Aid Diagnosis?
System assists human in diagnosing problems
- Root-cause analysis to suggest possible failure points
- Track resource dependencies of all requests
- Correlate symptomatic requests with component dependency model to isolate culprit components
- “health” reporting to detect failed/failing components
- Failure information, self-test results propagated upwards
- Don’t rely on things connected according to plans
- Example: Discovery of network, power topology
Not a major focus of Berkeley or Stanford ROC projects
