4.11.1.3 User Action

A high percentage of I/O wait can indicate a hardware problem, a slow NFS server, or poor load-balancing among local file systems and disks. Check the system messages log for any hardware errors. Use the iostat -xn command or the nfsstat -c (NFS client-side statistics) command or both to determine which disks or file systems are slow to respond. Check to see if the problem is with one or more swap partitions, as lack of swap or poor disk load balancing can cause these to become overloaded. Depending on the specific problem, fixes may include: NFS client or server tuning, hardware replacement, moving applications to other file systems, adding swap space, or restructuring a file system for better performance.

4.11.4 CPU Interrupt Time (%)

Represents the percentage of time the processor spends receiving and servicing hardware interrupts during sample intervals. This value is an indirect indicator of the activity of devices that generate interrupts, such as the system clock, the mouse, disk drivers, data communication lines, network interface cards, and other peripheral devices. These devices normally interrupt the processor when they have completed a task or require attention. Normal thread execution is suspended during interrupts. Most system clocks interrupt the processor every 10 milliseconds, creating a background of interrupt activity. Suspends normal thread execution during interrupts.

This metric is available only on Windows.

4.11.15.3 User Action

For UNIX-based platforms, check the swap usage using the UNIX top command or the Solaris swap -l command. Additional swap can be added to an existing file system by creating a swap file and then adding the file to the system swap pool. (See documentation for your UNIX OS). If swap is mounted on /tmp, space can be freed by removing any junk files in /tmp. If it is not possible to add file system swap or free up enough space, additional swap will have to be added by adding a raw disk partition to the swap pool. See UNIX documentation for procedures.

For Windows, check the page file usage and add an additional page file if current limits are insufficient.

4.14.2 Cache Faults (per second)

Cache Faults/sec is the rate at which faults occur when a page sought in the file system cache is not found and must be retrieved from elsewhere in memory (a soft fault) or from disk (a hard fault). The file system cache is an area of physical memory that stores recently used pages of data for applications. Cache activity is a reliable indicator of most application I/O operations. This metric shows the number of faults, without regard for the number of pages faulted in each operation.

This metric shows the number of copies, without regard for the number of pages copied in each operation.

Demand Zero Faults/sec is the rate at which a zeroed page is required to satisfy the fault.

Windows maintains a list of zeroed pages to accelerate this process. This metric shows the number of faults, without regard to the number of pages retrieved to satisfy the fault.

4.14.6 Page Faults (per second)

Page Faults/sec is the average number of pages faulted per second. It is measured in number of pages faulted per second because only one page is faulted in each fault operation, hence this is also equal to the number of page fault operations. This metric includes both hard faults (those that require disk access) and soft faults (where the faulted page is found elsewhere in physical memory.) Most processors can handle large numbers of soft faults without significant consequence. However, hard faults, which require disk access, can cause significant delays.

This metric is available only on Windows.

4.14.8 Page-in Requests (per second)

For UNIX-based systems, represents the number of page read ins per second (read from disk to resolve fault memory references) by the virtual memory manager. Along with Page Outs, this statistic represents the amount of real I/O initiated by the virtual memory manager. This metric checks the number of page read ins for the CPU(s) specified by the Host CPU(s) parameter, such as cpu_stat0 or * (for all CPUs on the system).

For Windows, this metric is the rate at which the disk was read to resolve hard page faults. It shows the number of reads operations, without regard to the number of pages retrieved in each operation. Hard page faults occur when a process references a page in virtual memory that is not in working set or elsewhere in physical memory, and must be retrieved from disk. This metric is a primary indicator of the kinds of faults that cause systemwide delays. It includes read operations to satisfy faults in the file system cache (usually requested by applications) and in non-cached mapped memory files.

4.14.9 Page-out Requests (per second)

For UNIX-based systems, represents the number of page write outs to disk per second. This metric checks the number of page write outs for the CPU(s) specified by the Host CPU(s) parameter, such as cpu_stat0 or * (for all CPUs on the system).

For Windows, this metric is the rate at which pages are written to disk to free up space in physical memory. Pages are written to disk only if they are changed while in physical memory, so they are likely to hold data, not code. This metric shows write operations, without regard to the number of pages written in each operation.

4.14.10 Pages Paged-in (per second)

For UNIX-based systems, represents the number of pages paged in (read from disk to resolve fault memory references) per second. This metric checks the number of pages paged in for the CPU(s) specified by the Host CPU(s) parameter, such as cpu_stat0 or * (for all CPUs on the system).

For Windows, this metric is the rate at which pages are read from disk to resolve hard page faults. Hard page faults occur when a process refers to a page in virtual memory that is not in its working set or elsewhere in physical memory, and must be retrieved from disk. When a page is faulted, the system tries to read multiple contiguous pages into memory to maximize the benefit of the read operation.

4.14.11 Pages Paged-out (per second)

For UNIX-based systems, represents the number of pages written out (per second) by the virtual memory manager.

This metric checks the number of pages paged out for the CPU(s) specified by the Host CPU(s) parameter, such as cpu_stat0 or * (for all CPUs on the system).

For Windows, this metric is the rate at which pages are written to disk to free up space in physical memory. Pages are written back to disk only if they are changed in physical memory, so they are likely to hold data, not code. A high rate of pages output might indicate a memory shortage. Windows writes more pages back to disk to free up space when physical memory is in short supply.

If this number is zero or closer to zero, then you can be sure the system has sufficient memory. If the number is always high, then adding memory will definitely help.

4.14.14 Transition Faults (per second)

Transition Faults/sec is the rate at which page faults are resolved by recovering pages that were being used by another process sharing the page, or were on the modified page list or the standby list, or were being written to disk at the time of the page fault. The pages were recovered without additional disk activity. Transition faults are counted in numbers of faults; because only one page is faulted in each operation, it is also equal to the number of pages faulted.

This metric is available only on Windows.

Check the swap usage using the UNIX top command or the Solaris swap -l command. Additional swap can be added to an existing file system by creating a swap file and then adding the file to the system swap pool. (See documentation for your UNIX OS). If swap is mounted on /tmp, space can be freed by removing any junk files in /tmp. If it is not possible to add file system swap or free up enough space, additional swap will have to be added by adding a raw disk partition to the swap pool. See UNIX documentation for procedures.
