Ormolu : generating runtime monitors from alloy models

[摘要] This thesis presents Ormolu, a runtime monitor used for monitoring distributed systems. Given an Alloy model, Ormolu generates a database schema and translates the constraints of the model to queries over the database. The translation preserves the semantics of Alloy, especially in regards to its type system. Ormolu allows domain specific knowledge to be expressed in Alloy, where it can be checked and verified. The same model can then be used to check if the constraints of the model are still satisfied at runtime. The feasibility of Ormolu is examined in the domain of air traffic control at a local airport, using data provided by the Tower Flight Data Manager developed by Lincoln Laboratory.
