•
Private Bytes—Current number of bytes this process has allocated that cannot be shared with
other processes.
•
PageFile Bytes—Current number of bytes this process has used in the paging files. Paging
files are used to store pages of memory used by the process that are not contained in other
files. All processes share paging files and a lack of space in paging files can prevent other
processes from allocating memory.
•
Working Set—Current number of bytes in the working set of this process. The working set is
the set of memory pages touched recently by the threads in the process. If free memory in the
computer is above a threshold, pages are left in the working set of a process even if they are
not in use. When free memory falls below the threshold, pages are trimmed from working
sets. If they are needed, they are soft-faulted back into the working set before they leave main
memory.
•
Page Faults/sec—Rate at which the page faults occur in the executing threads within this
process. A page fault occurs when a thread refers to a virtual memory page that is not in its
working set in main memory. This does not cause the page to be fetched from disk if it is on
the standby list and already in main memory, or if it is in use by another process with whom
the page is shared.
•
% CPU Time—Percentage of elapsed time that all the threads of this process used the processor
to execute instructions. An instruction is the basic unit of execution in a computer, a thread is
the object that executes instructions, and a process is the object created when a program is
run. Code executed to handle some hardware interrupts and trap conditions are included in
this count. On multi-processor machines, the maximum value of the counter is 100 % times
the number of processors.
•
% Privileged CPU Time—Percentage of elapsed time that the threads of the process have spent
executing code in privileged mode. When a Windows NT system service is called, the service
often runs in privileged mode to gain access to system-private data. Such data is protected
from access by threads executing in user mode. Calls to the system can be explicit or implicit,
such as page faults or interrupts. Unlike some early operating systems, Windows NT uses
process boundaries for subsystem protection in addition to the traditional protection of user
and privileged modes. These subsystem processes provide additional protection. Therefore,
some work done by Windows NT on behalf of your application might be displayed in other
subsystem processes in addition to the privileged time in your process.
Processor Utilization
This window displays information about the system's processor utilization for different time intervals.
The system processor bar graphs display the percentage of total possible system processor utilization
over the specified period of time. A bar graph is displayed for every processor installed in the
device. Use this graph to determine if the system processor is a performance bottleneck.
System Configuration
Auto Recovery
This section provides Automatic Server Recovery (ASR) configuration information, tells you when
the server was last reset, and allows you to modify pager settings. You can modify the Status, ASR
Reset Boot Option, Pager Status, Pager Dial String, and Pager Message settings.
NOTE: In order to modify ASR settings you must set read/write access to SNMP community
strings. For more information, see the HP Insight Manager User Guide.
