Server Load and Script excecution

pablodelapena

Ok, Ive seen this on a few sites where it tells you how much laod is on the server and how long the script took to excecut. Id be interested to know if there is a function that does this or if its more complicated than that!

Ive tried php.net and found nothing!

phpmaven

<?php
// Record start time.
$start = time();
// Do your processing here
// Record end time
$end = time();
echo "Script took " . strval($end - $start) . " seconds!";
?>

use microtime() to get even more precision.

brilliant, what about finding out the laod on the server? Ive seen this is vBulletin boards but not ben able to findit in the source code??

I am not sure how they got server load. What do they actually mean by server load is it CPU usage percentage, number of users, etc.....? I know if you are looking for CPU percentage i think you can get it from the proc file system, but that i think is only on linux boxes. win32 systems could probably get it by using a win32 api call, not sure which api call, there are so many. You could also maybe use the exec() and call an external program that will return the current cpu usage or whatever. These are just ideas.

wow, thanks! sounds a li ttle complex for me. If you go to www.scoznet.com and look at the bottom it tells you how many quieries used, script excecution time GZIP:enabled and finally Server Load. thats all I'm after!

yep he is using the proc file system on linux box. read about it sometime, it offers a lot of cool funcitonality, cpu usage, memory load, all sorts of cool stuff.

if ( @file_exists('/proc/loadavg') ) {
if ( $fh = @fopen( '/proc/loadavg', 'r' ) ) {
$data = @fread( $fh, 6 );
@fclose( $fh );
$load_avg = explode( " ", $data );
$server_load = trim($load_avg[0]);
$server_txt = "".$lang_template['server_load'].": $server_load";
} else {
$data = system('uptime');
@preg_match('/(.):{1}(.)/', $data, $matches);
$load_arr = explode(',', $matches[2]);
$server_load = trim($load_arr[0]);
$server_txt = "".$lang_template['server_load'].": $server_load";
}

} else {
$server_txt = "";
}
