Is there a good guide to getting started using logfiles as the basis for analytics? Best practices on using client vs server-side signals (and if both, not double-counting), etc. I'm interested in learning more about it, but a google search doesn't turn up anything relevant. Snowplow seems to be using a setup like this, but not sure how they'd fit in with what the author was discussing.

I'm using Django, but I imagine this kind of system would be mostly platform-agnostic.
