logging with context

i have had this blog post about moving from logs to metrics open for a while, since i know one of the weak points in our systems right now is some pretty basic stuff like logging and monitoring. and then jwz ran into a problem with logging errors from php-fpm and what it reminded me about is how logs need to carry enough context so you can pull the threads together from something like a single request.

i have not wrapped my head around the idea of just using metrics, because that sounds like rather a lot of data to be storing. maybe i’m just an on-prem brain in a cloud world.
