Observability Model

Responsibility View

This document defines how the platform monitors its health and alerts on failures. It answers the question: How do we know if something is wrong?

Signal Flow

The platform collects signals from all layers and aggregates them into actionable dashboards and alerts.

Core Signals

Metrics (Availability & Performance)

Numerical data points (CPU, Memory, Latency, Error Rate) used to determine the real-time health of a component.

Logs (Context & Security)

Textual records of events. Used for post-mortem analysis, security auditing, and troubleshooting complex failures.

Health Checks (Integrity)

Active probing of service endpoints (e.g., /healthz). This determines if a workload is ready to receive traffic or needs to be restarted.
