Syslog-ng stopped logging.

12 October 2024, 03:37:03

The Files auth.log, user.log, syslog.log, messages.log, kernel.log, iptables.log, everything.log, errors.log, daemon.log and crond.log are no longer updating. I have no idea what's causing this problem.

The Rc.log file is being updated.
There are some error messages, but I think they are caused by optional dependencies.

I think this is just the recent change to the default config file which actually disables logging. You should have gotten this upgrade message in theory. Note, I don't know anything syslog-ng configuration so I don't know what you would actually do to renable the logging.

I think this is just the recent change to the default config file which actually disables logging.

That's hilarious on a few levels. Like why would the default be no logging and why would the message not at least give some explanation of what you'd need to do to enable logging?

@teyuss
After using syslog-ng for years I grew sick of the way it handles python and dependencies and also regular minor semantic changes to the configuration file format.
So I switched to metalog. After reading this thread I'm glad I did.

OK, reverting the configuration file back to version 4.6 fixed the problem...
Does anyone have any idea where to change the configuration file so that syslog start logging again?
