BSides Buffalo 2025 – Modern Application Debugging: An Introduction to OpenTelemetry
June 7 All day

Our colleague Joshua Lee will be speaking at BSides Buffalo 2025 about the Modern Application Debugging: An Introduction to OpenTelemetry.
In this talk, Joshua will share his insights and experiences with OpenTelemetry, an open-source project that offers protocols, APIs, and SDKs for collecting metrics, traces, and logs from applications and services. He will cover the comprehensive toolkit provided by the OpenTelemetry community, including language SDKs, the Collector, and the OTLP formats for metrics, traces, and logs.
He will demonstrate how to instrument and monitor a microservices application running on a Kubernetes cluster, utilizing the full potential of OpenTelemetry. Attendees will learn how to use powerful open-source tools like Jaeger and Prometheus to effectively analyze telemetry signals from their applications.
By the end of this session, attendees will have a solid understanding of how to implement OpenTelemetry in their projects, enhancing their debugging and observability practices. Join us as we delve into the world of OpenTelemetry, unlocking the capabilities of this powerful technology for your development needs.
Benefits to the ecosystem: The talk offers insights into OpenTelemetry’s tools and protocols, helping developers better utilize its capabilities for observability in cloud-native applications. The talk demonstrates how to instrument and observe microservices applications on Kubernetes, which is crucial for optimizing and debugging modern cloud-native systems. By highlighting the integration with tools like Jaeger and Prometheus, it shows how OpenTelemetry can be effectively used within the broader CNCF ecosystem to analyze telemetry signals.
