Monitor shared drive quota and send alerts

Track shared drive storage usage via API and notify teams before hitting quota limits to avoid work stoppages.

The problem

Shared drives hitting quota quietly block uploads and break workflows. Manual checks are unreliable and missed warnings result in blocked document creation and file sync errors.

How it works

  1. Enumerate all shared drives via the Drive API.
  2. Query each drive's storage usage and total quota.
  3. Identify drives nearing quota thresholds.
  4. Map drives to notification targets (owners or groups) using metadata or Admin SDK group lookups.
  5. Send alerts by email or chat when thresholds are crossed.

What changes

Admins and teams receive timely warnings before shared drives fill up, reducing user disruption and urgent support tickets.

The trap in this one. Drive API's storage quota fields are only updated after a delay—uploads and deletions can take hours to reflect in the reported usage. An alerting system that triggers on near-quota may repeatedly fire or miss a critical threshold if it assumes real-time accuracy. Always communicate that reported usage is lagging and avoid automated actions (like file deletions) based on stale data.

Questions people ask

Can the API show which files are using the most space?

Yes, but only for files the service account can see. Files added by users with restricted visibility won't appear, so totals may not match reported usage.

How often should quota monitoring run?

Every few hours is typical. Running it more frequently does not improve accuracy, as quota metrics are not real-time.

Want this built?

This is a pattern we run in production. We will set up the delegation and build this on top of it — $500 per hour, most of it working the same day.
