The system works, yet there remains much tweaking to do.
Large functionality changes should probably get some discussion on the mailing list before being submitted. A fictional Dr. Sherbert is writing a handler to display web statistics (information present in /var/log/httpd/access.log). Here is a list of e-mails and commands which take place. Dr. Sherbert e-mails the list with his idea sherbert %> mail lon-capa@hobbes.lite.msu.edu Hi, I want to create a handler to show web statistics (hits per hour, IP addresses, most popular URLs, hits per day, etc). This would provide data I can show the administration as well as helping me better monitor how adequately my server cluster is performing. I plan on calling this handler lonapachestat.pm, associating with apachestat, and available only to those with roles (see roles.tab and rolesplain.tab) of "gan=generating anonymous statistics". I would make appropriate changes to /etc/httpd/conf/srm.conf -Bert Two others respond on the mailing list. gwynne %> mail lon-capa@hobbes.lite.msu.edu Bert, I like that idea, but don't you think that this is better handled as a batch-cron job? Why not have these statistics compiled every day? I think SOURCE="loncom/cron/loncapa" TARGET="etc/cron.d/loncapa" handles this. Also, I assume you mean associating with the location http://MACHINENAME/adm/lonapachestat. Gwynne godfried %> mail lon-capa@hobbes.lite.msu.edu Bert, This would be of immense help to some questions I have. I want to be able to "play-back" what each user session is doing for my course. Also, if a student e-mails me, I want to be able to see where in the course sequence the student was working. I would need the statistics calculated dynamically as opposed to a batch process. Godfried After more discussion, Dr. Sherbert's idea is accepted. |
PATCHING /etc/httpd/conf/srm.conf
submit patches to albertel@msu.edu
Dr. Sherbert wants to alter the web server configuration so that whenever http://MACHINENAME/apachestat is requested, the lonapachestat.pm handler is called. To do this, he needs to alter srm.conf. After setting up CVS and checking out LON-CAPA (cvs co loncapa), he needs to find srm.conf in the CVS source repository. [sherbert@morphy1 loncapa]$ find . -type f | grep srm.conf ./loncom/srm.conf [sherbert@morphy1 loncapa]$ Dr. Sherbert sees the following section of code in srm.conf. # -------------------------------------------------------------- Admin Programs <Location /adm/roles> PerlAccessHandler Apache::lonacc SetHandler perl-script PerlHandler Apache::lonroles ErrorDocument 403 /adm/login ErrorDocument 500 /adm/errorhandler </Location> <Location /adm/login> SetHandler perl-script PerlHandler Apache::lonlogin </Location> <Location /adm/logout> PerlAccessHandler Apache::lonacc SetHandler perl-script PerlHandler Apache::lonlogout ErrorDocument 403 /adm/login </Location> Dr. Sherbert then adds in his handler. # -------------------------------------------------------------- Admin Programs <Location /adm/apachestat> PerlAccessHandler Apache::lonacc SetHandler perl-script PerlHandler Apache::lonapachestat ErrorDocument 403 /adm/login ErrorDocument 500 /adm/errorhandler </Location> <Location /adm/roles> PerlAccessHandler Apache::lonacc SetHandler perl-script PerlHandler Apache::lonroles ErrorDocument 403 /adm/login ErrorDocument 500 /adm/errorhandler </Location> <Location /adm/login> SetHandler perl-script PerlHandler Apache::lonlogin </Location> <Location /adm/logout> PerlAccessHandler Apache::lonacc SetHandler perl-script PerlHandler Apache::lonlogout ErrorDocument 403 /adm/login </Location> Dr. Sherbert then creates a unified diff format of his changes against the HEAD (current) release.
