I will talk about the validation and monitoring of AI agents using the example of a mobile application that interacts with a multi-agent system via OpenAPI. I will demonstrate practical approaches to testing agent logic, methods for collecting performance metrics, and setting up an observability system. I will share my experience in tracking agent behavior in real time, detecting anomalies, and ensuring the reliability of a multi-agent architecture in production.

The session covers architectural strategies that keep Elasticsearch stable under heavy load: proper index and shard design, ILM policies, persistent queues in Logstash, metrics downsampling, and self-monitoring of the observability stack. Insights are drawn from operating platforms that handle terabytes of logs and millions of events per day.
