Tracking Request Times

This will find all (new) requests with an upstream response time > 0.5s.

docker logs --since=0s -f nginx | sed -e 's/^[^{]*//' | jq -R 'fromjson? | select((.upstream_response_time | split(" : ")[0] | tonumber) > 0.5) | {request: .request, upstream_response_time: .upstream_response_time}'

Profiling

pip install line_profiler

Time per Line in a Request-Context Function

with app.test_request_context():   
   %lprun -f listing listing()
