UModel Query — read entities, relationships, the model, and telemetry

UModel is an object-graph semantic layer: enterprise objects (services, Pods, deployments, config changes, promotions, …), their typed relationships (calls, depends_on, affects, …), and the datasets (metrics, logs) hanging off them — all read through one SPL surface via the umctl CLI (MCP alternative at the bottom).

This file is the overview + setup. Each query surface has a focused guide under references/ — read the one your task needs (don't load them all).

Setup (CLI-first)

1. Ensure umctl is on PATH — UModel's read CLI:

command -v umctl || go install github.com/alibaba/UnifiedModel/cmd/umctl@latest   # needs Go 1.22+
