monitoring services

I must be missing something very basic here, but I cannot get hobbit to monitor a specific service on some Windows 2003 servers.

In bb-hosts I use the PAGE directive to split up Linux and Windows servers.

In hobbit-clients.cfg I want to check just the Windows servers for a service called fstats.exe:

PAGE=Windows

    PROC fstats.exe

But this just doesn't work.

I'm 100% sure that is the name of the service, and I already do something similar (albeit not on the same network) to monitor sqlservr.exe on some Windows servers but from another hobbit server.

Any ideas what I'm missing?

Thanks.
