Agent Factory: Top 5 Agent Observability Best Practices for Reliable AI

Author: Yina Arenas

Ensuring that AI agents are reliable, safe, and high-performing is vital as agentic AI integrates into enterprise workflows. In this post, we explore agent observability best practices, design patterns, and the tools available—centered on Azure AI Foundry Observability—for building and maintaining robust agentic AI systems.

Why Agent Observability Matters

Observability in AI agents supports:

Early detection and resolution of issues
Validation of quality, safety, and compliance
Optimization for performance and user experience
Maintaining trust and accountability

With increasingly complex multi-agent and multi-modal solutions, visibility into how agents think, behave, and make decisions is essential for scaling AI responsibly.

What Is Agent Observability?

Agent observability means gaining actionable visibility into how agents operate from development, through testing, to live production. This includes:

Continuous monitoring: Real-time tracking of agent actions, tool calls, and decisions
Tracing: Step-by-step recording of agent reasoning, tool selection, workflow, and collaboration
Logging: Capturing internal state changes for debugging and audits
Evaluation: Systematic validation of agent actions, outputs, quality, safety, and compliance using both automated and human-driven methods
Governance: Enforcing operational, regulatory, and ethical guidelines

How Agent Observability Differs from Traditional Observability

Whereas traditional observability focuses on system health and performance (metrics, logs, traces), agent observability adds evaluations (of task performance, safety, etc.) and governance for compliance and responsible AI. This deeper approach captures not only what an agent does but why and how, offering confidence and trust in real-world deployments.

Azure AI Foundry Observability Overview

Azure AI Foundry Observability is an end-to-end platform for evaluating, monitoring, tracing, and governing your AI agent lifecycle on Azure. Key capabilities include:

Model leaderboards to compare foundation models on quality, safety, performance, and cost
Continuous evaluations via agent evaluators (intent resolution, tool selection, task adherence, response completeness)
CI/CD integration using GitHub Actions and Azure DevOps extensions for automated quality and safety checks
AI Red Teaming Agent for adversarial testing to surface vulnerabilities
Real-time monitoring and alerting via Azure Monitor & Workbooks
Integrated governance (Microsoft Purview, Credo AI, Saidot) supporting regulatory frameworks like the EU AI Act

Five Best Practices for Agent Observability

1. Use Model Leaderboards for Selection

Compare foundation models in Azure AI Foundry using benchmark leaderboards. Evaluate models on data-driven criteria to balance quality, safety, and cost.

2. Evaluate Continuously in Development and Production

Apply automated evaluations in development and ongoing operations. Assess agents for task performance, intent resolution, tool call accuracy, risk, and safety.

3. Integrate Evaluations with CI/CD Pipelines

Automate agent evaluations for every code change. CI/CD integration ensures regressions are caught promptly and production standards are maintained.

4. Scan for Vulnerabilities using AI Red Teaming

Before going live, simulate adversarial attacks on agents. The AI Red Teaming Agent exposes vulnerabilities and helps validate end-to-end workflows for safety and robustness.

5. Monitor Agents Continuously with Tracing and Alerts

Deploy real-time dashboards and alerts to track ongoing agent performance, resource usage, and security posture. Azure Monitor and Application Insights enable deep operational visibility.

Summary

Agent observability is key to deploying and scaling AI agents responsibly in the enterprise. Azure AI Foundry Observability unifies monitoring, tracing, evaluation, and governance throughout the AI lifecycle, allowing organizations to confidently build and operate trustworthy AI systems.
