To refresh, we run two websites for a client and we run a stats report every month to show the combined stats for the two sites using Analog 5.1

combined.cfg
-------------------------------------------------------------------------
---------------------------
# to combine the stats for ALL PAGES of two sites, each on different #servers.

LOGFORMAT COMMON
LOGFORMAT COMBINED
LOGFILE /usr/local/etc/httpd/logs/access_log.yyyymmdd
# including all daily log files to last day of month

LOGFILE /usr/local/etc/httpd/logs/access_log-otherdomain.yyyymm

# minimum 1 request before inclusion in output
REQFLOOR 1r

# don't report "possible log file overlap"
WARNINGS -L

OUTFILE /usr/local/etc/httpd/htdocs/stats/combinedyyyymm.html
-------------------------------------------------------------------------
---------------------------

We also run a stats report each month showing the combined stats for the HOMEPAGES ONLY of each site.

This report shows a total successful requests for pages and the request report shows 'Listing files with at least 20 requests' for SITE1 only

combhomeonly.cfg
-------------------------------------------------------------------------
-------------------------------
# to combine the stats for the home pages only of two sites each on #different servers.

LOGFORMAT COMMON
LOGFORMAT COMBINED
LOGFILE /usr/local/etc/httpd/logs/access_log.yyymmmdd
# including all daily log files to last day of month

LOGFILE /usr/local/etc/httpd/logs/access_log-otherdomain.yyyymm

# don't report "possible log file overlap"
WARNINGS -L

# only include home page requests

FILEINCLUDE http://www.otherdomain.com/

OKAY...

The following visitor figures are extracted from the stats since 200501 after the above config files have been processed.

SITE1 and SITE2 figures are for the homepages only taken from the
output file:- htdocs/stats/combinedyyyymm.html

The COMBINED visitor figure is again for the homepages only taken from the output file:- htdocs/stats/combhomeonlyyyyymm.html

Although the reports are run at the same time the figures for Site2 on the two reports never tally but they have always been within 95% - 97%.

I noticed yesterday that Site2 log files are created 6 hours earlier but I cannot see that making much of a difference... 6 hours out of 30 days does not equate to up to 5% difference... anyway not really wanting to concentrate on that.

SITE1 figures always tallied in the two reports until the 200505 reports were run.

DATE      SITE1    SITE2       COMBINED     % Diff.
200501    1854       762          2533 (1854)     96.38
200502    1648       897          2444 (1648)     96.03
200503    1366       835          2096 (1366)     95.23
200504    1481     1128          2535 (1481)     97.16

This is where it becomes even more convoluted... sorry.

outfile stats/combhomeonlyyyyymm.html:- reports run for 200505 to 200507 still shows a total successful requests for pages but the request report is empty.

outfile stats/combinedyyyymm.html:- reports run for 200505 to 200507 seem to be reporting normally.

HOWEVER!

If I take as red the SITE1 figures and add the SITE2 figures there is now a much bigger difference to the COMBINED figures... let me demonstrate:

DATE      SITE1    SITE2       COMBINED     % Diff.
200505    1651       1109         2508              90.87
200506    1933       1057         2705              90.47
200507    1545       1091         2343              88.88

Somewhere, something is just not right and I'm nearly bald!

Please believe me Mr Turner... we have not changed our processes at all that would cause a change since May2005 to date. Analog has been used on these servers for seven to eight years now... with no previous problem.
