Monitoring Disk Usage
Use tools like `df`, `du`, and `iostat` to monitor disk space, inode usage, and I/O performance of your server storage.
Why Monitor Disk Usage?
Keeping an eye on your server's disk usage is crucial. Imagine a website suddenly going down because its logs filled up the entire disk! Or a database slowing to a crawl due to heavy disk activity.
Monitoring helps you:
- Prevent outages: Catch full disks before they cause problems.
- Optimize performance: Identify disks with high I/O that might be bottlenecks.
- Plan capacity: Understand growth trends to add storage proactively.
Meet `df`: Disk Free
The df command stands for 'disk free'. It's your go-to tool for checking the overall disk space usage of mounted file systems on your server.
It provides a summary of total space, used space, available space, and percentage used for each mounted partition.
