Hi Andrej,
the concept of a transaction is defined in the Application Response
Measurement (ARM) standard. The mod_arm4 implements an interface between
the Apache httpd and the ARM standard. ARM has the capability to
correlate transactions in distributed environments and with an ARM
enabled HTTP client you get all what you want.
Also we at MyARM are working on a firefox extension which will measure
any HTTP request sent by the browser and these transactions will be
correlated to any HTTP request measured in the apache httpd using the
mod_arm4 module.
Regards,
Stefan

Hi,
I am looking for a way to deduct the concept of a "transaction" from
the Apache log. What I mean is that I want to group HTTP requests that
are sent by one particular client, for example when a user clicks a
link in the browser. Then I want to be able to group all the HTTP
requests that are the result of that one click (only taking account
for requests that are going to our servers).
Assuming that both client and server have the KeepAlive enabled, I
though that maybe a custom Apache log-module could write the
connection ID (if such a thing exists) to the log in order to
distinguish different clients. Moreover, assuming that users wait for
at least 1 second between clicks, I should be able to deduct
transactions by grouping them on timestamps that fall within a second.
The scheme with the connection ID, can it work, or am I misjudging
something completely? Are there alternatives?
Thank you,
Andrej
