Hello,
I would like to know if there is any open source tool for me to analyze memory usage / processing allocated by my production methods.
I would like to know what methods need attention and improvements, and thus decrease the resource usage by my applications.
My production environments are composed of php-5.6 or php-7 (depending on the application), nginx as a reverse proxy, Apache2 behind NGINX (for limitations in some applications), and Linux (Ubuntu / CentOS) as SO
But in this case, you need to measure peak access on these Web Servers , rrdtool , cacti + mrtg strong>, you will get the graphics of those hits.
Next you have the disk speed and amount of ram memory and the size and amount of access to the database.
When you have these graphs you will get an idea of the general context that is occurring on the Server as a whole, try to start from that point first.
Of course this was a suggestion, mine that I took care of for almost 10 years of hosting environments, I hope you can help, any questions I am available.
