[EMAIL PROTECTED] Session Count Question From a Newbie

2006-05-05 Thread Stuart, Ed
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?

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

May not be exactly what you're looking for, but try:

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.
