Is there a tool available for monitoring server status with HTML/CSS

I am interested in a way to create an HTML or CSS code that can ping an address or IP every 10 minutes to determine if it is sending back a signal. If a signal is received, I want the status on my website to display as 'online'. In case there is no signal, I would like the text on my webpage to show 'offline'. Configuring this to work with multiple servers seems daunting to me at this point. So far, I have only been able to figure out how to do this using cron jobs, but since I'm running Windows 7, scripting it in the emulators I found has proven difficult due to my lack of experience. As a beginner in HTML and CSS, this challenge feels quite overwhelming for me.

Any assistance with this matter would be highly appreciated. Thank you in advance.

Answer №1

Is it possible to create a file on an external server?

If yes, include a small stylesheet there that modifies the following HTML:

<span class="active">Active</span>
<span class="inactive">Inactive</span>

transforming this CSS (on your server):

.active { display: none; }
.inactive { display: inline; }

to this:

.active { display: inline; }
.inactive { display: none; }

Ensure you link them so that the external server's stylesheet is the final one in your HTML header.

Nevertheless, this method using just CSS cannot be repeated every ten minutes - for that, JavaScript is required.

Create a JSON-P request to the external server, set the text default to "inactive" in your HTML, and change it to "active" if the JSON-P request is successful. (JSON-P should not return any errors.) However, you must have a custom page on that external server to return the JSON data, even if it's empty.

If you do not have permission to write on the external server, then there may not be much you can do in this case.

To incorporate this functionality on your webpage, you'll need to include some JavaScript code.

One approach is to make an AJAX request to check if the page is online - a successful AJAX request will return a 200 status code indicating that the page has loaded. If the page is hosted on a different domain than your test page, you may need to enable Cross Origin Requests (CORS) or use JSONP response, or set up a proxy page on your server.

Keep in mind that a failed request doesn't necessarily mean the website itself is offline - it could also be due to a dropped connection on your end.

To set up a server base script, you'll need to use PHP or ASP along with JavaScript that includes AJAX on the client side.

Consider using the jQuery library for JavaScript, which can help you save time (http://jquery.com/).

Here's an example of how your HTML structure could look:

<div class='serverstatus'></div>

For PHP, you would need to create a script like this:

$host = 'Your IP';
$port = your.port;
// Specify the Server Info [IP/PORT]
$timeout = 1;
// Establish a connection to the specified IP and port to check if it's responsive
$handler = fsockopen($host,$port,$errcd,$errstr,$timeout);
if($handler){   
   echo "1";
} else {
   echo "0"; 
} 
fclose($handler);

Next, for JavaScript:

Here is a simple Ajax function:

setTimeout(function() {$.ajax({
    url:'phpfile.php',
    type: 'GET',
    success: function(data){
        if (data == "1") {
            $(".serverstatus").html("Online");
        }
        else if (data == "0") {
            $(".serverstatus").html("Offline");
        }
        else {
            $(".serverstatus").html("Undefined");
        }

    }
});},600000);

Note: jQuery Library is required for this functionality.

CSS stands for Cascading Style Sheets and is used solely for designing purposes. It cannot be used for scripting. HTML, on the other hand, is used for creating content and not for scripting.

If you want to set up connections with external sources and implement live updates, you'll need to learn PHP or ASP for the connection part and JavaScript for real-time updates.
