Bisdw is a simple ETL tool that we developed for monitoring use case that demanded us to retrieve data from different source and put it into a local database. As a tool it can be used independent of Bischeck. Most of the ETL logic is provided by the Scriptella project. What we have added are functionality for scheduling, FTP integration, init scripts, etc.

You can download Bisdw from gforge.ingby.com. Documentation is available here.
