Howdy,

I've had a nose about the internet and don't seem to be able to find such a script, but surely its got to be possible?

What I'm looking for is a php script that I can poll one or more source game servers and if they're down for it to email one or more email addresses.

Have you seen such a script before?

Matt

Here's something that does what you want, stick it on a cron so it runs say... every 30 minutes or so.

PHP Code:

<?php
    
    //Server array
    //IP => PORT
    $servers = array(
        '1'                 =>     '2',
        'server.google.de'    =>    '27015',
        'vsh.dcsrvdls.com'    =>    '27015'
        
    );
    
    //Email array
    $emails = array(
        '[email protected]',
        '[email protected]'
    );
    
    $onlineCheckTimeout = 5;    //Timeout time (default = 5)
    $onlineCheckAttempts = 3;    //How many times to check the server(s) (default = 3)
    $onlineCheckInterval = 5;    //Interval time (in seconds) between making those (default 3) checks (default = 5)
    
    $message = 'Hello!'."\r\n\r\n".'It appears one or more servers are offline, as they failed to respond to the online check. Those servers are as follows:'."\r\n\r\n";
    
    
    
    //Our function that does the check
    function serverOnline($ip,$port){
        global $onlineCheckTimeout, $onlineCheckAttempts, $onlineCheckInterval;
        for($i=0,$l=$onlineCheckAttempts;$i<$l;++$i){
            $online    = @fsockopen($ip,$port,$errno,$errstr,$onlineCheckTimeout);
            if($online)return true;
            if($i!==$l-1)sleep($onlineCheckInterval);
        }
        return false;
    }
    
    ini_set('max_execution_time', 300);
    
    foreach($servers AS $ip => $port){
        
        if(!serverOnline($ip, $port)){
            echo 'Server: ',$ip,':',$port,' is offline, emailing administrators...<br />',"\r\n";
            foreach($emails AS $emailAddr){
                mail($emailAddr, 'Server Checker Script: Server: '.$ip.':'.$port.' is offline!', $message.$ip.':'.$port."\r\n", 'X-Mailer: PHP/'.phpversion());
            }
        }
        
    }
    
?>

It could be improved, but it does what you want. If a server is offline, it'll email the admins who are specified in the array. It'll do several checks first though.

i would recommend a plugin that requests a php page using sockets extension, it would send a mail everytime the server crashed

@Adjo: server ports are udp ports, that means your script wouldnt work, as its a connection-less protocol, so you would have to send a packet to the server, for example A2S_PING and if it replies then its online. Also, fsockopen fn needs to be modified as well like this:

@fsockopen("udp://".$ip, ...)

Weird, the code I posted worked fine for my test server, when tested on my webserver... when it was online, no email was sent, and when it was offline, an email was sent. Could you test it to see if you get any different results?

hmm, interesting, i thought srcds only listens on udp, then excuse me and keep up the good work

SRCDS listens on udp for gameconnections and tcp for rcon. both usually on the same port.

This looks great, pretty much what I was looking for. However I would like the script to execute a restart script as well as send an email if a server is down. I can figure that much out by adding

PHP Code:

 (exec('c:\scripts\restart_server_1.bat') 


but how could it work for multiple servers, so it ran the correct .bat for the ip:port that was not responding?

Try this out, haven't been able to test if the exec(); part works - because I don't have any restart script to test it with, but it should, hopefully.

PHP Code:

<?php
    
    //Server array
    //SERVER:PORT => RESTART SCRIPT
    $servers = array(
        '1:2'                        =>    'some-path-to-the-restart-script',
        'server.google.de:27015'    =>    'some-path-to-the-restart-script',
        'vsh.dcsrvdls.com:27015'    =>    'some-path-to-the-restart-script',
        '127.0.0.1:27017'            =>    'some-path-to-the-restart-script'
    );
    
    //Email array
    $emails = array(
        '[email protected]',
        '[email protected]',
        'hihi@bye'
    );
    
    $onlineCheckTimeout = 5;    //Timeout time (default = 5)
    $onlineCheckAttempts = 3;    //How many times to check the server(s) (default = 3)
    $onlineCheckInterval = 5;    //Interval time (in seconds) between making those (default 3) checks (default = 5)
    
    $message = 'Hello!'."\r\n\r\n".'It appears one or more servers are offline, as they failed to respond to the online check. Those servers are as follows:'."\r\n\r\n";
    
    
    
    //Our function that does the check
    function serverOnline($ip,$port){
        global $onlineCheckTimeout, $onlineCheckAttempts, $onlineCheckInterval;
        for($i=0,$l=$onlineCheckAttempts;$i<$l;++$i){
            $online    = @fsockopen($ip,$port,$errno,$errstr,$onlineCheckTimeout);
            if($online)return true;
            if($i!==$l-1)sleep($onlineCheckInterval);
        }
        return false;
    }
    
    ini_set('max_execution_time', 300);
    
    foreach($servers AS $host => $script){
        
        $boom = explode(':', $host);
        
        if(!serverOnline($boom[0], $boom[1])){
            echo 'Server: ',$boom[0],':',$boom[1],' is offline, attempting to restart server, and email the administrators...<br />',"\r\n";
            exec($script);
            foreach($emails AS $emailAddr){
                mail($emailAddr, 'Server Checker Script: Server: '.$boom[0].':'.$boom[1].' is offline!', $message.$boom[0].':'.$boom[1]."\r\n", 'X-Mailer: PHP/'.phpversion());
            }
        }
      
    }
    
?>

Thanks Adjo that works great!

One php question though (only just starting to get to grips with php...). Where it says

PHP Code:

 $servers = array(
        '1:2'                        =>    'some-path-to-the-restart-script',
        'server.google.de:27015'    =>    'some-path-to-the-restart-script',
        'vsh.dcsrvdls.com:27015'    =>    'some-path-to-the-restart-script',
        '127.0.0.1:27017'            =>    'some-path-to-the-restart-script'
    ); 


is there a reason why you can't put

PHP Code:

 '1'                        =>  '2'  =>  'some-path-to-the-restart-script',
