In this talk, Christopher Judd shows us how observability is done with Opentelemetry and how to face the challenge of distributed tracing.
1) short name: o11y
2) idea: like a doctor checking external signals to understand internal issues
3) Twitter pillars: monitoring, alerting/Visualization, Distributed Systems Tracing Infrastructure, Log Aggregation/Analytics
4) telemetry definition: get remotely information from equipment
5) opentelemetry
- is not a replacement ❌🔃 for your monitoring tools
- is 100% free 🆓 and open source 🔓
- provides you with metrics, distributed traces, and logs
- is kind of JDBC as it connects to observability collectors
6) Distributed tracing is done with a correlation id
7) In the demo, I saw the outputs in the spring boot logs, then in a GUI done by Zipkin (which looks like the network tab of the chrome dev console with the horizontal bars)
