Understanding Event Sources

Event Sources are scripts that produce events.

They are generally named @NameOfSource.ps1.

Events in PowerShell can be produced in two ways:

• .NET Objects can produce events.
• An event can be sent by PowerShell.

An event source script can return any object with events, and indicate which events to subscribe to either by addding a [Diagnostics.Tracing.EventSource(Name=’EventName’)] attribute or by adding a noteproperty called “EventName” to the return.

Event sources can be found a few places:

• In the current directory
• In any function whose name starts with @
• In the directory where Watch-Event is defined
• In the module root where Watch-Event is defined
• In an .Eventful [Hashtable] within a module manifest’s private data
• In a module that .Tags Eventful

You can see the event sources currently available with:
