I'm trying to show the use of the server's processor with PHP. Server is Windows with IIS. I've already tried using:
exec("wmic /node:localhost path Win32_Processor where DeviceID='CPU0' get LoadPercentage", $out);
exec("wmic cpu get loadpercentage", $out);
And a few more ways, but it always returns empty. Does anyone know if you need any special permission to do this, or do you have any other ideas?
One option is to use phpSysInfo
Description
phpSysInfo is a script that shows information about your system.
phpSysInfo >
In addition to showing CPU usage, it shows even more than you need, such as:
PS: it does not use exec , it reads all information straight from /proc .
Example of what it can do.
There is also sys_getloadavg() , which can be a good move.
Note
This function is not implemented on the Windows platform
Font - em English
function retornar_uso_cpu(){
$uso = sys_getloadavg();
return $uso[0];
}
<p><span class="description">Server CPU Usage: </span> <span class="result"><?= retornar_uso_cpu() ?>%</span></p>
An option that works in Windows would be:
Note
This method is not so fast, so be careful about the amount of calls. If something goes wrong (eg not having sufficient access permissions), it returns 0 .
<?php
function get_server_load() {
if (stristr(PHP_OS, 'win')) {
$wmi = new COM("Winmgmts://");
$server = $wmi->execquery("SELECT LoadPercentage FROM Win32_Processor");
$cpu_num = 0;
$load_total = 0;
foreach($server as $cpu){
$cpu_num++;
$load_total += $cpu->loadpercentage;
}
$load = round($load_total/$cpu_num);
} else {
$sys_load = sys_getloadavg();
$load = $sys_load[0];
}
return (int) $load;
}
?>
First check where the wmic executable is.
where wmic . C:\Windows\System32\wbem\WMIC.exe
shell_exec("C:\Windows\System32\wbem\WMIC.exe cpu get loadpercentage");
