The "Logic Span": Using OpenTelemetry to Trace Hallucinations

📰 Dev.to AI

Learn to use OpenTelemetry to trace and debug hallucinations in LLMs, improving the reasoning and decision-making of AI agents

advanced Published 6 May 2026
Action Steps
  1. Install OpenTelemetry in your project to collect tracing data
  2. Configure OTel to track LLM requests and responses
  3. Use OTel to identify hallucinations and errors in the agent's decision-making process
  4. Analyze the tracing data to understand the reasoning behind the agent's actions
  5. Apply fixes and updates to the LLM or agent to improve its reasoning and decision-making

The Signal: The 500 Error of the Mind You’re staring at a "Task Failed" status in your dashboard. You check your logs and see a clean 200 OK from the LLM provider. The network was fast, the JSON parsed correctly, but the agent still decided that the best way to "Summarize an Invoice" was to delete the database entry for it. Most developers use OpenTelemetry (OTel) to find slow database queries or network bottlenecks. But in 2026, the bottleneck isn't the network—it's the Reasoning.
