Collecting this telemetry data is one of the most important things when it comes to Observability. In this episode of talkin’ Observability, we will be talking with Pavol Loffay who is one of creators of Hypertrace Java Agent and worked significantly on projects like OpenTelemetry, Jaeger and, Hypertrace, about telemetry data collection, OpenTelemetry project and hear his advice for people who are getting started with Observability.
