When Is An Access Posted in Apache's Access Log?

[Steven W. Illgen]

We are having a problem where there are numerous threaded HTTP calls being made through our Apache server which, when seen with http://localhost/server-status, have a "W" (Awaiting Reply) status and remain in this state for a very long time. (In some cases, we had to restart Apache to clear these.) When looking at Apache's access log, it appears that some of these requests are not listed.

There is more to this than what I have posted, so this is not a question about the lockups themselves. Rather, my question is, when does Apache post an "access" to the access log? In other words, does a call need to receive a successful reply from the appropriate module or application before the post is made? I need to know this so I can determine whether how to best interpret the data in our access logs.

Thank you,

Steve Illgen

Thank you for the reply and the link. From what I am able to gather from this link and from HP Support, ALL requests are logged; however, if there is a error in the request, an error code is generated and stored along witht the request. I will need to look at the error codes and also configure the CustomLog directive to provide more detailed entries to help us debug this problem.
