Why multi-agent tracing is harder than single-call tracing
Multi-agent tracing challenges exceed single-call observability: async spans, non-deterministic routing, and cost attribution need different tooling.
Visualizing multi-agent execution graphs for debugging
A practical guide to visualizing multi-agent execution graphs for debugging: capture spans, model nodes and edges, render with Mermaid, and attribute costs.
Tracing tool calls across a LangGraph multi-agent system
A hands-on tutorial for tracing tool calls LangGraph multi-agent systems: instrument agents, propagate context, and inspect execution flows with code.
Tracing CrewAI agent workflows end to end
Learn how to implement end-to-end tracing for CrewAI multi-agent workflows with step callbacks and OpenTelemetry, plus resilient LLM routing.
Tracing agent-to-agent handoffs in multi-agent systems
A practical guide to tracing agent-to-agent handoffs in multi-agent systems: instrument spans, propagate context, and verify flows.
Monitoring token cost across multi-agent orchestration
A practical guide to tracking token cost multi-agent orchestration: instrument agents, attribute usage, set guardrails, and avoid billing surprises.
Logging agent state transitions for postmortem debugging
Learn how to implement logging agent state transitions with structured events and trace IDs for effective postmortem debugging of multi-agent systems.
Detecting agent hallucination cascades before they compound
Practical steps to detect agent hallucination cascades in multi-agent systems before they compound, using tracing, assertions, and structured eval.
Debugging why one agent's output silently breaks another
Step-by-step guide to debugging agent output failures in multi-agent pipelines: capture raw handoffs, validate contracts, and reproduce breaks in isolation.
Debugging multi-agent deadlocks with distributed tracing
Step-by-step guide to debugging multi-agent deadlocks with distributed tracing: instrument LLM agents, correlate spans, and resolve cyclic dependencies.
Debugging infinite loops in multi-agent LLM workflows
Practical steps to diagnose and fix runaway agent cycles in workflows: tracing messages, bounding retries, and verifying termination in multi-agent systems.
Correlating traces across supervisor and worker agents
A practical guide to correlating traces supervisor worker agents in multi-agent systems: propagation, instrumentation, and pitfalls for engineers.
Building a trace timeline for parallel agent execution
Step-by-step guide to building a trace timeline for parallel agent execution in multi-agent systems using OpenTelemetry and Python with runnable code.
