Detecting CPU load with PHP

Hi All,

There is some serious issue with one of my servers. So, I thought of writing a small PHP script which gives me the CPU load just like the top command in linux environment? If any of you have done this, please provide me any pointers/directions.

I would appreciate any help in this regard. Thanks in advance!!

I haven't tried this myself but this link seem to have what you are looking for forums.invisionpower.com/index.php?showtopic=156890 .

 

I would think php-sysinfo would be a good starting point. I think it is open source so maybe you can contribute some additional functionality

 

You might be able to open '/proc/loadavg' and read out the contents. Here's what my box reports:

0.04 0.02 0.00 1/92 7089

Code (markup):

First three numbers will be average load over the last 1, 5 and 15 minutes. I have no idea what the next two are, though the last number looks like the current highest (or next) process id.

You might also be interested in '/proc/meminfo'.

Cryo.

 

Hi All,

only works on linux, dont forget to give me some of that green rep

	$uptime1 = @exec('uptime');
	preg_match("/averages?: ([0-9\.]+),[\s]+([0-9\.]+),[\s]+([0-9\.]+)/",$uptime1,$avgs1);
	$uptime1 = explode(' up ', $uptime1);
	$uptime1 = explode(',', $uptime1[1]);
	$uptime1 = $uptime1[0];
	$start1=mktime(0, 0, 0, 1, 1, date("Y"), 0);
	$end1=mktime(0, 0, 0, date("m"), date("j"), date("y"), 0);
	$diff1=$end1-$start1;
	$days1=$diff1/86400;
	$percentage1=($uptime1/$days1) * 100;
	$load1=$avgs1[2];

PHP:

 

You all do things the complicated way

<?php
echo shell_exec('top -b -n 1');
?>

PHP:

You may want to format it or just return it as regular text
