This is a old plugin that i make in the earling times of vBulletin 3.5

This plugin allow to you disable searches when the load average reaches a defined level.

• Can exclude user groups of the search restriction
• Users with search restricted can use google integrated search (by the plugin)

The code

PHP Code:

 
     $Groupids = explode(',', $vbulletin->options['Allowed_Groups']);
 
     if(is_member_of($vbulletin->userinfo, $Groupids))
     {
      $SearchAllowed = true;
     }
    //$SearchAllowed = is_member_of($vbulletin->userinfo, explode(',',$vbulletin->options['Allowed_Groups'])) ? true : false;
 
    if (!$SearchAllowed)
    {
 
      if ($load = @file_get_contents("/proc/loadavg"))  //standard linux style
       $loadavg = explode(' ', $load);  
      elseif ($load=@exec('uptime'))  //unix style
       preg_match('/averages?: ([0-9.]+),[s]+([0-9.]+),[s]+([0-9.]+)/',$load, $loadavg);
      elseif ($load = @`sysctl vm.loadavg|cut -d" " -f3-5`) //BSD style
       $loadavg = explode(' ', $load);  
 
      if (trim($loadavg[0]) > $search_load)  
      {
        $navbits = construct_navbits($navbits);
               eval('$navbar = "' . fetch_template('navbar') . '";');
               eval('print_output("' . fetch_template('Danny_Restrict') . '");');
      }
     } 


The plugin work with linux, freeBSD and unix servers not in WINDOWS.
Be sure that you allow access to /proc/loadavg in open_basedir in php.ini
