The next two lines are dedicated to memory information, and aren’t relevant for monitoring CPU usage. Example: the CPU needed to “steal” resources from a virtual machine in order to process the physical machine’s workload.

st: Percentage of CPU time that was stolen from a virtual machine.

Example: a high priority service interrupting the CPU.

si: Percentage of CPU time spent processing software interrupts.

Example: the network card (or any piece of hardware) interrupting the CPU to notify it that new data has arrived.

hi: Percentage of CPU time spent processing hardware interrupts.

Example: waiting for a hard drive to finish reading data.

wa: Percentage of CPU time spent on waiting on I/O from hardware.

ni: Percentage of CPU time spent on running processes with a user-defined priority (a specified nice value).sy: Percentage of CPU time spent in kernel space (running system processes).us: Percentage of CPU time spent in user space (running user-spawned processes).This will open up a display in the terminal that has a live view of services running on the system, the amount of system resources each of those services are using, as well as a summary of the system’s CPU utilization, among other information. A lot of the output from this command is rather complex, but it gives very granular information about how the CPU is being utilized on a system. $ – requires given linux commands to be executed as a regular non-privileged userĪ great way to check the current CPU usage is with the top command. # – requires given linux commands to be executed with root privileges either directly as a root user or by use of sudo command
