Hi Stephane,


Thanks for posting in the community!
From your description, you're looking for some good means to stress test a
web application. Also, you're wanting some infos on using the IIS log
files, yes?
If there is anything I misunderstood, please feel free to let me know.

Based on my research, there're many web stress tools all over. And MS also
provided some good web stress tools. I'm not sure whether you've the
"Application Center Test" installed, this is a good test tools integrated
with Visual Studio Enterprise version. Here is the description in MDSN:

#Microsoft Application Center Test 1.0, Visual Studio .NET Edition
http://msdn.microsoft.com/library/en-us/act/htm/actml_main.asp?frame=true

Also, there are some other light weight web stress tools there:

#MS Web Application Stress Tool

?frame=true

#Using WCAT to Stress-Test IIS
http://msdn.microsoft.com/library/en-us/dniis/html/usingWCAT.asp?frame=true

You may have a view to see whether they're suitable for you.
In addtion, as for the IIS logs, here are some tech articles discusing on
them:

#IIS Logging

Hope they're also helpful!

we are curently using MS application center test tool with Visaul Studio
.NET 2003; and its great, but my question is the following (sorry for
not being lcear the first time):
- how can i use the IIS logs from the live site as scripts to run
against the test site using MS application center test tool (or other
tool) ?

so instead of creating or recording scripts using application center
test; i want a tool that can read the IIS logs of a site, and play it
back.

i assume this is a common procedure in load testing


thanks
stephane

Hi stephane,


Thanks for your followup. As for the logs info of the IIS, currently there
seems not any tools which can directly used to read IIS log data. However
,the IIS log file has some certain Data Format so that we can manually
retireve them according to these formats, for detailed information on the
IIS log File format, you may view the following reference in MSDN:

#IIS Log File Formats
http://msdn.microsoft.com/library/en-us/iissdk/iis/iiis_log_file_formats.asp
?frame=true

In addition, there is a tool named IDC which can be used to display log
data from the IIS ODBC logs in an HTML page.

#IIS Internet Database Connector

Please have a check on the above items to see whether they're helpful!
