Note

1. The default logger setup (zapjournal.New() and zapjournal.NewDebug()) produce a named logger with the executable file name get from os.Executable(). This behavior is different from zap.

2. The key passed to zap will be convert to UPPERCASE. And all in key will be replaced with _. As journald seems refuse to record such fields.

3. journalctl will not show any custom fields by default. And it not support any format customization option to display custom fields. But it has an option to output log as json which can be pass to jq, Then that be formatted to a human readable output.

   Check journalfmt as well.
