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
The period during which the system is idle and waiting for user interaction
Time spent processing input/output operations waiting for external devices
Duration dedicated to running the kernel and its associated processes
Time reserved for low-priority background tasks within the system
Time allocated by the hypervisor to other virtual processors
