查找Laravel应用程序实例正在使用多少RAM？
我需要弄清楚特定的Laravel应用程序正在使用多少RAM/CPU，但是到目前为止，当前代码显示了整个系统的用法。
我可以如何检查只有一个 laravel应用程序使用的RAM/CPU多少？ （Windows任务管理器如何显示每个程序的CPU/RAM用法 - 但对于Web应用程序[尤其是Laravel，但欢迎使用Vanilla PHP解决方案]））
当前代码下面...
web.php：
...
Route::get('/details', function () {
//RAM usage
$free = shell_exec('free');
$free = (string) trim($free);
$free_arr = explode("\n", $free);
$mem = explode(" ", $free_arr[1]);
$mem = array_filter($mem);
$mem = array_merge($mem);
$usedmem = $mem[2];
$usedmemInGB = number_format($usedmem / 1048576, 2) . ' GB';
$memory1 = $mem[2] / $mem[1] * 100;
$memory = round($memory1) . '%';
$fh = fopen('/proc/meminfo', 'r');
$mem = 0;
while ($line = fgets($fh)) {
$pieces = array();
if (preg_match('/^MemTotal:\s+(\d+)\skB$/', $line, $pieces)) {
$mem = $pieces[1];
break;
}
}
fclose($fh);
$totalram = number_format($mem / 1048576, 2) . ' GB';
//cpu usage
$cpu_load = sys_getloadavg();
$load = $cpu_load[0] . '% / 100%';
return view('details',compact('memory','totalram','usedmemInGB','load'));
});
...

I need to figure out how much RAM/CPU a particular Laravel app is using, but so far the current code shows the entire system's usage.
How can I, instead, check how much RAM/CPU only one Laravel app is using? (kind of how the Windows task manager shows each program's CPU/RAM usage- but for web apps instead [particularly Laravel, but vanilla PHP solutions are welcome])
Current code below...
web.php:
...
Route::get('/details', function () {
//RAM usage
$free = shell_exec('free');
$free = (string) trim($free);
$free_arr = explode("\n", $free);
$mem = explode(" ", $free_arr[1]);
$mem = array_filter($mem);
$mem = array_merge($mem);
$usedmem = $mem[2];
$usedmemInGB = number_format($usedmem / 1048576, 2) . ' GB';
$memory1 = $mem[2] / $mem[1] * 100;
$memory = round($memory1) . '%';
$fh = fopen('/proc/meminfo', 'r');
$mem = 0;
while ($line = fgets($fh)) {
$pieces = array();
if (preg_match('/^MemTotal:\s+(\d+)\skB$/', $line, $pieces)) {
$mem = $pieces[1];
break;
}
}
fclose($fh);
$totalram = number_format($mem / 1048576, 2) . ' GB';
//cpu usage
$cpu_load = sys_getloadavg();
$load = $cpu_load[0] . '% / 100%';
return view('details',compact('memory','totalram','usedmemInGB','load'));
});
...

请勿使用Laravel检测Laravel从您的服务器资源中消耗多少资源，而是使用服务器监视工具。
是一个非常好的命令，我们可以用来检测哪些应用程序使用的服务器最多，多少！
现在，如果您对服务器良好 https://grafana.com/grafana.com/grafana/dashboards/ 检测RAM的使用等...
有一个很好的文档，但是如果您遇到任何麻烦，请发表评论，我将为您提供两个应用程序的服务器安装！
谢谢
Do not use Laravel to detect how much resources is Laravel consuming from your server resources, instead I would use server monitoring tools.
Is a very good command that we can use to detect what apps are using our server the most and how much!
Now if you are good with servers, I advise you to use https://prometheus.io/, Use it with https://grafana.com/grafana/dashboards/ to detect the RAM usage etc...
There is a good documentation but if you faced any troubles, please comment and I'll help you with the server installation for both apps!
Thanks
或者，您可以使用 laravel-debugbar ，您可以在其中看到应用程序的内存量。
但是，这有点欺骗性，因为Debugbar本身来自记忆，因此更多的是出于信息目的。
Or you can use laravel-debugbar, where you can see how much memory the application consumes.
But, it's a little deceptive because the debugbar itself takes from memory, so it's more for informational purposes.
您可以获取Web服务器线程的内存使用量，而不是完全需要的，而是非常接近。
假设您使用Linux系统（在我的CentOS7+XAMPP环境上进行了测试）：
用于Windows（在我的Win10+XAMPP环境中进行了测试）：
You could get the memory usage of you web server thread, not exactly what you need but very close.
Suppose you use linux system (tested on my CentOS7+XAMPP environment):
For windows (tested on my Win10+XAMPP environment):
