Honestly I just wrote a small set of functions to log everything to Google Analytics via its measurement protocol[0]. I know I said I didn't use it client-side, but the dashboard is still top-notch for exploring analytics data and there's a ton of processing it does for free - IP to location is one. I also stream all logs into text files so I can process them later too.
