I just released dgsmonX 0.2.2 (project page). This version should hopefully work again with DGS 1.0.15 (see previous post). If you encounter any issues, please let know by email.
Please note that to ensure responsible use of DGS resources (as requested in the DGS FAQ), I have implemented a minimum monitoring interval of 5 minutes (or 300 seconds). If you have configured a shorter interval, it will be automatically adjusted when you launch this version of dgsmonX for the first time. The minimum interval only applies to automatic checks, manual checks can still be triggered anytime you wish. Thank you for your understanding.
