Instrumentation is that black magic that makes our application emit traces, logs, metrics or other telemetry. How does it work? What options are available in different programming languages, such as Java, Python and Go? What does OpenTelemetry offer in this domain?   On this episode of OpenObservability Talks I hosted Eden Federman, Co-Founder & CTO at keyval, a company focused on making observability simpler. Eden is the creator of two open source projects: Odigos and Go automatic instrumentation (now part of OpenTelemetry). Eden is passionate about everything related to observability and performance monitoring. He also created kubectl-flame, a profiler for Kubernetes.
