9. Traces
   The “new cool kid on the block” pillar
   Root cause isolation, and more
   End-to-end monitoring
   Distributed (hard to bill for usage)
   Capture causality (DAG)
   Workflow centric
   Request-scoped logs

10. Events
    The misunderstood pillar
    Lower volume
    Strong identity
    High reliability requirement
    Shape: structured logs
    Change events
    Everything is an “event”

11. Profiles
    The geek pillar
    Aggregatable
    Large data volumes
    No instrumentation required
    Power user tool
    Lower usage
    Know when you see it

12. Exceptions
    The forgotten pillar
    Custom UI
    Special processing pipeline
    Aggregatable *

13. Conclusion
    Don’t take it seriously
    There are more than “3 pillars”
    The term TEMPLE is awesome
    The boundaries are diffuse
    Pillars ≠ observability, just data
