Logs Are All You Need: Rethinking Observability with AI Agents
Sherwood Callaway introduces Sazabi, an AI-native observability platform designed to disrupt traditional tools like Datadog by focusing on logs as the primary source of truth. The core philosophy is that in the age of coding agents, engineers should interact with production data via natural language chat rather than complex dashboards. Key technical innovations include using Git for persistent agent memory across multiple threads and implementing a read-only sandbox environment to safely execute investigative tasks.
Key takeaways
-
Logs are Sufficient: Rethinking Observability
22:20
The traditional 'three pillars' (metrics, logs, traces) are considered overkill for modern agentic workflows. By focusing solely on logs, instrumentation becomes significantly simpler, requiring only basic logging statements, as the platform can reconstruct metrics and traces from log data.

AI Agents Generate Alerts, They Don't Evaluate Them
28:00
Instead of using AI to triage noisy alerts (alert fatigue), Sazabi autonomously generates actionable alerts directly from logs and codebase analysis. The agent determines what is meaningful to the user at runtime.
-
Agent Memory via Git for Shared State
34:05
Sazabi maintains persistent, shared memory across multiple parallel sub-agents and threads by committing findings (e.g., issue lists, facts) to a dedicated Git branch within the sandbox environment. This allows agents to benefit from collective findings.
-
Sandbox Isolation and Read-Only Access
30:30
The platform operates in a read-only system with no public internet access, ensuring security. All actions are routed through an isolated sandbox environment (e.g., using `bash` tools) to prevent data exfiltration or unauthorized changes.
