How to colorize your NGINX log files with CCZE
If your are into devops or someone who take care backend of NGINX, you will notice there is limited tools to read / transform NGINX access or error log files into colorize forms 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 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
