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.
