# Usage, cost, and quality

> Measure adoption, latency, spend, and reliability across your agent fleet.

Use the Monitoring views to understand how agents are used and how they perform over time.

Track:

* Message and run volume by agent, user, model, and time period.
* Model and provider usage, token consumption, and cost.
* Latency, tool activity, and failure rates.
* Eval outcomes, judge signals, and user feedback.

Start with aggregate trends to identify a change in adoption, spend, or reliability. Then drill into the relevant run traces to find the concrete source of the change. This is the operational feedback loop for self-improvement: observe a pattern, diagnose the cause, make a governed change, and verify it with evals.
