Server Load PHP Script

[TheJeffsta]

Does anyone know of any PHP code/script that displays the current (when the page is loaded) server load?

I don't need uptime, I've already got uptime at http://www.thejeffsta.x10hosting.com/Status/Uptime.php (modified to make it reload every 5 seconds but dont really know why as it only adds 5 seconds to the uptime count).

Also I have already got the server services status script, http://www.thejeffsta.x10hosting.com/Status/x10Hosting.php

Sort of like the server load in the following forum members signature:

try this php function

the function returns the calculated value so use it like this:
$load = getServerLoad();
echo "Server load: " . $load;

note, when the server is running windows, it can add a full second to your scripts execution time. by default it will not perform the calculation for windows, but you can force it to by changing the parameter '$windows = 0' to '$windows = 1'.

function getServerLoad($windows = 0) {
    $os = strtolower(PHP_OS);
    if (strpos($os, "win") === false) {
        if (file_exists("/proc/loadavg")) {
            $data = file_get_contents("/proc/loadavg");
            $load = explode(' ', $data);
            return $load[0];

        } elseif (function_exists("shell_exec")) {

            $load = explode(' ', `uptime`);
            return $load[count($load)-1];

        } else {

            return false;
        }

    } elseif($windows) {

        if(class_exists("COM")) {
            $wmi = new COM("WinMgmts:\\\\.");
            $cpus = $wmi->InstancesOf("Win32_Processor");
     
             $cpuload = 0;
             $i = 0;

            if(version_compare('4.50.0', PHP_VERSION) == 1) {
                // PHP 4
                while ($cpu = $cpus->Next()) {
                    $cpuload += $cpu->LoadPercentage;
                    $i++;
                }

            } else {

                // PHP 5
                foreach($cpus as $cpu) {
                    $cpuload += $cpu->LoadPercentage;
                    $i++;
                }
            }

             $cpuload = round($cpuload / $i, 2);
             return "$cpuload%";

        } else {

            return false;
        }
    }
}

I use this:​

<?php
$uptime = @exec('uptime');
preg_match("/averages?: ([0-9\.]+),[\s]+([0-9\.]+),[\s]+([0-9\.]+)/", $uptime, $avgs);
$uptime = explode(' up ', $uptime);
$uptime = explode(',', $uptime[1]);
$uptime = $uptime[0] .', '. $uptime[1];
$start = mktime(0, 0, 0, 1, 1, date('Y'), 0);
$end = mktime(0, 0, 0, date('m'), date('j'), date('y'), 0);
$diff = $end - $start;
$days = @($diff / 86400);
$percentage = @($uptime / $days) * 100;
$load = $avgs[1] + $avgs[2] + $avgs[3];
$load = $load / 3;
$load = round($load, 3);

// $load holds the load.

?>

Either way works though.

Edit: *nix only

 

[TheJeffsta]

It doesnt work

It only returns a blank page.

 

[Bryon]

Which example posted? And how are you calling/using it?

 

[jensen]

tried both examples and they don't work.

(Am running on another host because this host down for maintainance.)

 

[Bryon]

How are you calling/using it?

 

[TheJeffsta]

Doesnt that code you gave us work by itself?

 

[Torch]

You need to add "echo" to make them work for themselves. For Bryon's code you need to add

echo "Server uptime: $uptime";
echo "<br>";
echo "Server load: $load%";

after "// $load holds the load."

Yep, he's right with mine. You need to echo the variable holding the uptime to actually "see it."

For the function that someone else posted, you need to call the function and echo the output.

Example:

## 1 ##
echo getServerLoad();

## 2 ##
$output = getServerLoad();

   // Other code here possibly..

echo $output;
