Reminder
• Slides and 2-page writeup due by next Tuesday
• Feb 21: 3-minute talk
2
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
3
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
4
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?
5
Discussion
• Experiments
• Premises (Section 2.1)
• Future work
