What is a primary goal of instrumenting tool calls?

• A. To obfuscate internal metrics
• B. For observability—to monitor usage, latency, success rates, and errors
• C. To slow down the system
• D. To disable error reporting

Answer: (B)

Observability through instrumenting tool calls is about gaining visibility into how the system behaves. By adding instrumentation, you collect data on usage patterns, latency, success rates, and errors, which lets you monitor performance, diagnose issues, and understand where to improve. This information forms the basis for dashboards, alerts, and informed decisions about capacity and resilience.

Obfuscating internal metrics would hide the very signals you need to understand behavior, so it defeats the purpose. Slowing down the system contradicts the goal of reliable performance. Disabling error reporting removes crucial visibility into failures, making it harder to detect and fix problems.
