Observability for Copilot: Logs, Metrics, Traces
Observe Copilot in production — what to log, metric design, tracing.
What You Will Learn
- Log Copilot activity.
- Design metrics.
- Implement tracing.
- Build dashboards.
- Alert on anomalies.
Why This Matters
Without observability, you can't diagnose issues or measure impact. This lesson builds the observability stack.
Concept Explained
Observability = logs + metrics + traces. Logs: what happened. Metrics: aggregates (count, latency). Traces: end-to-end request flow.
How It Works
Log every Copilot call (user, surface, prompt, response, latency). Metrics: request count, latency p50/p95/p99, error rate. Traces: end-to-end for debugging.
Step-by-Step Tutorial
1. Log
Every Copilot call: user, surface, prompt (redacted), response (redacted), latency, model.2. Metrics
Request count, latency (p50/p95/p99), error rate, model usage.3. Traces
End-to-end: prompt → Copilot service → model → response.4. Dashboard
Real-time: requests, errors, latency. Daily: top users, top surfaces.5. Alerts
Error rate >5%, p95 latency >5s, model usage anomalies.Real-World Example
A team added observability to their Copilot usage. Found: error rate spiked at 3pm daily (rate limiting). Adjusted usage patterns. p95 latency dropped 30%. Lesson: observability reveals patterns.
Example Prompts / Commands / Code
"""{
"timestamp": "2026-08-30T14:23:45Z",
"user": "alice@corp.com", // or hashed for privacy
"surface": "chat", // inline, chat, cli, agent
"model": "claude",
"prompt_length": 245,
"response_length": 1240,
"latency_ms": 3200,
"credits_used": 15,
"success": true,
"error": null
// Don't log: prompt content, response content (privacy)
}
Stream to: ELK / Datadog / CloudWatch
""""""Real-time:
- Requests per minute (per surface)
- Error rate
- p50/p95/p99 latency
- Active users
Daily:
- Total requests
- Top 10 users
- Top surfaces
- Model usage breakdown
- Credit usage
Weekly:
- Trend charts
- Anomalies
- Capacity planning
"""Common Mistakes
- Logging prompt content — privacy violation.
- No metrics — can't see patterns.
- No traces — can't debug end-to-end issues.
- No alerts — issues detected late.
Best Practices
- Log every Copilot call (redact content).
- Metrics: count, latency, errors, model usage.
- Traces for end-to-end debugging.
- Dashboard: real-time + daily + weekly.
- Alerts: error rate, latency, anomalies.
Troubleshooting
| Problem | How to Fix |
|---|---|
| Logs too verbose | Redact content. Keep metadata only. |
| Dashboard too slow | Pre-aggregate. Use time-series DB. |
Practical Exercise
Your Turn
Design an observability stack for Copilot. Define log schema, metrics, dashboard. Implement logging.
Professional Challenge
Deploy observability: log every Copilot call, build dashboard, set alerts. Run for a month. Document patterns.
Key Takeaways
- Observability = logs + metrics + traces.
- Log every call (redact content).
- Metrics: count, latency, errors, model usage.
- Traces for end-to-end debugging.
- Dashboard + alerts.
