I need the ability to create hourly reports for a few devices and all their sensors. I see where you can generate a report every hour, but it only has the option to report on a full previous day's worth of data. I saw in one of your case studies (http://www.paessler.com/company/casestudies/pferd) where it appeared someone was doing this.
If I have to edit a config file I am fine with that. We use Sitescope right now that has this ability and would need to be able to do this with PRTG.
