Thanks to the clarification. I did look in the syslog.conf file and
found the files to look at. I was understanding that ‘debug’, ‘error’,
‘info’, etc. were types of log messages, not levels, and when I found
out they were levels, I didn’t know what the hierarchy was.
I will try out syslog-ng. Thanks for the help

I’m not versed on the syslog filtering options. I would like to see
multiple types of logs, but hopefully have them in their own
files so I don’t have to parse through a single file. But even if I
wanted them all to log to a single file (eg. the syslog), the last one
wins, so how can I get the debug, error, and info logs to all log to
You are confused. First of all, the values ‘debug’, ‘error’, ‘info’ are
levels: what you get in the log is everything of the named level or
above. So, if you choose ‘debug’ (the lowest level) you’ll
automatically get all of the ‘error’ and ‘info’ stuff as well.
Conversely, if you choose ‘error’ (the highest of the levels listed),
you’ll not get the lower level ‘debug’ or ‘info’ messages.
You should also look at /etc/syslog.conf which controls where the system
writes the logged data to. Typically you should find everything goes to
at least one log file – /var/log/all.log or /var/log/message or various
other possibilities depending on OS and distro. You can use syslog.conf
to filter messages by log level or various other criteria. You can even
arrange for data to be logged to a separate server on your network.
