1. **Resource group sample output** — Command used `westeurope` but the sample JSON had `"location": "eastus"`. That contradicts Azure behavior and was updated to **`westeurope`**.
2. **Activity log section (material error)** — The text said the rule fires when a **VM is deleted**, but **`category=ServiceHealth`** is for **Service Health** activity log events (platform incidents/health), not VM deletion. Administrative/delete scenarios use other fields (e.g. `category` / `operationName` for administrative operations). The **heading, explanation, and links** were updated so they match the command, the alert name `service-health-alert`, and the sample JSON. **`azlocal`** was not touched.
3. **Delete section** — Wording now explicitly refers to **metric** alerts and **metric** list output, since other resources (action group, activity log alert) are not removed in that step; `[]` is only accurate for **`metrics alert list`**, not “everything in the RG.”
This pull request adds an article on Azure Monitor Metric Alert to the Azure emulator documentation.
