> Add System Disk Information Endpoint to Cassandra Sidecar
> ---------------------------------------------------------
>
> Key: CASSSIDECAR-366
> URL: https://issues.apache.org/jira/browse/CASSSIDECAR-366
> Project: Sidecar for Apache Cassandra
> Issue Type: New Feature
> Components: Rest API

> Want to introduce a new REST API endpoint to retrieve system disk
> information, providing storage capacity and usage metrics for all mounted
> file systems on the host.
>
> Use Cases
>
> - Monitor disk space across Cassandra nodes
> - Can be used to alert on low disk space conditions
> - Helps for capacity planning and operational troubleshooting
>
> New REST Endpoint:
>
> - Path: /api/v1/system/disk-info
> - Method: GET
> - Authorization: Requires SYSTEM permission (a new permission that will be
> added)
> - Response: JSON array of disk information objects
>
> Sample Response:
> {noformat}
> [
> {
> "totalSpace": 1000000000000,
> "freeSpace": 500000000000,
> "usableSpace": 450000000000,
> "name": "data1",
> "mount": "/dev/sda1",
> "type": "ext4"
> }
> ]
> {noformat}
> Proposing to add OSHI library as a dependency to fetch the disk information.
> OSHI is a free JNA-based (native) Operating System and Hardware Information
> library for Java. It provides a cross-platform implementation to retrieve
> system information such as OS version, processes, memory and CPU usage, disks
> and partitions, devices, and sensors without requiring additional native
> libraries. This library uses the MIT License.
