I am playing around with journalctl and getting used to the whole systemd setup, but having a hard time defining what it is actually doing...this site (https://www.loggly.com/ultimate-guide/using-journalctl/) says that journalctl is displaying messages from the journal but I can't search and find an answer to what the journal actually is. what is the journal?and...does journalctl eliminate the need to keep separate logs for everything?If I was to write a daemon, how can I make sure that it writes messages into the journal without then also writing them to a logfile for the daemon...is this possible? (I ask this because I seem to have an application statsd that does just this... there is no logfile but I can pull up its journal with journalctl -u statsd.service)
does journalctl eliminate the need for most logging?
