event and data logging

Working with Kolab has kept me busy on numerous fronts since I joined near the end of last year. There is the upcoming Kolab Summit, refreshing Kolab Systems' messaging, helping with progress around Kolab Now, collaborating on development process improvement, working on the design and implementation of Akonadi Next, the occassional sales engineering call ... so I've been kept busy, and been able to work with a number of excellent people in the process both in Kolab Systems and the Kolab community at large.

While much of that list of topics doesn't immediately bring "writing code" to mind, I have had the opportunity to work on a few "hands on keyboard, writing code" projects. Thankfully. ;)

One of the more interesting ones, at least to me, has been work on an emerging data loss prevention and audit trail system for Kolab called Bonnie. It's one of those things that companies and governmental users tend to really want, but which is fairly non-trivial to achieve.

There are, in broad strokes, three main steps in such a system:

  1. Capturing and recording events
  2. Storing data payloads associated with those events
  3. Recreating histories which can be reviewed and even restored from

I've been primarily working on the first two items, while a colleague has been focusing on the third point. Since each of these points is a relatively large topic on their own, I'll be covering each individually in subsequent blog entries.

We'll start in the next blog entry by looking at event capture and storage, why it is necessary (as opposed to simply combing through system logs, e.g.) and what we gain from it. I'll also introduce one of the Bonnie components, Egara, which is responsible for this set of functionality.
