Philly ETE 2023 — Your Distributed System is Talking to You: OpenTelemetry — Jessica Kerr



Jessica will describe what distinguishes modern event-based observability from earlier standards of logging and monitoring; how it is implemented using OpenTelemetry; and what miracles we can perform when we have it.

For monitoring, debugging, and performance-tuning software systems, the modern standard is event-based observability with distributed tracing. This is now an industry standard: OpenTelemetry is the 2nd biggest project in the Cloud Native Compute Foundation (after Kubernetes).

Great observability lets you employ complexity to deliver value, while still understanding what’s happening in the system, at need.
