Is it possible to store journal logs matching specific filters to different journal files in addition to the main journal using some journald configurations?
For eg., All journal logs of severity critical and above should be stored in /var/log/critical/critial.journal in addition to the main journal. Currently I am achieving this via combination of systemd-journal-remote and journalctl as below ExecStart=/lib/systemd/systemd-journal-remote --output=/var/log/critical/critical.journal --getter="journalctl -f PRIORITY=3 -o export" In this approach, I have the following disadvantages 1) For each filter output combination, I need to create additional service 2) Somethings we miss few logs, couldnt root cause it yet. 3) Also I not sure whether this would be a better compared to the systemd-journald directly storing them in different journal files. Hence, I prefer a systemd-journald configuration like following TargetFilter1="PRIORITY=2" TargetDestination1="/var/log/critical.journal" TargetFilter2="_UNIT=CPROCESSOR" TargetDestination2="/var/log/cprocessor.journal" which will store those logs matching the filters to the corresponding destination.
