Collecting every trace in a high-volume system is wasteful and expensive. Learn why sampling is statistically sound, how head and tail sampling differ, and how the OpenTelemetry Collector gives you the control to do it right.
Traces, Metrics, Logs, Baggage, and Profiles: the definitive guide to understanding OpenTelemetry's five signal types and how they fit into a real observability strategy.
Running LLMs in production is not like running a REST API. Here's how to instrument, trace, and monitor large language models, AI agents, and retrieval-augmented generation pipelines so you can actually debug them when they fail.
Unstructured logs are a liability in distributed systems. Here's how to design structured, JSON-based logging that correlates with traces, survives high cardinality, and actually helps you debug at 3am.
The circuit breaker prevents cascading failures, but without proper instrumentation you're blind to why it trips. Here's how to make it observable end-to-end.
Trace propagation through message queues and async workers looks straightforward until it isn't. Here's what actually breaks and how to fix it.
