AspEventlog

You can log additional information to the site logs using Response.AppendToLog, however, sometimes it is important to see events reported to a more central log of Windows NT itself - the Application eventlog (like the Application_OnStart event in global.asa).

You can use Event Viewer immediately to filter for events, without having to go to the log files and processing them.

The AspEventlog component can be used from any OLE Automation enviroment, including but not limited to ASP (though the name would imply that). It registers itself with the eventlog during the standard OLE registration process.

The component's interface is intended to be simple, but powerful if you want to have events reported to the Application eventlog of the local server (works with a standard installation, aka server runs under IUSR_machinename account).

All four different event types (success, error, warning and information) can be logged, together with a single string of information (you are free to include anything in this string, like IP, user agent, etc).
