Cheshire Cat Computing

Background:
I installed the MRTG + Perl and work successful and smooth. The PIX525 can read all eth port traffic on indexmaker generated web page.
Because I want to keep all traffic log and generate a report on a specific time zone, that's why I want to install the powerful RRDTOOL running with MRTG. I am not sure the installation procedure is correct

1) I downloaded the RRDTool and extract to a local hard drive and run "ppm install rrds.ppd" under c:\rrdtool\perl-shared directory

2) Copy each .exe file (rrdcheckbounds.exe, rrd_cgi.exe, rrd_stats.exe and rrdtool.exe) to my c:\mrtg\bin
c:\rrdtool\src\bounds_release
c:\rrdtool\src\rrd_cgi_Release
c:\rrdtool\src\stats_releasese
c:\rrdtool\src\tool_release

3) Use the cfgmaker to generate a PIX525.cfg again and try to collect all log data within 1 min.
### Global Config Options
Workdir: c:\RRDtool
PathAdd: C:\mrtg\bin
LibAdd: C:\rrdtool\perl-shared
Logdir: c:\mrtghtml
logformat: rrdtool
RunAsDaemon: Yes
Interval: 1

Problem:
Found out the rrd file was generated after I run the "perl mrtg PIX525.cfg", but it keep going with 203k byte of the file size even I was waiting for all night

The *.rrd file found on c:\mrtghtml directory
10.10.36.1_1.rrd 203kB
10.10.36.1_2.rrd 203kB
10.10.36.1_3.rrd 203kB
10.10.36.1_4.rrd 203kB
10.10.36.1_5.rrd 203kB
10.10.36.1_6.rrd 203kB

I tried to use the rrdtool info command to show one of rrd log file, it works and seems normal
C:\mrtg\bin>rrdtool info c:\mrtghtml\10.10.31.1_1.rrd

Question:
Why the RRD log file is not updated in my environment, am I missing something or my RRD file path is incorrect? Anybody can help me please. Thanks
