TOP Server Load on AdminCP homepage
Mod Version: 1.3, by Adult SEO

This mod will add the top server load statistics in your vBulletin admincp (if your server installation allows execution of programs via PHP)



Update (V.1.2)

Added kill process function to be able to kill a process with a click of the button.

Note: this will require the ability to execute kill -9 process_id from PHP exec();



Update (V.1.3)

Added SuperAdministrator check, to allow just super admins to see and manage server processes.

This addition was suggested by accludetuner

Got this working on 3.8.2. I have it using the hook of "admin_index_main3". I also made slight change to the code to only allow Super Administrators to be able to view/kill processes due to the possible problems an unknowing user could cause. Here's my code:

PHP Code:

if (in_array($vbulletin->userinfo['userid'], preg_split('#\s*,\s*#s', $vbulletin->config['SpecialUsers']['superadministrators'], -1, PREG_SPLIT_NO_EMPTY)) )
{

/* Server Load */
if ($_REQUEST["kill_process"] && is_numeric($_REQUEST["kill_process"])) {
        $process_id = $_REQUEST["kill_process"];
        if ($_POST["no"]) {
        
        } elseif ($_POST["yes"]) {
            exec("kill -9 ".$process_id."");
            print_table_start();
            print_table_header('<a name="killprocess"></a>TOP - Server Load - Kill Process '.$process_id.'',1);
            print_description_row('Process killed!',false,1);
            print_table_footer(2, '', '', false);
        } else {
            exec('ls -la /proc/'.$process_id.'/', $procdata, $error );
            $proctxt = '';
            foreach ($procdata as $procline) {
                $proctxt .= trim($procline)."\n";
            }
            print_table_start();
            print_table_header('<a name="killprocess"></a>TOP - Server Load - Kill Process '.$process_id.'',1);
            print_description_row('<form method="post" action="index.php?do=home&kill_process='.$process_id.'#killprocess">
                Are you sure you want to kill this process? 
                <div style="padding:10px;"><textarea style="width:550px;height:200px;">'.$proctxt.'</textarea></div><input type="submit" name="yes" value="Yes"> <input type="submit" name="no" value="No">
            </form>',false,1);
            print_table_footer(2, '', '', false);
        }
    }

    print_table_start();
    print_table_header('TOP - Server Load',12);
    exec('top n 1 b i', $top, $error );
    
    $is_toptable = false;
    foreach ($top as $topline) {
        $topline = trim($topline);
        if (!$topline) { continue 1; }
        if (!$is_toptable && !preg_match('|^PID|Ui',$topline)) {
            if (preg_match('|^top - (.*)$|Ui',$topline,$out)) {
                print_description_row('<b>TOP:</b> '.$out[1],false,12);
            } else {
                if (preg_match('|^([^:]+): (.*)$|Ui',$topline,$out)) {
                    print_description_row('<b>'.$out[1].':</b> '.$out[2],false,12);
                } else {
                    print_description_row($topline,false,12);
                }
            }
        } else {
            $topvals = preg_split('|[ ]+|s',$topline);
            if (!$is_toptable) {
                foreach ($topvals as $key => $value) {
                    $topvals[$key] = '<b>'.$value.'</b>';
                }
            } else {
                $topvals[0] .= ' <a href="index.php?do=home&kill_process='.$topvals[0].'#killprocess" style="color:red;">X</a>';
            }
            print_cells_row(array(
                    $topvals[0],
                    $topvals[1],
                    $topvals[2],
                    $topvals[3],
                    $topvals[4],
                    $topvals[5],
                    $topvals[6],
                    $topvals[7],
                    $topvals[8],
                    $topvals[9],
                    $topvals[10],
                    $topvals[11]
                ), 0, 0, -5, 'top', 1, 1);
            
            $is_toptable = true;
        }
    }
    print_table_footer(2, '', '', false);
    
}
