Version 1.0 - works for most servers
Updated 1.1 - optimized code
Updated 1.2 - added names of uncached templates!

Okay, the original was by TECK. This is NOT based on his code - it is based on vB3's native code. If TECK wants me to remove this, I will do so. This is just my version that I use for my private forums.

Information shown:
1) Page loading times
2) Number of Queries
3) Server Loads
4) Number of Any Uncached Templates
5) Name of Uncached Templates (NEW!)

By default only an Admin (usergroup 6) can see it. Feel free to modify this bit.

It's very easy to install.

Open includes/functions.php:

Find:

PHP Code:


			
// ####################################################################
    // temporary code
    global $_TEMPLATEQUERIES, $tempusagecache, $DEVDEBUG, $_SERVER, $debug;

UNDERNEATH, ADD:

Version 1.2 - more optimized but requires /proc on your server - try this, if server loads don't show up use Version 1.02 below

PHP Code:


			
// Microstats hack
if ($bbuserinfo[usergroupid]==6) {
                $pageendtime = microtime(); 
                $starttime = explode(' ', $pagestarttime); 
                $endtime = explode(' ', $pageendtime); 
                $totaltime = vb_number_format($endtime[0] - $starttime[0] + $endtime[1] - $starttime[1], 5); 
                $loadavg = @file_get_contents("/proc/loadavg"); 
                if ($loadavg) { 
                        $regs = explode(" ",$loadavg); 
                        $serverload=' [Server Loads: <b>'.$regs[0].'</b> '.$regs[1].' : '.$regs[2].']'; 
                } 
                $debughtml = "<center><span class=\"smallfont\">Page generated in <b>$totaltime</b> seconds with <b>$query_count</b> queries" . iif($_TEMPLATEQUERIES, " (<b>" . sizeof($_TEMPLATEQUERIES) . "</b> queries for uncached templates)", '') . "$serverload</span></center>"; 
    ksort($tempusagecache);
    foreach ($tempusagecache AS $tempname => $times)
    {
    if ($_TEMPLATEQUERIES["$tempname"]) $debughtml .= "<center><span class=\"smallfont\">Uncached templates: <font color=\"red\"><b>$tempname</b></font> ($times)</span></center>";
    }
                $vartext = str_replace('</body>', "$debughtml\n</body>", $vartext); 
 
}
//Microstats Hack

Version 1.02 - Use this if Version 1.1 doesn't work for you.

PHP Code:


			
// Microstats hack 
if ($bbuserinfo[usergroupid]==6) {
$pageendtime = microtime(); 
$starttime = explode(' ', $pagestarttime); 
$endtime = explode(' ', $pageendtime); 
$totaltime = vb_number_format($endtime[0] - $starttime[0] + $endtime[1] - $starttime[1], 5); 
if ($stats=@exec('uptime')) { 
     preg_match('/averages?: ([0-9\.]+),[\s]+([0-9\.]+),[\s]+([0-9\.]+)/',$stats,$regs); 
     $serverload=' [Server Loads: <b>'.$regs[1].'</b> ? '.$regs[2].' : '.$regs[3].']'; 
     } 
$debughtml = "<center><span class=\"smallfont\">Page generated in <b>$totaltime</b> seconds with <b>$query_count</b> queries" . iif($_TEMPLATEQUERIES, " (<b>" . sizeof($_TEMPLATEQUERIES) . "</b> queries for uncached templates)", '') . "$serverload</span>"; 
$vartext = str_replace('</body>', "$debughtml\n</body>", $vartext); 
    ksort($tempusagecache);
    foreach ($tempusagecache AS $tempname => $times)
    {
    if ($_TEMPLATEQUERIES["$tempname"]) $debughtml .= "<center><span class=\"smallfont\">Uncached templates: <font color=\"red\"><b>$tempname</b></font> ($times)</span></center>";
    }
}
//Microstats Hack

Done! As simple as that. No need to enable debug mode.

If you want only yourself to have this information, change:
if ($bbuserinfo[usergroupid]==6) {
to
if ($bbuserinfo[userid]==1) {

And replace 1 with your userid.

To let everyone see it, remove that line, and the last } of the code above.

Below is a screenshot of how my forumhome microstats look.

EDIT: Thanks to kmike, I optimized the code. This should lessen the load when checking the server loads slightly.

Version 1.2 and 1.02 now has added code to show NAMES OF UNCACHED TEMPLATES!

Do you have access to server's shell? If so, what's output of "ls -l /proc/loadavg" and
"ls -ld /proc" ?
Anyway, you might want to revert to previous version of the hack for the time being...

Jolten · #**133** 04-22-2004, 03:21 AM

/me clicks install. Thanks Erwin.

I may add a feature to this hack so that uncached templates show up with names.

that will be great!

by the way what kind of problem does uncached templates gives? increase server load?

Each vb3 page is getting all "cached" templates in a batch, in one SQL query. Every uncached template needs separate query to run, thus increasing load on SQL server.

To find out what templates are uncached, one have to run the script in debug mode. Of course tt could be done simply by putting $debug=1; at the beginning of the script, but you don't want to scare your users, do you?

So you can install one of the following hacks to restrict debug mode to certain users/groups/IPs:

https://vborg.vbsupport.ru/showthread.php?t=59605
https://vborg.vbsupport.ru/showthread.php?t=61242

After installation, you'll have a table of template usage at the bottom of debugged page, with uncached templates highlighted.
To cache template simply edit debugged script and add template name to globaltemplates array which is usually defined at the very top of the script.

here's my output

root@xxx [~]# ls -l /proc/loadavg
-r--r--r-- 1 root root 0 Apr 22 20:20 /proc/loadavg
root@xxx [~]# ls -ld /proc
dr-xr-xr-x 286 root root 0 Apr 22 07:06 /proc/

i written my TOS page , http://forums.keeptouch.net/tos.php using this code :

Code:

<?php

  $globaltemplates = array(
	'navbar',
	'tos'
  );

  require_once('./global.php');

  eval('$navbar = "' . fetch_template('navbar') . '";');
  eval('print_output("' . fetch_template('tos') . '");');

?>

Previously I did not add :

Code:

$globaltemplates = array(
	'navbar',
	'tos'
  );

so it appears as 1 uncached template but after i added the above code, it does not appears anymore. Am I on the right track?

Hmm, not sure what's going on here. Do you have safe mode enabled, by chance?
What is output of this script:

PHP Code:


			
<?php

echo "file_get_contents: ".function_exists(file_get_contents)."<br>";

echo "safe_mode: ".ini_get(safe_mode)."<br>";

?>

As to templates caching, you've got it absolutely right.

nope, safe mode definitely not on

my output of this script is

file_get_contents: 1
safe_mode:

kmike · #**141** 04-23-2004, 03:57 AM

Very weird.
Ok, what does "cat /proc/loadavg" show when run in the command line?
And since we're so deep in testing, what's output of this php script:

PHP Code:


			
<?php

echo file_get_contents("/proc/loadavg");

?>
