Nginx struct log Configuration

• To get the nginx logs in json format we have to modify the nginx.conf file in /etc/nginx directory.

• Modify the Logging Settings section in the nginx.conf file by adding the below lines:

	##
	# Logging Settings
	##
	log_format  json  '{'
                    '"remote_addr": "$remote_addr",'
                    '"remote_user": "$remote_user",'
                    '"timestamp": "$msec",'
                    '"request": "$request",'
                    '"status": "$status",'
                    '"request_time": "$request_time",'
                    '"body_bytes_sent": "$body_bytes_sent",'
                    '"http_referer": "$http_referer",'
                    '"http_user_agent": "$http_user_agent",'
                    '"http_x_forwarded_for": "$http_x_forwarded_for",'
                    '"upstream_response_time": "$upstream_response_time"'
                    '}';
	access_log /var/log/nginx/access.log json;
	error_log /var/log/nginx/error.log;

• Modify the line: access_log /var/log/nginx/access.log; to access_log /var/log/nginx/access.log json;

• To test nginx config file

nginx -t

• It shows like:

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok

nginx: configuration file /etc/nginx/nginx.conf test is successful

• Restart the nginx by using command:

/etc/init.d/nginx restart
