If your are into devops or someone who take care backend of NGINX, you will notice there is limit of tools to read / transform NGINX access or error log files into colorize which is helpful and readable, compare to Httpd / Apache which have tonnes of script and tools to colorize your logs.
The last time I configuring NGINX was 4 years ago and yesterday I setup webserver for my client using NGINX instead of Httpd / Apache, after 7 minutes port 80 was open to public, I notice slowness on my client VPS machine, so I assume maybe some massive bots are scanning this webserver for some reason.
I open NGINX log with my favourite less- R command line and I feel awful and ackward. Do you know why? Because I been involve with lot of programming framework and tool that offer me ANSI colorize log.
If you are just like me, then I suggest you to install ccze! Here some currrent info from Fedora repository
