  1. CompSci 296.2 Self-Managing Systems Shivnath Babu

  2. Reminder • Slides and 2-page writeup due by next Tuesday • Feb 21: 3-minute talk

  3. Correlating Instrumentation Data to System States • Collect performance data, with SLA violations • Build models: Tree-Augmented Bayesian Networks • Model correlates system metrics to SLA violations • Simplifies problem diagnosis

  4. Correlating Instrumentation Data to System States • Collecting performance data • Recording SLA (SLO) violations • Mapping to a classification problem • Balanced accuracy • TANs • Finding the best TAN • Experiments

  5. Discussion • Strong points • Thorough • Formalize problem • Clarify assumptions • Detailed experiments • Discussion of future work • Weak points • Sometime descriptions are fuzzy/missing • Ex: Building TAN, Using TAN, Interpretability, Graphs • Realistic experiments?

  6. Discussion • Experiments • Premises (Section 2.1) • Future work
