Fields

Field name Explanation

15-Minute Run Queue Avg Average number of threads that were waiting in the run queue in the past 15 minutes.
On HP-UX, Solaris, and AIX, this value does not include the number of threads waiting for I/O. On Linux, this value includes the number of threads waiting for I/O.

CPU % CPU usage (%).
This is also the average value of the percentage for each processor (for AIX 5L V5.3 or later, it includes processors after logical partitioning by the Micro-Partitioning function).

Context Switches Number of times the context switch was executed.

Idle % Percentage of time that the CPU is in idle status (%).
This is also the average value of the percentage for each processor (for AIX 5L V5.3 or later, it includes processors after logical partitioning by the Micro-Partitioning function).

Interrupts Number of times interrupt occurred.

Kernel CPU % Percentage of time that the CPU is operating in kernel mode (%).
This is also the average value of the percentage for each processor (for AIX 5L V5.3 or later, it includes processors after logical partitioning by the Micro-Partitioning function).

Run Queue Number of processes waiting in the queue.

System Calls Number of times a system call was issued.

User CPU % Percentage of time that the CPU is operating in user mode (%).
This is also the average value of the percentage for each processor (for AIX 5L V5.3 or later, it includes processors after logical partitioning by the Micro-Partitioning function).

Wait % Percentage of time that the CPU is in I/O waiting status (%).
This is also the average value of the percentage for each processor (for AIX 5L V5.3 or later, it includes processors after logical partitioning by the Micro-Partitioning function).
