As an Android developer, during spare time developed a Java/C server-side component and Android app system to allow real-time event subscriptions on web traffic to a variety of clients (mobile, desktop, web) without the need to read web log files (i.e. from RAM). Unlike Google Analytics, this provides direct visibility into all traffic and not just JavaScript visible content. The Android app, provides an interface for web admins to design custom subscriptions to web traffic events they might be interested in (eg. specific web requests, security probes, traffic patterns, web content popularity, illegal linking, etc.) and deliver this information on these events in-real time (via Android’s GCM service) to the user.
