[LON-CAPA-admin] autoenroll.log

Hi Mark,

The Perl script you describe is essentially what I see as the most straightforward way to deal with the "noisy" log and creating something like this is exactly what I had in mind. 

I look in /home/httpd/lonUsers/bsu/1/Q/7/1Q746312661a84458bsul1 and find a number of .db files, e.g., bsu_1Q746312661a84458bsul1.db, which, according to "file bsu_1Q746312661a84458bsul1.db" looks like "GNU dbm 1.x or ndbm database, little endian", i.e., it is a binary file that is probably a GNU dbm file. I haven't used GNU dbm files before, but I'm looking up some docs to see what I can do to see what's in them.

Thanks,
Paul

Paul,

If you're looking at doing this outside of LON-CAPA proper, the following might be useful.

A course has a directory under lonUsers. You can go to (I'm not logged in right now so this is
approximate)   /home/httpd/lonUsers/bsu/1/Q/7/1Q746312661a84458bsul1   and look for
a .db file that contains the course name. You could create a perl script that runs through the autoenrollment log filters out the lines of historical courses, translates the course ID for the current courses, and then hands out the rest of the information.

As always, the caveat is to be careful when poking around in lonUsers and other system places by 'hand'.

Hope this helps!
Mark

It doesn't have to be something within LON-CAPA proper, in fact, I'd prefer something that could generate a plain text file. If anyone has a clue for me on constructing a MySQL query against the database so that I can extract that information, I could use that.  Basically, I'd like to filter out the past courses from autoenroll.log so I can see what is happening to the current courses without all the noise from irrelevant courses. I can do that in many different ways, I'm sure, but it strikes me that simply generating a list of what all the courses in the database are/have been (particularly by "affiliate" id, which is all the course identification that is in the log) would give me a relatively straightforward start on such a filter so I can say:
