The original title is "Observing AI agents with OpenTelemetry and SigNoz: a practical guide"

Short summary

A practical guide to instrumenting AI agents with OpenTelemetry and visualizing traces in SigNoz, an open-source APM tool. Standard logs fail for non-deterministic agent loops, but distributed tracing lets you see per-span latency, exact prompts, token counts, and tool invocation errors. The tutorial covers installing SigNoz locally via Foundry CLI and writing instrumented Python agent code with nested spans for each agent lifecycle phase.

• •OpenTelemetry spans capture latency, prompts, token counts, and errors for each agent lifecycle phase
• •SigNoz provides a free, local APM dashboard as an alternative to expensive SaaS observability platforms
• •Tutorial includes CLI setup commands and Python instrumentation code with span attributes for model and cost metadata
