Managing Logging in Systemd

The initialization daemon systemd has become the de facto standard in modern Linux systems and is already used in many popular distributions: Debian, RHEL/CentOS, and Ubuntu (as of ver. 15.04). Compared to the traditional syslog, systemd offers an entirely different approach to logging.

In this case, there’s no need to configure log distribution, instead the applications can just write to stdout and stderr, and journal automatically saves these messages. This setup is possible with Upstart, but Upstart saves all logs to a separate file, whereas systemd saves them in a binary base, greatly simplifying systemization and searches.
