syslog-ng and nginx logs to mysql

Solution 1:

I can help you to write nginx access log to postgres. Lets go Nginx log format

log_format logtodb '$time_iso8601;$http_host;$remote_addr;$http_x_forwarded_for;$request_method;$request;$status;$body_bytes_sent;$http_referer;$request_time;$upstream_http_x_cache;$uri;$upstream_addr;$host;$upstream_response_length;$upstream_status;$server_name;$newurl;$upstream_response_time';

access_log /var/log/nginx/access_logtodb.log logtodb; Let's go.

Configure syslog-ng

nano /etc/syslog-ng/syslog.ng
