If this capability were developed, would it be included with Foreman or be pushed into a plugin (can a Rails engine reconfigure global logging?)?

I have a syslog implementation working on our dev Foreman using the syslogger gem and it seems to work ok. I see #10487 is attempting to address this as well, so not sure if I should pursue it. My change is pretty minimal, just two new settings syslog and syslog_facility.

Syslogger gem looks good in term of dependencies but seems quite basic. To implement #10487 you mention I think another gem called logging would be better fit. It also supports syslog (as one of appender). So I suppose if you used logging instead, I think it would be welcome and merged into core.

Actually, I missed that the #10487 is already ready for testing, so I think you can just wait a bit longer, until it gets in. It should allow you to customize log outputs to use syslog.

#10487's merged and should be in nightlies soon. You can reconfigure /etc/foreman/logging.yaml to enable syslog output, but I don't know that the output is in a particularly syslog-esque style. We could take improvements to the examples in logging.yaml perhaps for formatting and setting the facility.
