FastAPI and Uvicorn Logging #python #fastapi #uvicorn #logging

FastAPI and Uvicorn Logging

When running FastAPI app, all the logs in console are from Uvicorn and they do not have timestamp and other useful information. As Uvicorn applies python logging module, we can override Uvicorn logging formatter by applying a new logging configuration.

Meanwhile, it's able to unify the your endpoints logging with the Uvicorn logging by configuring all of them in the config file log_conf.yaml.

Before overriding:

uvicorn main:app --reload

vimgrep cheatsheet

vimgrep

  • Vimcasts on vimgrep

  • Uses native vim regexes (which are slightly different from the regexes used by grep, ack, ag, etc) so the patterns are the same as with vim's within-file search patterns.

You can do a normal within-file search first, then re-use the same pattern to

Different Linux utility commands (e.g. top, ps, strace, lsof, netstat, ifconfig, iftop, iptraf, tcpdump, wireshark)

Start up a container (whichever Linux flavour takes your fancy):

docker run -it ubuntu /bin/bash
docker run -it centos /bin/bash
  • top: check what CPU and Memory running processes are utilising
  • ps: see what processes are running
  • strace: monitor interactions between processes

Enable persistent storage for the systemd journal log

Enable persistent storage for the systemd journal log

Overview

The assumed default setting in /etc/systemd/journald.conf is Storage=auto which implies that systemd journaling will only persist the journal if the expected storage location is available. Otherwise, the journal data is stored in memory and lost between reboots. On Ubuntu 16.04, /var/log/journal does not exist by default. Create it to keep and query events from previous boots.

Considerations:

  • Syslog still provides the persistant log records for Ubuntu 16.04, so enabling persistant systemd journal logging does cause a level of duplicaiton.
  • There are sane defaults:
