Although native metrics export is not yet available, you can still approximate critical key performance indicators (KPIs) by analyzing server logs. These manual methods provide insight into tool usage, error trends, and performance characteristics until built-in observability features are introduced. Some of the manual methods include:

  • Tool invocation rate—Count log lines containing the Invoking tool pattern.

  • Error ratio—Compare the number of 4xx and 5xx status lines against total tool invocations.

  • Latency—If timing middleware is enabled, parse timing records from logs to estimate response times.
