Abstract--Traditionally, performance has been the most im-
portant metrics when evaluating a system. However, in the last
decades industry and academia have been paying increasing
attention to another metric to evaluate servers: availability. A
web server may serve many users when running, but if it is
out of service too much time, it becomes useless and expensive.
The industry has adopted several techniques to improve system
availability, yet crashes still happen. In this paper, we propose
a new framework to predict time-to-failure when the system is
