Hi friends. Hope everyone is doing well.

I got this issue today i really feel dumb about it.

i double checked the location of the file with :

sudo -u apache php /var/www/html/nextcloud/occ log:file

Log backend file: enabled
Log file: nextcloud.log
Rotate at: 100 MB

i found the log file

find / -name nextcloud.log | xargs ls -lah

-rw-rw-rw-. 1 apache apache 0 May 29 10:58 /var/www/html/nextcloud/data/nextcloud.log

at some point the conf worked but after adding the timezone it failed.
So i removed this options and tried many other possibilities

the official documentation config :

"log_type" => "file",
"logfile" => "nextcloud.log",
"loglevel" => 3,
"logdateformat" => "F d, Y H:i:s",

this sub workaround config :

Nextcloud Logfile Not in /var/log/nextcloud.log

My config.php: <?php $CONFIG = array ( 'instanceid' => '*', 'passwordsalt' => '*', 'secret' => '*', 'trusted_domains' => array ( 0 => '*', 1 => '192.168.2.2', 2 => '192.168.178.30', ), 'datadirectory' => '/home/*/nextcloud/nextcloud_data', 'overwrite.cli.url' => 'https://*/nextcloud', 'dbtype' => 'mysql', 'version' => '9.1.0.16', 'dbname' => 'nextcloud', 'dbhost' => 'localhost', 'dbport' => '', 'dbtableprefix' => 'oc_', 'dbuser' => 'nextcloud', 'dbpa…

nothing works anymore but it worked at some point that’s why i’m puzzled.

am i missing an obvious point here ?

SElinux is disabled.
I cannot find the log which can tell me why logging doesn’t work.

Can some nexctloud wizard give me a hint here cause i feel so dumb about this.

Thank you very much and have a good day.

i changed the config with this block :

  'log_type' => 'file',
  'logfile' => 'nextcloud.log',
  'loglevel' => 2,
  'logdateformat' => 'F d, Y H:i:s',
  'log.condition' =>
  array (
    'apps' =>
    array (
      0 => 'admin_audit',
    ),
  ),

i removed all logfiles with :

find / -name nextcloud.log | xargs rm

and immediately i can see all those logfile :

-rw-r-----. 1 apache apache 552 May 29 15:04 /srv/cloudata/nextcloud.log
-rw-r--r--. 1 apache apache   0 May 29 15:04 /var/www/html/nextcloud/nextcloud.log
-rw-r--r--. 1 apache apache   0 May 29 15:04 /var/www/html/nextcloud/ocs/nextcloud.log

i’m really puzzled how it works. it touch different files in different locations (i don’t get why) and those files apparently are read only or cannot be written by nextcloud.
