CPU Panel

The CPU panel shows processor and load information for the Unix system:

Processors

Processors	The number of CPUs in the machine you are diagnosing.
CPU Spinner	The CPU load across all CPUs on the machine as a percentage.
User %	The percentage of time the CPU is in the User state, across all CPUs.
System %	The percentage of time the CPU is in the System state, across all CPUs.
Wait %	The percentage of time the CPU is in the Wait state, across all CPUs. Wait is where the machine can only wait for I/O, or something similar, to complete.

Queue Length

The length of the queue in which processes are waiting to be executed. Processes in this queue will be run when the CPU becomes available.

Processes

Total	The total number of processes that are running on the machine you are diagnosing.
Zombies	The number of child processes whose termination has not been acknowledged by their parent process.
Blocked	The number of processes waiting for some event or condition before they can continue execution.

Data flows between the Network panel and CPU panel

Network (Network to CPU)	Rate of incoming network data The incoming rate of data to the server. Note: Spotlight contributes to the data traffic as part of its diagnostic activities.
Network (CPU to Network)	Rate of outgoing network data The outgoing rate of data from the server. Note: Spotlight contributes to the data traffic as part of its diagnostic activities.
Network Errors (Network to CPU)	Rate of incoming network errors The rate at which errors are received from the network.
Network Errors (CPU to Network)	Rate of outgoing network errors The rate at which errors are sent from the machine to the network.

Data flows between the CPU panel and the Memory panel

The rate data is written to / from memory. The unit of measure is dependent on the Operating System.

Operating System	Unit of Measure
Sun Solaris	Kilobytes per second
HP-UX	Pages per second
IBM AIX	Pages per second
Linux	Kilobytes per second. Old versions of the kernel may measure in blocks per second. Refer to your Linux documentation.

Memory Panel

The Memory panel displays detailed information about the physical and virtual memory on the Unix system. It shows statistics such as:

Physical RAM

Total RAM	The total amount of memory in RAM chips.
Free	The amount of physical memory that is free.

Virtual Memory

Max Size	The total amount of virtual memory for the system.
Free	The amount of virtual memory that is free or unused.
Used %	The amount of virtual memory consumed, expressed as a percentage of the Max Size.

Processes Swapped

Where applicable, this is the number of processes whose pages have all been moved into swap space.

Data flows between the Memory panel and the CPU panel

The rate data is written to / from memory. The unit of measure is dependent on the Operating System.

Operating System	Unit of Measure
Sun Solaris	Kilobytes per second
HP-UX	Pages per second
IBM AIX	Pages per second
Linux	Kilobytes per second. Old versions of the kernel may measure in blocks per second. Refer to your Linux documentation.

Data flows between the Memory panel and the Swap Space panel

Swapping (Memory to Swap Space)	The rate at which processes are being swapped out to disk.
Swapping (Swap Space to Memory)	The rate at which processes are being swapped in from disk.

Data flows between the Memory panel and the Disk Activity panel

Disk I/O (Memory to Disk Activity)	The number of writes that the system makes to disk per second.
Disk I/O (Disk Activity to Memory)	The number of reads that the system makes from disk per second.

Swap Space Panel

The Swap Space panel shows the configured swap space on the Unix system:

The total amount of configured swap space on the system.
The amount of swap space currently in use.

Data flows between the Memory panel and the Swap Space Panel

Swapping (Memory to Swap Space)	The rate at which processes are being swapped out to disk.
Swapping (Swap Space to Memory)	The rate at which processes are being swapped in from disk.
