Fields

Field name

Explanation

1-Minute Run Queue Avg

The average number of threads over the last one minute, other than threads waiting in the execution queue for the kernel.

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.

15-Minute Run Queue Avg

The average number of threads over the last 15 minutes, other than threads waiting in the execution queue for the kernel.

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.

5-Minute Run Queue Avg

The average number of threads over the last 5 minutes, other than threads waiting in the execution queue for the kernel.

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, it includes processors after logical partitioning by the Micro-Partitioning function).

Context Switches

Number of times the context switch is executed.

Idle %

Percentage of time in idle status (%).

This is also the average value of the percentage for each processor (for AIX, it includes processors after logical partitioning by the Micro-Partitioning function).

Kernel CPU %

Percentage of operation time in kernel mode (%).

This is also the average value of the percentage for each processor (for AIX, it includes processors after logical partitioning by the Micro-Partitioning function).

Record Time

Time when the record was created (Greenwich Mean Time).

System Calls

Number of times a system call was issued.

User CPU %

Percentage of operation time in user mode (%).

This is also the average value of the percentage for each processor (for AIX, it includes processors after logical partitioning by the Micro-Partitioning function).

Wait %

Percentage of time in I/O waiting status (%).

This is also the average value of the percentage for each processor (for AIX, it includes processors after logical partitioning by the Micro-Partitioning function).
