JSON formatter?

[JKoty]

Is it possible to set JsonFormatter and have all log records in JSON?

[miranovy]

You can set formatter in config.neon:

monolog:
	handlers:
		local:
			factory: Monolog\Handler\RotatingFileHandler(%appDir%/../log/my.log, 7)
			setup:
				- setFormatter(Monolog\Formatter\JsonFormatter())
