What operating system tools can be used to collect capacity planning data? (Select TWO correct)

`fuser` identifies processes using specific files or network sockets, which is useful for troubleshooting but not a primary tool for collecting broad, ongoing capacity planning metrics.

`iostat` (input/output statistics) provides metrics on disk I/O activity, CPU utilization, and device loading, which are crucial for assessing the capacity and performance of storage subsystems.

`lsmod` lists currently loaded kernel modules, which is configuration information, not a tool for collecting real-time or historical performance data for capacity planning.

`vmstat` (virtual memory statistics) reports comprehensive system information including memory, CPU, disk I/O, and process activity, offering a broad view of resource usage patterns vital for capacity planning.
