I would like to know not only the number of impressions of an ad in a zone by hour, but also the device that received the impression. I have been observing the database, and it appears that data_bkt_m keeps a running count by ad_id and zone_id, then updates data_intermediate_ad hourly. The webpage requests ajs.php with arguments for zone id and call back values. I assume somewhere in this request is where data_bkt_m is updated. I'd like to pass a third argument that represents the fingerprint of the device making the request. If someone could point me towards the documentation that explains how to extend the application to acheive this, it would be most appreciated.
