A system administrator has been alerted to slow performance on a virtualized Linux server. After checking various system metrics, the administrator finds that a significant amount of processor time is categorized under 'st' when inspecting resource usage with monitoring tools. What does this category represent?
This is the time spent performing calculations for user-initiated processes
Time reserved for low-priority background tasks within the system
The period during which the system is idle and waiting for user interaction
Duration dedicated to running the kernel and its associated processes
Time spent processing input/output operations waiting for external devices
Time allocated by the hypervisor to other virtual processors
