Zipkin for LLM agents: Zipkin is the “get tracing working today” option. It’s lightweight, approachable, and perfect when you want quick visibility into service latency and failures without adopting a full observability suite.

For LLM agents, Zipkin can be a great starting point: it helps you visualize the sequence of tool calls, measure step-by-step latency, and detect broken context propagation. This guide covers how to use Zipkin effectively for agent workflows, and when you should graduate to Jaeger or Tempo.

TL;DR

• Zipkin is a lightweight tracing backend for visualizing end-to-end latency.
• Model 1 agent request as 1 trace; model tool calls as spans.
• Add run_id + tool.name attributes so traces are searchable.
• Start with Zipkin for small systems; move to Tempo/Jaeger when volume/features demand it.

What Zipkin is good for

• Small to medium systems where you want quick trace visibility.
• Understanding latency distribution across steps (model call vs tool call).
• Detecting broken trace propagation across services.

How to model agent workflows in traces

Keep it simple and consistent:

• Trace = one agent run (one user request)
• Spans = planner, tool calls, retrieval, final compose
• Attributes = run_id, tool.name, http.status_code, retry.count, llm.model, prompt.version

Setup overview: OTel → Collector → Zipkin

A clean approach is to use OpenTelemetry everywhere and export to Zipkin via the Collector:

receivers:
  otlp:
    protocols:
      grpc:
      http:

processors:
  batch:

exporters:
  zipkin:
    endpoint: http://zipkin:9411/api/v2/spans

service:
  pipelines:
    traces:
      receivers: [otlp]
      processors: [batch]
      exporters: [zipkin]

Debugging tool calls and retries

• Slow agent? Find the longest span. If it’s a tool call, inspect status/timeout/retries.
• Incorrect output? Trace helps you confirm which tools were called and in what order.
• Fragmented traces? That’s usually missing context propagation across tools.

When to move to Jaeger or Tempo

• Move to Jaeger when you want a more full-featured tracing experience and broader ecosystem usage.
• Move to Tempo when trace volume becomes high and you want object-storage economics.

Privacy + safe logging

• Don’t store raw prompts and tool arguments by default.
• Redact PII and secrets at the Collector layer.
• Use short retention for raw traces; longer retention for derived metrics.

Tools & platforms (official + GitHub links)

• Zipkin: zipkin.io | GitHub
• OpenTelemetry: opentelemetry.io
• OpenTelemetry Collector: GitHub

Production checklist

• Add run_id to traces and your app logs.
• Instrument planner + each tool call as spans.
• Validate context propagation so traces don’t fragment.
• Use the Collector for batching and redaction.
• Revisit backend choice when volume grows (Jaeger/Tempo).
