Creating Windows Event Log Events

Creating Windows Event Log Events

We use VMware vCenter Configuration Manager at our site to monitor our Windows servers for signs of future problems by searching the Windows Event Logs for a predefined list of events. Every once in a while (especially after a while without alerts) you want to test and make sure that everything is indeed being monitored properly. To do this I needed to inject an event into the Event Log and see if we received an alert in VCM. The question was this: how do I impersonate an existing service? The built in eventcreate.exe will not let you add events for a source that already exists, which is exactly what I want to do… Ah, I love it when people have already coded an application to do something that I need to do and save me from having to write it myself.

Eventcreate2.exe has one flaw, you cannot specify a remote machine; as opposed to the built in eventcreate.exe which does let you specify remote machines. Other than that it is awesome. Using a command like the below I was able to successfully inject events impersonating an existing service and verify that our alerting was indeed working as advertised.
