modules_logger

Inspired by Jeff Layton's article on logging usage of environment modules, http://hpc.admin-magazine.com/Articles/Gathering-Data-on-Environment-Modules, and by Harvard's modules-usage project, https://github.com/fasrc/module-usage. Also, I wanted to learn MongoDB, and data persistence for this project was a good excuse. :)

Logs all "module" commands, and keeps a running tally of how many times each module is loaded by a given user. Uses MongoDB for persistence. Requires pymongo.

To build and install an RPM (preferred)

0. To build the man pages into the RPM, add the following line to ~/.rpmmacros: %__os_install_post %{nil}
1. python setup.py bdist_rpm
2. sudo yum localinstall dist/modules-logger-0.1-1.noarch.rpm

To install by hand:

• Install and start MongoDB, and install pymongo. The relevant packages are in the EPEL repository for EL6: installing "mongodb", "mongodb-server", and "pymongo" should be sufficient. The default configuration binds to 127.0.0.1, so you may want to adjust the configuration to expose to other cluster nodes.
• Put modules_logger and modules_usage into the PATH on your nodes (/usr/local/bin, for example)
• Put modules_logger.conf into /etc/, and edit the config appropriately.
• Replace /etc/profile.d/modules.sh with the modules.sh.logger provided here.

TODO:

• Add support for csh/tcsh
• Add additional reporting functions besides "how many times user X loaded each module"
• Detect failed loads?
