HI Andrew,
good idea, but why you can contribute a code from Harish Prabandham
([EMAIL PROTECTED]).
We can only accept contributions from orignal author and with Apache
2 license included!
I seems that this only work with java 5 and the code is designed for
JIO HTTP tomcat 5.5.
Open a bug report, then we can discuss your contribution.
Regards,
Peter

Hello,
I want to contribute a custom SocketFactory allowing to analyze the
utilization of acceptConnection attribute of a Connector. In a
properly configured production system, there should be rare
situations where connections wait for a worker thread to be
handled. Our client complained on high latency of web requests, but
the measurement on servlet did not show high latency. So we wanted
to know the number of connections which wait in socket backlog and
were not accepted yet.
I solved this problem by writing a custom SocketFactory, which
accepts connections immediately and puts it in my queue until a
call to accept() will take them. So the number of waiting
connections can be monitored via JMX.
To activate this factory, the declaration of the corresponding
Connector in server.xml should be changed like in the following
example.
<Connector port="8080" maxHttpHeaderSize="8192"
maxThreads="10" minSpareThreads="5" maxSpareThreads="7"
enableLookups="false" redirectPort="8443"
acceptCount="10"
connectionTimeout="2000" disableUploadTimeout="true"
socketFactory="org.apache.tomcat.util.net.BacklogMeasuringServerSocket
Factory"/>
No changes in existing classes are required.
Please review the code in the attachment.
Andrew Skiba.
