@V@no

With this:

Code: [Select]

$serverinfo = 0;
if($uptime = @exec("uptime")) {
     if(preg_match("/averages?: ([0-9\.]+),[\s]+([0-9\.]+),[\s]+([0-9\.]+)/", $uptime, $match)) {
         $match[1] *= 100;
         $match[2] *= 100;
         $match[3] *= 100;

         $serverinfo = 1;
     }
}


echo "Server-Auslastung der letzten Minute: $match[1]% <br>"; //Zeigt die aktuelle Server-Auslastung
echo "Server-Auslastung der letzten 5 Minuten: $match[2]% <br>"; //Zeigt die Auslastung vor 15 Minuten
echo "Server-Auslastung der letzten 15 Minuten: $match[3]% <br>"; //Zeigt die Auslastung vor 30 Minuten

Acidgod, do you know in what "mesurement" the CPU usage returned by "uptime" binary? I don't... and if use the method you showed, it would show sometimes 300% on my server - which is obviosly impossible. Wonder if you know..

@}{iJacK:
Lets try this first, see if you'd like it.
If server reached NN% CPU usage, let the current page request wait 1 second (sleep), then check again CPU usage, if its still too high, sleep for 1 more second, continue put the process to sleep unitll CPU usage droped, once its droped - continue executing the script.
This will endup slowing down opening pages, and will not return any error messages (unless ofcourse client (browser) get timeout, which hopefuly will not happend too often or at all.)
If you like this idea, I'll try do that using Acidgod's method.
In mean time, create a test.php file with the following content, upload it to your server and start it with the browser. See if it return any error messages, or some numbers.

Code: [Select]

<?php
echo exec("uptime");
?>

The Script shows the load averages of the Server...

Read this for more Informations:
http://en.wikipedia.org/wiki/Load_(computing)

And this:
http://www.teamquest.com/resources/gunther/ldavg1.shtml

And the load averages is a good thing for that...
But the Limit must over 200% and not 90%, on Linux Server the max Limit is not 100% and itīs varied on different Systems... (o:

I know this is an old thread but this is almost what I'm looking for.

I would LOVE a mod that will limit the number of *non-registered* users when loads are heavy.
For example, 200 total users allowed with (already logged in) *Registered* users given first priority, and a "we're too busy right now" message for non-registered users exceeding the 200 users mark.

Possible?

V@no, would it be possible to hire you for a mod like this?
I would share it with the community.

There are some alternatives...
Limit number of Users on the site at one time? (Instead of server load).

This thread has something similar but it looks like all users would have to be registered users:

I belive I've posted somewhere the code for that...I'll try to find it, but no promises
