How to Track Disk Space Usage Over Time on a Linux Server
Disk space rarely disappears all at once. On most servers, it fills gradually — a growing log directory here, an expanding database there — until one day the disk is full and something breaks. Tracking disk space usage over time on your Linux server gives you the context to understand how fast your storage is actually growing. With that visibility, you can act weeks ahead of a problem instead of scrambling when a service goes down.
