The challenge is to write a parser for an nginx log file in the format:
"Our nginx.conf has this format for log entries log_format custom '$remote_addr $server_name $remote_user [$time_local] ' '"$request" $status $body_bytes_sent ' '"$http_referer" "$http_user_agent"';
Please write a program that parses nginx log and outputs html grid with German ip addresses only. Please add sort and search functionality to this grid."
