Ensure that the systemd-journald service is enabled to allow capturing of logging events. If the systemd-journald service is not enabled to start on boot, the system will not capture logging events.
Solution
By default the systemd-journald service does not have an [Install] section and thus cannot be enabled / disabled. It is meant to be referenced as Requires or Wants by other unit files. As such, if the status of systemd-journald is not static investigate why.
