Observability

Observability examples enact what you’d add to a production deployment. Sources under examples/observability/.

Name	Scenario	Source
`obs_event_system`	Add lightweight LLM-call timing logs without changing the chain code — attach a `TimedLogger` Observer.	src
`obs_evaluation`	Regression eval — given 5 known (question, expected_answer) pairs, score the agent. Run in CI.	src
`obs_health_monitoring`	Pre-flight provider check — verify the LLM is reachable at startup; fail fast with a clear error.	src

How to run

COGNIS_PROVIDER=ollama COGNIS_OLLAMA_MODEL=llama3.1 \
  cargo run -p cognis-examples --example obs_evaluation
