The use of parallel architectures, not only in scientific and corporate, but also in domestic systems, made the multithread programming more popular, forcing programmers to face the problems related to concurrency control. The transactional memory was proposed as a way for easing parallel program development, providing the programmer the possibility to only mark the sections of code that are to be executed in an atomic and isolated way. In this work, it’s proposed a Linux kernel modification that is able to monitor transactional memory events like started, aborted and commited transactions, making it possible to observe the behaviour of a program that uses transactional memory without the need to interrupt its execution and with low overhead in user time. The information produced by this monitoring system is published in a virtual file system to make them available for analysis and monitoring tools that do not have access permissions to access them directly, helping the developer to decide whether some transactional memory aproach is better than other or if the use of transactional memory is advantageous over the use of classical mechanisms of concurrency control.
