Output of "watch" -> PHP

[AndroidApps]

Hi,

I'm looking for a way to display the output of watch -n 2 "free -m" to a webpage (or similar commands).
Any ideas?

Cheers

You can use system or exec.

Cheers, Look interesting!

I just figured I would do it look this:
watch -n 2 "ps aux | grep apache | wc -l > apache.txt"

Stay tuned

Ok, now I have this:

<?php
$cmd = "ps aux | grep apache | wc -l";
$output = system($cmd);
printf("Apache: $output\n");
echo "<br \>";

function get_memory() {
  foreach(file('/proc/meminfo') as $ri)
    $m[strtok($ri, ':')] = strtok('');
  return 100 - round(($m['MemFree'] + $m['Buffers'] + $m['Cached']) / $m['MemTotal'] * 100);
}
echo get_memory();
?>

Which results in:

90 Apache: 90 
67

How can I:
* remove the first '90'?
* make the 2nd '90' green untill '95' and red at or above '110'?
(Switch colors @ certain #)

Thanks for the help, I'm just a learner

<?php
$cmd = "ps aux | grep apache | wc -l";
$output = exec($cmd);

//Parse output
if ($output > 10)
{
$output = "Green time!";
}
printf("Apache: $output\n");
echo "<br \>";

function get_memory() {
  foreach(file('/proc/meminfo') as $ri)
    $m[strtok($ri, ':')] = strtok('');
  return 100 - round(($m['MemFree'] + $m['Buffers'] + $m['Cached']) / $m['MemTotal'] * 100);
}

?>

Edit: Checked your code, made some modifications for you. You STILL need to edit part of it, esp. the part on the output to make it green, right now as long as it is bigger than 10, it will make it 'green' to make it green you need to output something like

$output = "<font color=green>" . $output . "</font>"; 

Something along those lines. I'm tired. If you still have any problem's ill guide you along tmr

Awesome!

Made some modifications.
This script now turns the text red if there are more than 80 apache users or green if there are less.

Stay tuned for more

<?php
$cmd = "ps aux | grep apache | wc -l";
$output = exec($cmd);

//Parse output
if ($output > 80)
{
$output = "<font color=red>".  $output . "</font> apache users";

printf("Apache: $output\n");
echo "<br \>";
}
elseif ($output < 79)
{
$output = "<font color=green>".  $output . "</font> apache users";
printf("Apache: $output\n");
echo "<br \>";
}

function get_memory() {
  foreach(file('/proc/meminfo') as $ri)
    $m[strtok($ri, ':')] = strtok('');
  return 100 - round(($m['MemFree'] + $m['Buffers'] + $m['Cached']) / $m['MemTotal'] * 100);
}

?>

Fyi, system was outputting an extra 90 before Apache: 90, thats why i changed it to exec instead.

If you're interested, learn to use shorthand if's, makes your code look neater and shorter, although it is harder to read

You can enable stats page (and advanced) from httpd.cnf

Ah ok, I did not know exec could do the same as system
I'll google shorthand if's, never heard of it

Care to elaborate?
