I recently found this cool little script for checking which services are running on my webserver. For true effectiveness though, you should host this script on a second webserver so you can get feedback from the script even if your site is down.

PHP Code:

  <?php

function check_port($port) {

    $conn = @fsockopen("127.0.0.1", $port, $errno, $errstr, 0.2);

    if ($conn) {

        fclose($conn);

        return true;

    }

}

 
function server_report() {

    $report = array();

    $svcs = array('21'=>'FTP',

                  '22'=>'SSH',

                  '25'=>'SMTP',

                  '80'=>'HTTP',

                  '110'=>'POP3',

                  '143'=>'IMAP',

                  '3306'=>'MySQL',);

    foreach ($svcs as $port=>$service) {

        $report[$service] = check_port($port);

    }

    return $report;

}

 
$report = server_report();

?>

<table>

    <tr>

        <td>Service</td>

        <td>Status</td>

    </tr>

    <tr>

        <td>MySQL</td>

        <td><?php echo $report['MySQL'] ? "Online" : "Offline"; ?></td>

    </tr>

    <tr>

        <td>HTTP</td>

        <td><?php echo $report['HTTP'] ? "Online" : "Offline"; ?></td>

    </tr>

    <tr>

        <td>SSH</td>

        <td><?php echo $report['SSH'] ? "Online" : "Offline"; ?></td>

    </tr>

    <tr>

        <td>FTP</td>

        <td><?php echo $report['FTP'] ? "Online" : "Offline"; ?></td>

    </tr>

    <tr>

        <td>SMTP</td>

        <td><?php echo $report['SMTP'] ? "Online" : "Offline"; ?></td>

    </tr>

    <tr>

        <td>POP3</td>

        <td><?php echo $report['POP3'] ? "Online" : "Offline"; ?></td>

    </tr>

    <tr>

        <td>IMAP</td>

        <td><?php echo $report['IMAP'] ? "Online" : "Offline"; ?></td>

    </tr>

</table>

It is not very complex and gives you a nice quick overview of your server

Maybe this will help, I use it myself. Just open a sock to some port, see if it's open, and you know it's ok

Of course there are better alternatives which even check if a webpage works and such, but well, this does do the job for me.

function scanport($host, $port, $beschrijving){
$sock = @fsockopen($host, $port, $num, $error, 2);
if ($sock) {
$status = $beschrijving.'Up ';
fclose($sock);
unset($sock);
} else {
#Fout! Nog een keer controleren!
unset($sock);
$sock = @fsockopen($host, $port, $num, $error, 2);
if ($sock) {
$status = $beschrijving.'Up ';
fclose($sock);
unset($sock);
} else {
# Nu is het dus echt mis
$status = $beschrijving.'Down ';
unset($sock);
}
}
echo $status;
}
