Hmm i cam getting the following error:

"PHP Notice: Undefined index: debug in C:\Inetpub\wwwroot\ns\index.php on line 67"

which is:

if( $_GET["debug"] == "true" ) { $namesonly = false; }

Guys, can I just throw my 2 cents worth in here?

We have a system kind of like what you've all been doing at our school (written myself etc, like much of you!), however i found a problem... once some of the brighter kids figured out that it pinged and connected to several servers to see if they were up (wasnt that hard really... it's the most obvious way of doing it), they spammed it by refreshing a page.

Now one person doing this doesnt dent the intranet server... but multiply that by a class and boy does it go down quick.

We solved this by making a php script which did all the checks, then put the results into a DB. This script is run once a minute and can only be run by the server.

Then the public side of the system, simply iterates through the database and shows the systems and their status.

This might not be a problem for your schools... but it was for ours as soon as the cat got out the bag!

it's a debug notice... you dont have to listen to it. nothing is wrong that will stop it working. Simple solution is, disable debug notices in your php.ini.

E.g. mine is

Code:

error_reporting  =  E_ALL & ~E_NOTICE

This shows all errors except for notices and coding standards warnings.

I see, then in that case i am just having the same problem as John D. Must be something to do with checking the result of the ping command.

We now use Monit running on a linux box and checks essential ports on our other servers. Our monitrc file is here.

I can see this being a problem in our school too, some of the more clever kids have found out differnt commands and are messing around, not long before they figure out the ping command.

Any chance of seeing your php script.

**DSapseid** · 31st March 2008, 09:52 AM

I can now get it to display in 3 columns but they are 'under' each other (see image). How can i tell it to display these 'next' to each other.

I know the reason I was not getting reports of down servers was due to folk error (once I turned debug on the error msg came up)

As for undefined error think this will work at line 62:-

Code:

if (isset($_GET["debug"])) {
if( $_GET["debug"] == "true" ) { $namesonly = false; }
} else {
}

Ok got bored

Started editing (or maybe hacking away with a big pick axe) the script so will put my version up.

All credit to above people who made this script etc.

Main difference are : -

- adding the above code to stop the debug error
- Adding a msg at the bottom of the screen that says how many and what servers are down (the as I call it the idiots msg as I can't be bothered to work the table out)
-If add ?portal=true to the end give you a cutdown view you can add to a portal

Code:

<?php

$hosts['10.56.156.16'] = 'LHS-SR-001';
$hosts['10.56.156.18'] = 'LHS-SR-002';
$hosts['10.56.157.16'] = 'LHS-SR-SIMS';
$hosts['10.56.156.15'] = 'Internal Support Server';


$ReportedErrors= "";
$portalview ="";



if (isset($_GET["portal"])) {
if( $_GET["portal"] == "true" ) { $portalview = true; }
} else {
}


						
?>

I have asked fn to put this thread on the wiki...

Thought might be interested just got bored again and started hacking the script and now made it so that when added portal=true value to end of the url it either displays either

"All Servers Are Fine" or
"There Are Currently 1 Connection Errors. The Servers That Have Errors Are.."

Again all credit goes to above people I just hacked away the code.

Code:

<?php

$hosts['90.56.156.16'] = 'LHS-SR-001';
$hosts['10.56.156.18'] = 'LHS-SR-002';
$hosts['10.56.157.16'] = 'LHS-SR-SIMS';
$hosts['10.56.156.15'] = 'Internal Support Server';


$ReportedErrors= "";
$portalview ="";

function ping($host){
	$hostconnect = "Ping request could not find host ". $host . ". Please check the name and try again." ;
	$ipconnect = "    Packets: Sent = 1, Received = 0, Lost = 1 (100% loss)," ;
	$rv = exec("ping $host -n 1 -w 1");
	if( $ipconnect == $rv )	{
		return false;
	} else {
		if( $hostconnect == $rv ) {
		return false;
	} else {
		return true;
	}
	}
}

if (isset($_GET["portal"])) {

if( $_GET["portal"] == "true" ) { $portalview = true; }
} else {
}
