Utility script converting Apache/Tomcat log files to CSV format files

accesslog2csv

Utility script converting Nginx log files to CSV format files

Log format should be:
   log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                     '$status $body_bytes_sent "$http_referer" '
                     '"$http_user_agent" "$http_x_forwarded_for" '
                     '$request_time $upstream_response_time';

How to run

$ perl accesslog2csv.pl access_log_file > csv_output_file.csv

Or, you can redirect STDIN like the following examples:

$ perl accesslog2csv.pl < access_log_file > csv_output_file.csv

$ cat access_log_file | perl accesslog2csv.pl > csv_output_file.csv

Also, you can check invalid log lines by redirecting STDERR, too:

$ perl accesslog2csv.pl < access_log_file > csv_output_file.csv 2> invalid_log_lines.txt

Hope it helps somewhere! :-)
