Same concern here: if .err is sourced from stderr as stated in the PR description, this console appender targeting SYSTEM_OUT won’t influence .err formatting. Consider using target=\"SYSTEM_ERR\" (or aligning systemd routing) to ensure .err lines include the new timestamp.

Same as server: the description references stderr->.err, but the console appender is configured for SYSTEM_OUT. If .err is populated from stderr, the timestamped pattern won’t be reflected there unless the target is SYSTEM_ERR (or the unit routes stdout to .err).

I think we need to double check this, @dheeraj12347 . I looked in an env and the .out file already contains the date stamps for each line. The .err file doesn’t .

You’re right, Daan – .out already had timestamps while .err didn’t. I’ve now added a CONSOLE_ERR appender using SYSTEM_ERR with the same timestamped pattern, so stderr (and thus the .err files) will get timestamps as well.

The PR description says the .err logs are fed from console/stderr, but this Console appender targets SYSTEM_OUT. If systemd is capturing stderr into .err, changing the stdout pattern won’t affect .err. Consider switching the console target to SYSTEM_ERR (or update the systemd unit routing) so the timestamped console output actually lands in .err.
