OpenTelemetry·52wOpenTelemetry Logging and You
OpenTelemetry provides a comprehensive logging framework that includes logs, events, and spans. Logs are any telemetry data emitted through a log pipeline via the Logs API, while events are a specific type of log with a defined schema. Spans differ from events by having durations and hierarchical relationships. The design emphasizes correlating all telemetry signals through context for a cohesive observability solution.
Hacker News·51wObservability 2.0 and the Database for It
Observability 2.0 moves beyond the traditional three pillars of metrics, logs, and traces to adopt wide events, which serve as high-cardinality, context-rich data sources for comprehensive system insights. GreptimeDB, an open-source database, is designed to support this new paradigm by efficiently storing and processing wide events. It offers features like high-throughput real-time data ingestion, query APIs, and integration with existing tools like OpenTelemetry. The shift aims to eliminate data silos, reduce redundant data, and enable flexible, scalable observability solutions.
Lobsters·1yBPF From Scratch In Rust
Learn how to write a BPF program in Rust from scratch without using macros, frameworks, or hidden helpers. The post explains how to set up the Rust build toolchain, write a minimal BPF program that hooks into a tracepoint, and use the 'yeet' CLI and its daemon 'yeetd' to load and manage the BPF program. A step-by-step guide is provided to create, build, and run the BPF program, ensuring it integrates seamlessly with the Linux kernel and prints live output to the trace pipe.
