System Logs Format (rsyslog)

arrmo

No worries, understand the caveats, legal-ize, etc. ... LOL.

Thanks! I may go this way - then of course need to see if I can tweak the output format (i.e. need to modify the syslogd options a bit, to output the needed format).

Thanks again.

arrmo

OK, shifted to v2.5, seem to have the new and improved version of syslogd ... :-). Meaning, the -O format option exists. Perfect!

Now, how to modify the execution script to have this added to the command? I just need to find that.

arrmo

Checked the output, working great now - thanks for all the help!

Need to figure out the next step - would be nice to have this as a (GUI) option ... it's pretty simple. Just need to figure out how / where to suggest it.

Thanks again.

i still see syslogd on my 2.5.0
you can place additional configuration files in /var/etc/syslog.d
best place to ask for new features is https://redmine.pfsense.org/

Yup or pull-requests directly in github: https://github.com/pfsense

I made an issue for it here: https://redmine.pfsense.org/issues/9808

Should be simple enough to code, I'll get to it before long, assuming someone doesn't send in a PR first.

arrmo

Thanks! I was going to do that - just hadn't had a chance to yet.

yes ... it was easy to add the gui fuction

the problem is that if i set rfc5424
remote syslog still work

this are just example
on my rsyslog server, there is only the hostname instead of the ip, it is able to filter the incoming log

but from the gui i'm unable to see any log (i see only rfc3164) , i think that log filters also need to be adjusted based on rfc selected. and ... well ... that it's not easy for me

Finally had time to pivot back to this one. I pushed a fix that seems to do a decent job of parsing dynamically, even when the logs contain a mix of entries in different formats.

It should show up in snapshots soon.

@jimp Awesome, thanks! Will give it a try once it's in a snapshot. Much appreciated!

@jimp Seems to be working - thanks so much! Will keep an eye on it, let you know if I come across any issues. Much appreciated!
