Memory vs Total memory usage (incl. children)

[Lapa Vikentsi]

Hello, all

I use  monit 5.2.3 on my CentOS 5.4 system to monitor apache server
and many other processes.

Main question:
Why Monit display different memory consumption on System and Proccess
status on http page?
I try search similar questions in maillist arhcive but it have only
half answer to my question
 http://lists.nongnu.org/archive/html/monit-general/2008-05/msg00052.html

Below I explain details. My http page looks like

Monit Service Manager
---------------------------------
System Status Load CPU Memory Swap
                       893436 kB
---------------------------------
Process Status Uptime CPU     Memory
...
httpd                         22748 kB
----------------------------------

Total sum of all processes is 402276 kB and system is  893436 kB

>From main page I can quickly found which process consume more memory.
But I need  go over all processes to find one with largest
consumption.

I go to link http://localhost/monit/httpd and view following

httpd   running 7d 9h 0m        0.0%    2.1% [22748 kB]
Memory usage    2.1% [22748kB]k
Total memory usage (incl. children)     14.0% [147508kB]

Why on main page monit show Memory usage and not Total memory usage
(incl. children) ?

I look in code and found that output differ on one line of code
     out_print(res,
          "<td align=\"right\"><font%s>%.1f%% [%ld&nbsp;kB]</font></td></tr>",
          (s->error & Event_Resource)?" color='#ff0000'":"",

-          s->inf->priv.process.mem_percent/10.0,
s->inf->priv.process.mem_kbyte);

+          s->inf->priv.process.total_mem_percent/10.0,
s->inf->priv.process.total_mem_kbyte);

But I am not developer and can't  predict effect of such changes.
Please, tell thoughts about such "improvement".
