Current perception about observability Where When What Tools + Processes + People Tools + Processes + People Tools + Processes + People Logging Metrics Tracing

“…this seems like calling ‘gasoline, motor oil, and tires’ the 3 pillars of F1 racing. It is not wrong, precisely, but…” Josh Berkus Kubernetes Community Manager, Red Hat

Observability redefined: pipes (not pillars) Request-scoped metrics Metrics Aggregatable Tracing Aggregatable events Request Scoped Logging Events Request-scoped events Request-scoped contextual View

Overview about OpenTelemetry https://opentelemetry.io

• Based on the projects OpenTracing and OpenCensus • Open source CNCF project • Provides specification, protocols, SDK, and integration tools • Unifying all types of telemetry data: traces, metrics, and logs • Vibrant growing community

Different deployment topologies

Is OpenTelemetry stable enough?

• Traces are GA and programming OpenTelemetry Stability languages are mostly up to speed • Metrics are almost GA and programming languages are mostly up to speed • Instrumentation libraries are popping up every single week. Help to accelerate this. • Logs are not ready. But you can use the collector for most things log-related. • TL;DR: yes… start using OpenTelemetry

Time to see some hands-on stuff
