Re: Understanding the APACHE 1.3 process model

You could just ask apache's server-status page. From there you can  

also get more detailed information such as which are connected and  

sending or receiving data as well as those connected but not doing  

anything.

Thanks Sander.

Therefore, this makes me think that I can't actually use netstat to

'measure' the 'number of concurrently connected clients'? Is this a  

fair

assumption?

Cheers, Craig

you likely have 23 established connections using server processes and
an additional number of server processes available to handle new
connections. Apache keeps some number of processes available so that
it doesn't have to fork the process at the time the request is made,
but instead has the process ready to go. There are httpd.conf
parameters to specify the minimum and maximum of these to keep
available.

See MinSpareServers, MaxSpareServers.

The TIME_WAIT, FIN_WAIT_1, FIN_WAIT_2 and LAST_ACK sockets should  

not be

attached to httpd children.

httpd doesn't deal with the TCP layer, it deals with socket file
descriptors.
