ABSTRACT = {Self-diagnosis is a fundamental capability of self-adaptive
systems. In order to recover from faults, systems need
to know which part is responsible for the incorrect behavior. In
previous work we showed how to apply a design-time diagnosis
technique at run time to identify faults at the architectural level
of a system. Our contributions address three major shortcomings
of our previous work: 1) we present an expressive, hierarchical
language to describe system behavior that can be used to
diagnose when a system is behaving different to expectation; the
hierarchical language facilitates mapping low level system events
to architecture level events; 2) we provide an automatic way to
determine how much data to collect before an accurate diagnosis
can be produced; and 3) we develop a technique that allows the
detection of correlated faults between components. Our results
are validated experimentally by injecting several failures into a
system and accurately diagnosing them using our algorithm.},
