Monitoring production agent lifecycle with AWS DevOps Agent and AgentCore Evaluations | Amazon Web Services
Multi-agent systems in production experience issues in ways that traditional monitoring misses. For example, the agent can’t invoke its foundation model (FM) and returns an empty response. This could be because of a missing AWS Identity and Access Management (IAM) permission on an agent’s execution role that doesn’t throw a 500 error. A supervisor agent with a poorly scoped prompt doesn’t increase error rates but instead starts routing 20 percent of requests to the unintended specialist while the infrastructure metrics stay green.
