excellent idea! can you tell us how it actually works?

[Depreciated]

wow interest in this mod in 5mins? excellent!!

but in short this uses the linux command 'sys_getloadavg()' to get the load of the server and is set to a default of 3 and can be changed if you wish (will have an admin option in v1.2 of the mod) and then shows a warning if it's the same or above of the set value and if it is it'll display the floating html/javascript warning

[flapjack]

neat thanks for the answer
I assume this is a standard command, and is not being restricted somehow by providers?

[Depreciated]

i'm not totally sure as i've only tested this on my own linux dedicated server and simply can't test it on all hosts but some right restrict it but i'm guessing 99% won't

[Depreciated]

if anyone can help with adding a selectable 'load' amount option in admin settings i'd be very grateful

[Rafferty]

I cant find anywhere in Admin to enable/disable, where is it?

After reading this post I though this would be a good idea to have in my chat system. So I have been building on your idea and been adding compatibility. Untested though my function, I think I have windows support by using PHP's passthru function to execute a Windows OS command and older PHP support by loading the loadavg file or if not available executing a shell command.

Great mod. Is there a chanse to port this for 1.1.11 versions?
I can help with adding to template if this can be done.

there we go support for smf v1.1.x but without the admin enable/disable option as i'm not sure how to do that on smf v1.1.x

Well don't know if I am going to implement this for 2-SI Chat but I have finished my load check script. This one will check PHP versions that support sys_getloadavg, lower versions of PHP that do not support this function and windows servers with PHP installed.

Note on Windows systems I could only get one load average so I went ahead and use the one load average for all three. Also I checked the windows server part of the script by using my command prompt and copying the output to a test script. It seems to work well but I do not have a windows server to test on.

$cpu[0] = load average 1
$cpu[2] = load average 2
$cpu[3] = load average 3

Your free to use any of this code for you mod, hope it will be useful.

if (function_exists('sys_getloadavg')) {

$cpu = explode(chr(32),file_get_contents('/proc/loadavg'));
} else {
$cpu = array_map("trim",explode(",",substr(strrchr(shell_exec("uptime"),":"),1)));
}
} else if (stristr(php_os, 'WIN')) {
ob_start();
passthru('typeperf -sc 1 "\processor(_total)\% processor time"',$status);
$content = ob_get_contents();
ob_end_clean();
if ($status === 0) {
if (preg_match("/\,\"([0-9]+\.[0-9]+)\"/",$content,$load)) {
$cpu[0] = $load[1];
$cpu[1] = $load[1];
$cpu[2] = $load[1];
}
}
}

wow that's out of my league lol wouldn't know what to do with it

Not too hard.

Checks if sys_getloadavg exist and if it does cpu equals sys_getloadavg().

Code Select Expand

   if (function_exists('sys_getloadavg')) {
      $cpu = sys_getloadavg();
If no function sys_getloadavg(older versions of php) and server os is not windows

Code Select Expand

   } else if (!function_exists('sys_getloadavg') && !stristr(php_os, 'WIN')) {
If the loadavg file exist load it else run a shell command to get the load average.

Code Select Expand

      if (file_exists('/proc/loadavg')) {
         $cpu = explode(chr(32),file_get_contents('/proc/loadavg'));
      } else {
         $cpu = array_map("trim",explode(",",substr(strrchr(shell_exec("uptime"),":"),1)));
      }

Else if the server is windows Use PHP's passthru function to execute a windows os command to get the load average of the machine.

Code Select Expand

   } else if (stristr(php_os, 'WIN')) {
      ob_start();
      passthru('typeperf -sc 1 "\processor(_total)\% processor time"',$status);
      $content = ob_get_contents();
      ob_end_clean();
      if ($status === 0) {
         if (preg_match("/\,\"([0-9]+\.[0-9]+)\"/",$content,$load)) {
            $cpu[0] = $load[1];
            $cpu[1] = $load[1];
            $cpu[2] = $load[1];
         }
      }
   }

Hope that helps you understand the script a little. After that part is ran, you can run something like this.

Code Select Expand


if($modSettings['Check_load'] && $cpu[0] > $modSettings['max_load']) {
echo 'Server has reached max load setting';
}


This is how it is used in my mod.

if ($modSettings['2sichat_load_chk']) {
doLoadCHK();
}
function doLoadCHK() {

global $modSettings;

if (function_exists('sys_getloadavg')) {

} else if (!function_exists('sys_getloadavg') && !stristr(php_os, 'WIN')) {

$cpu = explode(chr(32),file_get_contents('/proc/loadavg'));
} else {
$cpu = array_map("trim",explode(",",substr(strrchr(shell_exec("uptime"),":"),1)));

} else if (stristr(php_os, 'WIN')) {
ob_start();
passthru('typeperf -sc 1 "\processor(_total)\% processor time"',$status);

if ($status === 0) {

$cpu[2] = $load[1];
}
}
}

if ($cpu[0] && $cpu[0] > $modSettings['2sichat_max_load'] || $cpu[1] && $cpu[1] > $modSettings['2sichat_max_load'] || $cpu[2] && $cpu[2] > $modSettings['2sichat_max_load']) {
      if ($modSettings['2sichat_load_dis_chat']) {die();}
