I use uwsgi with the parameter --daemonize /logs/uwsgi.log

This file is however becoming large and I would like to split it into smaller pieces. One per day would be pre

Based on roberto's answer here is the configuration that will rotate logs. It will keep up to 14 log files. Daily rotation at 3:15.

[uwsgi]
set-placeholder = log_dir=/var/log
set-placeholder = log_prefix=myservice-
set-placeholder = log_num=14
pidfile = /var/run/uwsgi-myservice.pid
logto = %(log_dir)/%(log_prefix)@(exec://date +%%Y-%%m-%%d).log
log-reopen = true
unique-cron = 15 3 -1 -1 -1 { sleep 66 && kill -HUP $(cat %(pidfile)) && ls -tp %(log_dir)/%(log_prefix)* | grep -v '/$' | tail -n +%(log_num)  | xargs -d '\n' -r rm --; } &

The sleep is needed because after reload uwsgi will execute cronjob again because it would match current time. So we need a sleep for more than 60 seconds before reloading. It also reloads configuration file on every rotation, such behavior might be not desired.

Why one would need such a hack? Well, in my case I don't have access to properly configure logging in the system, but I have permission to change uwsgi config.
