Processes
This section displays the following information about all running processes:
• Image—Filename.exe of each process
• PID—Process ID of each process, which can be used to identify the process in Task Manager, other tools, or even the command line
• Hard Faults/sec—Number of instances per second when information has be retrieve from disk based virtual memory rather than RAM
• Commit (KB)—Total amount of memory (physical and virtual) committed to a process
• Working Set (KB)—Total amount of physical memory (shareable and private) committed to a process
• Shareable (KB)—Total amount of physical memory committed to a process (shareable by another process)
• Private (KB)—Total amount of physical memory committed to a process (not shareable by another process)
Physical Memory
A variety of system statistics about memory usage are displayed in this section:
• Hardware Reserved—Total memory reserved by various hardware devices on the server
• In Use—Total current physical memory used
• Modified—Modified pages that have not yet been released
• Standby—Cached data that is not actively in use, but readily available if called
• Free—Total physical memory that is available, but not in use, modified, or in standby
• Available—Total physical memory that is available, including in use, modified, or in standby
• Cached—Modified and standby combined
Why is this information useful? Persistent
high numbers in the Hard Faults/sec column suggests a need for
additional physical RAM. However, if the amount of cached memory is
high, but the hard faults remain low, applications may very well be
designed to cache a high percentage of free memory for better
performance.
Disk Tab
The Disk tab provides disk-related
information about Processes with Disk Activity, Disk Activity, and
Storage sections. After taking a look at this tab in Figure 8, let’s review the details behind each section and the information it provides.
