How to generate dynamic log file names in rsyslog?

How to configure Rsyslog to use different ports?

How does Rsyslog work in Red Hat Enterprise Linux 7?

Standardized system logging is implemented in Red Hat Enterprise Linux 7 by the rsyslog service. System programs can send syslog messages to the local rsyslogd service, which will then redirect those messages to files in /var/log, remote log servers, or other databases based on the settings in its configuration file, /etc/rsyslog.conf.

How to control what logs appear in syslog?

You can deduce from this that some messages will appear in multiple log files, which is something we want to keep an eye on and control. For example, with the above settings, an incoming message with status mail.info will appear in three (3) log files: syslog, mail.log and mail.info.

How can I prevent Cron from filling up my syslog?

Otherwise you’ll still end up with the default behavior of cron logging to syslog, plus cron logging to cronlog (but not exclusively). And voila!

Is the rsyslog.conf file on the same host?

And a second identical VM on the same host (which didn’t go through quite the same circle of repeatedly disabling ntp, having the date changed and rebooted multiple times) with the same rsyslog.conf file logs just fine.

Where do I find the default rules for rsyslog?

You have to make sure that your new rules are evaluated before the one that logs to /var/log/syslog. so the default rules are loaded from /etc/rsyslog.d/50-default.conf, the one for /var/log/syslog included.

Why is systemd-rsyslog not logging in Linux?

That unit also creates /dev/log and triggers the start of systemd-journald.service. But if for some reason, that directive is missing or there is a non-fatal error in the rsyslogd configuration somewhere, it will use the default /dev/log and recreate that socket so that it can listen.

Are there separate logs for server and host?

That’s it, I can now see that there are separate logs created in /logs for my home office systems: becky, s7 and server are the hostnames. We were unable to load Disqus Recommendations.

Can a Raspberry Pi be a Rsyslog log collector?

I’m converting one of my Raspberry Pi systems, becky, into an RSyslog-based log collector, and while there’s not enough knowledge for a complete tutorial yet, I think I’ll start making short notes here in case someone comes looking for them.
