How can you check the current load on the disk in the system?

To check the current disk load on the system, you can use several tools and commands:

• iostat — shows input/output statistics for devices, including disk load and wait times.

  iostat -dx 1 3
  

  Here -d — only disks, -x — extended statistics, 1 3 — update every 1 second, 3 times.

• iotop — an interactive monitor showing processes actively using the disk.

  sudo iotop
  

• vmstat — displays overall system statistics, including input/output blocks.

  vmstat 1 5
  

• dstat — a versatile resource monitoring tool, including disk.

• sar — collects and displays disk statistics over a period.

These tools will help you understand how actively the disk is being used, whether there are delays, and which processes are creating load.
