Hello, I would like to know if it is possible for me to do a system in vuejs or directly in php that will take up how much RAM I am using in total with all programs.

With PHP on Linux you can use /proc/meminfo and return the information in memory as an array: 

<?php
function getSystemMemInfo(){       
    $data = explode("\n", file_get_contents("/proc/meminfo"));
    $meminfo = array();
    foreach($data as $line){
        list($key, $val) = explode(":", $line);
        $meminfo[$key] = trim($val);
    }
    return $meminfo;
}

foreach(getSystemMemInfo() as $key => $valor){
   echo "$key: $valor<br>";
}
?>

Result:
