is already in main memory or if it is in use by another process with which the page is shared.

There are two types of page faults:

◦ Hard Page Fault—The most expensive in terms of system resource usage, occurring when

a missing page must be retrieved from the disk.

◦ Soft Page Fault—Generally not considered a source of memory bottlenecks, occurring

when the missing page is not in the current working set but is located elsewhere in memory

and easily brought into the working set.

• Hard Page Faults %—Ratio of page faults per second to pages input per second. This value

is a primary indication of memory bottlenecks.

Memory performance is determined primarily by the rate at which memory is swapped out to disk.

Page Reads/Sec is the primary factor in determining memory performance issues, but the Hard

Page Faults % and Available MBytes are also considered.

Memory Inventory

• System Memory

Physical memory installed in the server◦

◦ Amount of memory that can be addressed by the operating system

◦ Any server-specific memory technology or configurations

• Memory Board—Configuration of the memory boards and lists the number of DIMMs configured

in each particular DIMM socket and any empty sockets

• Memory Configuration recommendations—Server specific memory recommendations (for G7

servers and above), if any

Network connections

The following information is provided for network connections.

Network Connections Status

• Network MBytes/Sec—Average number of megabytes transferred (transmitted or received)

over the network subsystem each second

• MBits TX/Sec—Average number of megabits transmitted over the network each second

• MBits RX/Sec—Average number of megabits received over the network each second

Network connection performance is determined by the performance of the network adapters.

Network Connection Inventory

• Network Connections Configuration—Number of adapters and ports installed and available

on the server, including any that are disabled

• IP Addresses—All IP addresses assigned to the ports

• Displays the NIC teaming information and the NIC adapters involved in teaming of a monitored

server

Network adapter

The following information is provided for a network adapter.
