It is not our goal, either, to demonstrate complete use cases for SALSA. For example, while we demonstrate one application of SALSA for failure diagnosis, we do not claim that this failure-diagnosis technique is com- plete nor perfect. It is merely illustrative of the types of useful analyses that SALSA can support. Finally, while we can support an online version of SALSA that would analyze log entries generated as the system executes, the goal of this paper is not to describe such an online log-analysis technique or its runtime over- heads. In this paper, we use SALSA in an offline manner, to analyze logs incrementally
