Note Analytic and Debug channel event information should first be converted to the standard Event Log (.evtx) file format to make it easier to read in Event Viewer.

By default, an event log file is attached to each channel except the analytic and debug channels. The event logs for those channels are disabled by default and are hidden from view in Event Viewer. To make Analytic and Debug event logs visible in Event Viewer, select Show Analytic And Debug Logs from the View method. Once these logs are displayed, you can selectively enable them by right-clicking on them and selecting Enable Log.
