Episode notes
Observability as a System Property
- Observability is a property of complex systems, like scalability or performance.
- It improves by adding metrics, educating teams, and connecting data sources.
Disconnected Data Sources
- Many engineers capture data multiple times per request for different tools (dashboards, logs, traces).
- These tools are disconnected, except for the engineer manually connecting them.
Observability 2.0: Single Source of Truth
- Observability 2.0 tools use a single source of truth: structured data blobs (canonical logs or traces).
- From this, derive SLOs, metrics, dashboards, logs, and traces, offering more powerful analysis.
