4. Run the script as depicted below.

Usage

python monitor.py <memory_notation> <pid_file>

where memory_notation:

k = kilobytes

m = megabytes

g = gigabytes

otherwise = bytes

Example for self-saving PID in Java 8 or before

// this snippet was tested only on Linux
int savePid(String filepath) {
  int pid = Integer.parseInt(new File("/proc/self").getCanonicalFile().getName());
  File tmp = new File(filepath);
  tmp.write(pid);
  return pid;
}
