Percent time spent in kernel space.On modern multi-core CPUs, it is often useful to know the CPU usage of individual cores for a particular process. Linux 2.6.11+ Percentage of time a virtual CPU waits for a real CPU while the hypervisor is servicing another virtual processor. Number of software interrupts since boot. Time spent by niced (prioritized) processes executing in user mode this also includes guest_nice time. Time spent for servicing hardware interrupts. This is not accounted in idle time counter. If the CPU has completed all tasks it is idle. Linux 2.6.24+: Time spent running a virtual CPU. A context switch is a procedure that a computer’s CPU (central processing unit) follows to change from one task (or process) to another while ensuring that the tasks do not conflict. Number of context switches (voluntary + involuntary) since boot. OK if user, system, iowait and overall cpu-usage (minus nice) are all below the thresholds within the last -count checks. Top3 processes which consumed the most cpu time: count=5 (the default) while checking every minute means that the check reports a warning if any of user, system, iowait or overall cpu-usage was above a threshold in the last 5 minutes.Ģ.6% - user: 1.6%, system: 0.7%, irq: 0.2%, softirq: 0.1% We check system-wide CPU stats, not per-CPU. Warns only if any of user, system, iowait or overall cpu-usage is above a certain threshold within the last n checks (default: 5). In addition, the top 3 processes which consumed the most CPU time are listed.
Outputs the cpu times having > 0% in the first line, sorted by value. Returns a bunch of numbers representing the current system-wide CPU utilization as a percentage.
