Hello Experts...

I have a IIS Load Balance Farm with 2 Servers. 3.000 Sites in cluster.

Whats the best way to get Visit Stats for both servers in one location ?

In other words i need to generate html reports in one location with the combined logs.

Any clues ?

We are using AWStats to analyze and merge our logfiles:
http://awstats.sourceforge.net/

You habe to copy all logs to one directory (rename them if you have equal named files on each server) and the run AWStats with merge enabled in configuration:

PROBLEM:
How can I update my statistics when i use a load balancing system that split my logs ?

SOLUTION:
First solution is to merge all split log files resulted from all your load balanced servers into one. For this, you can use the logresolvemerge tool provided with AWStats :
logresolvemerge.pl file1.log file2.log ... filen.log > newfiletoprocess.log
And setup the LogFile parameter in your config file to process the newfiletoprocess.log file or use the -LogFile command line option to overwrite LogFile value.

As an other solution, if you miss disk space, or to save time, you can ask logresolvemerge to merge log files on the fly during the AWStats update process. For this, you can use the following syntax in your AWStats config file:
LogFile="/pathto/logresolvemerge.pl file*.log |"

Good hint, but i think that it will be very dificult due to a lot o Websites.

I was thinking about a log analizer that can use two log sources, one UCN and one Local.
