LLM MonitoringAI DashboardToken UsageAI Observability

An LLM API dashboard should answer one question quickly: is our AI system healthy, useful, and affordable?

That requires more than request count.

Core metrics

Track:

  • total requests
  • success rate
  • error rate
  • latency
  • time to first token
  • input tokens
  • output tokens
  • estimated cost
  • model distribution
  • provider distribution

These show operational health.

Cost metrics

Show cost by:

  • model
  • provider
  • feature
  • customer
  • plan
  • environment

This helps teams find expensive workflows.

Reliability metrics

Include:

  • timeout rate
  • retry rate
  • fallback rate
  • rate-limit errors
  • provider health
  • queue delay

Fallback rate is especially important in multi-provider systems.

Quality signals

Add:

  • user feedback
  • regeneration rate
  • validation failures
  • tool call failures
  • escalation rate
  • support complaints

HTTP success does not guarantee answer quality.

Final thoughts

The best LLM API dashboards combine operations, cost, reliability, and quality. They help engineering, product, and finance teams make better model decisions.
