The best way to monitor any of the sites is to log into their account. Most sites like Pricegrabber or Google will contact you with issues. In our system, in the Program Options, you can enter in your email address so our system can email you if there is an issue building a feed or uploading. If the error persists, it will keep emailing you until it is fixed. The system is designed to run feeds hourly. Sometimes a product import may fail. When this happens, the system will try and re-import. If you have set a minimum import quantity in the Program Options, then it will not build any new feeds until the next time the Product Import is ran, typically the next day. It may send you emails letting you know this is happening.
