How to get system statistics in PHP

Question

I am launching a beta version of a web application and I want to record system resource information. system monitors eat too many resources and do much more than I need. What I want to do is get key statistics and register them every time a user logs in.

these are the statistics that interests me:

• number of users - I already did it
• system 5 min and 15 min load - php get average load

On a Linux / Unix-based system, you can read files in / proc /, such as / proc / meminfo and / proc / net / dev (although the netstat -i command output is much easier to parse on a network).
