Monitoring the Swarm
When an agent is live, you need specialized observability tools like LangSmith, Langfuse, or Arize.
Key metrics to track:
- Time-to-Task-Completion: How long does the full agent loop take?
- Tool Error Rate: How often do tools fail, and does the agent successfully recover?
- Token Burn Rate: Which specific agents or tasks are consuming the most tokens?
- Escalation Rate: How often does the agent give up and ask the human for help?
🎯 Final Mastery Tip: The best agent engineers spend 20% of their time writing prompts and 80% of their time building robust tools, state management, and evals.
