A shared inventory
Keep domain, owner, provider, current usage, limit, and last reading date. The information should be reviewable without entering every WordPress site.
Alerts that support action
Use warnings before the critical point. A useful alert identifies the site, resource, percentage used, and recommended action.
Local measurement and central view
Host Gauge measures inside each installation. The Hosting Quota Control connector sends authorized reports to the Hub, where the team manages sites, limits, and licenses.
