Local logging works but records no useful events

[dmitrydonskih]

Hello, I have ViMbAdmin 3.4.1 running on PHP 8.2.14.
It works fine, logging is enabled, but I don't see most useful events in log. Actions like create/modify/delete domains/mailboxes/aliases/admins etc. are NOT logged. The only records in my log are:

2024-01-11T13:10:02+03:00 DEBUG (7) [10.10.21.11]: Logger instantiated
2024-01-11T13:10:02+03:00 NOTICE (5) [10.10.21.11]: Authentication failure for xxxx@doma.in

Settings in application.ini are as following:

ondemand_resources.logger.enabled = 1
ondemand_resources.logger.writers.stream.level = 7
#--
resources.doctrine2.logger             = 1
#--
ondemand_resources.logger.writers.stream.path    = "/var/log"
ondemand_resources.logger.writers.stream.owner   = nginx
ondemand_resources.logger.writers.stream.group   = nginx
ondemand_resources.logger.writers.stream.mode    = single
ondemand_resources.logger.writers.stream.logname = vimbadmin.log

No errors, no warnings about PHP or execution.
Am I missing something?

And, by the way: is logging to SYSLOG supported? If yes, how can I enable it?

Thanks.
