[users@httpd] Session Count Question From a Newbie
Hello all;
I new to the administration of an Apache web server and am looking for a
way to see how many clients are connected to the web server. We're
running Apache 2.0.46 on Red Hat AS 4. Netstat gives me connection info,
but shows multiple connections for the clients. How can I report how
many clients are connected to the web server at a given time?

There is also mod_status's server-status handler. But it will also
give "multiple connections for the clients". That is because browsers
make multiple connections to the server when downloading all the
objects from a page. The only way to tell what connections come from
a particular user is to track sessions using cookies or similar
techniques.

Just a quick sanity check:
You do understand that there is a big difference between a session
(referenced in your subject) and a connection (referenced in your
message body)?
And you do understand that a connection lasts only for a single
request/response, i.e. less than a second? An active user is constantly
making new connections (for each request).
A session, by definition, lasts over a series of requests/responses. But
it is not part of the HTTP protocol and so must be managed (and counted)
programatically via PHP, perl, autc.
Moreover, there isn't an exact way to tell when a session has ended.
They are usually programmed to time out after a certain number of
minutes of inactivity.
Websites that report the "number of users currently online" probably
cheat a bit by counting either the sessions or distinct IP connections
made over the last five or ten minutes.

Hi,
To see live connections, you can use the following:
# watch tail /var/log/httpd/access_log
To report on connections over time, you might want to use something like
webalizer
Hope that helps,
Rick
