Matomo Version: 3.9.1
PHP Version: tested with 7.0.33 and 7.3.3
Middleware: Apache 2.4
OS : Debian
I followed the instructions of https://matomo.org/faq/troubleshooting/faq_115/ to enable log in Matomo.
So I added:
[log] log_writers = file log_level = DEBUG
in my config/config.ini.php
I checked if the Monolog Plugin was enabled and it was.
But no log file is created.
I try to add
logger_file_path = /var/www/html/tmp/logs/matomo.log
but same result.
I also try to log in database but nothing still visible in LogViewer plugin.
Could you please tell me if I miss something?
Thank you in advance.
It's only created when something is actually logged. We're actually not too big on logging and usually only logging when something goes wrong.

dispatch method around line 150. Maybe something appears then?
Thank you @tsteur for you answer.
I followed your instructions and I navigated on the UI but unfortunately without result

I am just setting up a new Matomo instance and no matomo.log file is created.
Maybe this is a regression from one of the recent logging changes
I can reproduce it when the
screen writer is not enabled. If the screen writer is enabled too, then it works.
Actually I can't reproduce it. I had a mistake in the config file. Tested various cases with and without instanceId etc.
Maybe only happens with some specific PHP version or so. The file that does it is
I doubt we can do much on our side here. If someone could debug this, that would be great. We may have a look if someone can provide access to a server and Matomo where this can be reproduced. Make otherwise sure the config section isn't defined twice etc.
For me manually applying https://patch-diff.githubusercontent.com/raw/matomo-org/matomo/pull/14296.patch does fix the issue (you can ignore the change in
(thanks to @diosmosis for the tip)
I still have this issue with Matomo v3.9.1. PHP version I am using is php 7.2 by red had software collections.
I am going to try to apply the patch manually.
The patch actually solves the problem. Should be applied in next Matomo version.
