Minimal Observability for Transactional Hierarchical Services

  title={Minimal Observability for Transactional Hierarchical Services},
  author={Debmalya Biswas and Blaise Genest},
For complex services, logging is an integral part of many middleware aspects, especially, transactions and monitor ing. In the event of a failure, the log allows us to deduce the cause of failure (diagnosis), recover by compensating the logged actions (atomicity), etc. However, for heterogeneo us services, logging all the actions is often impracticable du to privacy/security constraints. Also, logging is expensi ve in terms of both time and space. Thus, we are interested in determining the… CONTINUE READING
