log all major logical branches within code (if/for)
if "request" span multiple machine in cloud infrastructure, include request ID in all so logs can be grouped
if possible make log level dynamically controlled, so grug can turn on/off when need debug issue (many!)
if possible make log level per user, so can debug specific user issue
The only one I'll add is: If your logs are usually read in a log aggregator like Splunk or Grafana instead of in a console or text file, log as JSON objects instead of lines of text. It makes searches easier.
