Released: LogBook, An Open Source AIR based Flex Logging Application


As promised, today we are formally releasing LogBook, our internally developed tool for logging events from Flex (and coming very soon, pure Flash AS2/AS3) applications. For the uninitiated, logging is the process of recording and storing information about events in your application. The functionality is similar to the trace command, but a lot more robust. Logging combined with a strong log viewer like LogBook gives you a much deeper understanding of the state of your application.

Some quick notes on LogBook:

1) LogBook is being released under the MIT open source license.
2) A detailed post on its features and how to use it is here at the CIM Flash Team Blog.
3) The code for LogBook is being hosted at
4) We have also set up a Google group for logbook that we can use to discuss features that we should add in upcoming releases and bugfixes/patches.
5) The installer can be found in the downloads section there.
6) LogBook runs on the AIR beta 3 runtime.

At CIM we already have a list of features we are going to release in the next build. But of course if you have any feature you would like to request, please drop us a mail at We are really hoping LogBook 1.2 is the first step towards a robust Flex/Flash development/debugging toolset.

Happy debugging :).
