Description

Hi, I'm new to nginx, and I don't know where to post this, so excuse me if it's not the right place.

My problem is that I have a nginx instance running on a server, and it has produced the following files:

-rw-r----- 1 www-data adm 744 Jun 1 07:20 access.log
-rw-r----- 1 www-data adm 31162 Jun 1 05:49 access.log.1
-rw-r----- 1 www-data adm 3204 May 23 06:19 access.log.10.gz
-rw-r----- 1 www-data adm 3296 May 22 06:19 access.log.11.gz
-rw-r----- 1 www-data adm 9873 May 21 06:24 access.log.12.gz
-rw-r----- 1 www-data adm 10789 May 20 05:44 access.log.13.gz
-rw-r----- 1 www-data adm 23381 May 19 06:15 access.log.14.gz
-rw-r----- 1 www-data adm 2460 May 31 06:24 access.log.2.gz
-rw-r----- 1 www-data adm 10966 May 30 06:18 access.log.3.gz
-rw-r----- 1 www-data adm 8335 May 29 06:17 access.log.4.gz
-rw-r----- 1 www-data adm 19000 May 28 05:55 access.log.5.gz
-rw-r----- 1 www-data adm 3254 May 27 05:59 access.log.6.gz
-rw-r----- 1 www-data adm 8284 May 26 06:21 access.log.7.gz
-rw-r----- 1 www-data adm 8185 May 25 05:48 access.log.8.gz
-rw-r----- 1 www-data adm 13997 May 24 05:46 access.log.9.gz
-rw-r----- 1 www-data adm 0 Jun 1 06:25 error.log
-rw-r----- 1 www-data adm 503 May 31 14:47 error.log.1
-rw-r----- 1 www-data adm 375 May 16 04:30 error.log.10.gz
-rw-r----- 1 www-data adm 393 May 15 05:48 error.log.11.gz
-rw-r----- 1 www-data adm 303 May 14 05:58 error.log.12.gz

And, I'm trying to find some information about how those files are created in nginx, but I can't find anything on the nginx documentation (I've been searching for "nginx log rotation"). The closest I could find is this page: https://docs.nginx.com/nginx/admin-guide/monitoring/logging,
but it does not explain anything about log rotation.
I also downloaded the nginx free book (Complete-NGINX-Cookbook-2019.pdf), but again nothing about log rotation.

I just want to know more about log rotation in nginx, so that I can eventually try to organize them better (for instance, 1 log per day). Right now, I don't even know whether nginx changes the access log file based on the day, the size of the log, or another criterion.

For now I will simply open the files one by one and make an educated guess for myself, but I'm suggesting that the nginx documentation should provide a section about log rotation.

Cheers.

Log rotation is something provided by the OS, by programs like newsyslog or logrotate. Refer to your OS documentation to find out which one is used and how to configure it. Features provided by nginx to simplify log rotation are documented here.
