How do I modify the nxlog config file to send all IIS logs in JSON format?

## This is a sample configuration file. See the nxlog reference manual about the
## configuration options. It should be installed locally and is also available
## online at

## Please set the ROOT to the folder your nxlog was installed into,
## otherwise it will not start.

#define ROOT C:\Program Files\nxlog
define ROOT C:\Program Files (x86)\nxlog
define CERTDIR %ROOT%\cert
# Include your Loggly Customer Token here
define CUSTOMER_TOKEN 111111111-111111-11111-1111-1111111111

Moduledir %ROOT%\modules
CacheDir %ROOT%\data
Pidfile %ROOT%\data\
SpoolDir %ROOT%\data
LogFile %ROOT%\data\nxlog.log
