Automatic MinIO Storage Capacity Alerts
Every hour, WebRun opens the MinIO console, reads storage usage for every bucket against its available capacity, drafts a Gmail alert the moment one crosses 80 percent, and logs the reading to Airtable so usage trends are visible over time.
How do I get warned before a MinIO bucket runs out of storage?
WebRun checks every MinIO bucket's storage usage every hour against its available capacity. It drafts a Gmail alert the moment a bucket crosses 80 percent, naming the bucket and its current usage, and logs the reading to Airtable so the team can see the trend. It never expands storage or deletes objects on its own, that stays a human decision.
- Bucket capacity gets an early alert instead of a failed write
- Every hourly reading is logged for trend analysis
- Storage changes stay a manual, reviewed decision
Built for DevOps teams · backend engineers · data platform teams · companies self hosting object storage

Questions, answered
Does it expand storage or delete old objects to free space?
No. WebRun only reads usage figures and drafts an alert. Expanding storage, archiving, or deleting objects stays a manual step your team takes.
Why draft the alert instead of sending it straight away?
Capacity decisions often mean a real infrastructure change, so WebRun leaves the email as a draft for a human to review and send.
Can we see how usage has trended over time?
Yes. Every hourly reading is logged to Airtable, so you can see whether a bucket is filling gradually or spiking suddenly.
