Memory

The memory object provides information about the usage of physical memory and swap memory on the
server.

Counter Descriptions
This counter represents the number of IP reassembly failures that the IP
reassembly algorithm detected, including time outs, errors, and so on. This
counter does not represent the discarded IP fragments because some algorithms,
such as the algorithm in RFC 815, can lose track of the number of fragments
because it combines them as they are received.
This counter represents the number of IP datagrams that were successfully
reassembled.
This counter represents the number of IP fragments that were received that
required reassembly at this entity.
Table 5-51 contains information on memory counters.
Counter Descriptions
This counter displays the system physical memory utilization as a percentage. The
value of this counter equals (Total KBytes - Free KBytes - Buffers KBytes -
Cached KBytes + Shared KBytes) / Total KBytes, which also corresponds to the
Used KBytes/Total KBytes.
This counter represents the percentage of active pages.
This counter displays the system virtual memory utilization as a percentage. The
value of this counter equals (Total KBytes - Free KBytes - Buffers KBytes -
Cached KBytes + Shared KBytes + Used Swap KBytes) / (Total KBytes + Total
Swap KBytes), which also corresponds to Used VM KBytes/Total VM KBytes.
This counter represents the capacity of buffers in your system in kilobytes.
This counter represents the amount of cached memory in kilobytes.
This counter represents the total amount of memory that is available in your
system in kilobytes.
This counter represents the amount of free swap space that is available in your
system in kilobytes.
This counter represents the number of page faults (both major and minor) that the
system made per second (post 2.5 kernels only). This does not necessarily
represent a count of page faults that generate I/O because some page faults can get
resolved without I/O.
This counter represents the total low (non-paged) memory for kernel.
This counter represents the total free low (non-paged) memory for kernel.
This counter represents the number of major faults that the system has made per
second that have required loading a memory page from disk (post 2.5 kernels
only).
This counter represents the number of pages that the system paged in from the
disk plus the number of pages that the system paged out to the disk.
