Measurement of memory usage
Measure how much memory a process occupies. Linux provides us with a very convenient method, The /proc directory provides us with all the information. In fact, tools such as top also use this to obtain the corresponding information.
/proc/meminfo Machine memory usage information
/proc/pid/maps pid is the process number, showing the virtual address occupied by the current process.
/proc/pid/statm Memory occupied by the process
