# 07.07.2025: Database disk usage monitor

> Available in Phoenix 11.5+

<Update label="07.07.2025" description="">
  ## Database Disk Usage Monitor

  **New Features:**

  * Added a **disk usage monitor daemon** that periodically checks storage consumption.

  * Sends **warning emails** to administrators when usage crosses a configured threshold.

  * **Blocks insert/update operations** when usage exceeds a higher critical threshold.

  * Introduced **configurable environment variables** for warning and blocking thresholds with validation.

  * Integrated disk usage checks into both the **FastAPI app** and **gRPC serve** to enforce write blocked.

  **Enhancements:**

  * Extended the email sender with a method and HTML template specifically for **disk usage alert notifications**.
