Logging configuration to send monolog logs to PHP error log

config.yml

# By default, Symfony logs will not appear by default in the logs on the DeltaBlue.Cloud platform.
# When using Monolog, you can add a handler with type set to `error_log`. 
# This will send all logs to the PHP error logs, and will let the platform indext it to show them.

monolog:
   handlers:
       main:
           type:  error_log
           level: debug

# This is just an example for a Symfony project using Monolog.
# More info can be found under Monolog > Handlers "ErrorLogHandler"
