Network Interface
The network interface object provides information about the network interfaces on the system.
Table 5-52 contains information on network interface counters.
Pages Input This counter represents the number of pages that the system paged in from the
disk.
Pages Input Per Sec This counter represents the total number of kilobytes that the system paged in
from the disk per second.
Pages Output This counter represents the number of pages that the system paged out to the disk.
Pages Output Per Sec This counter represents the total number of kilobytes that the system paged out to
the disk per second.
Shared KBytes This counter represents the amount of shared memory in your system in kilobytes.
Total KBytes This counter represents the total amount of memory in your system in kilobytes.
Total Swap KBytes This counter represents the total amount of swap space in your system in
kilobytes.
Total VM KBytes This counter represents the total amount of system physical and memory and swap
space (Total Total Swap Kbytes) that is in use in your system in
kilobytes.
Used KBytes This counter represents the amount of system physical memory that is in use in
kilobytes. The value of the Used KBytes counter equals Total KBytes minus Free
KBytes minus Buffers KBytes minus Cached KBytes plus Shared KBytes. In a
Linux environment, the Used KBytes value that displays in the top or free
command output equals the difference of Total KBytes and Free KBytes and also
includes the sum of Buffers KBytes and Cached KBytes.
Used Swap KBytes This counter represents the amount of swap space that is in use on your system in
kilobytes.
Used VM KBytes This counter represents the system physical memory and the amount of swap
space that is in use on your system in kilobytes. The value equals Total KBytes -
Free KBytes - Buffers KBytes - Cached Shared Used Swap
KBytes. This corresponds to Used Mem Used Swap KBytes.

Counters Counter Descriptions
Rx Bytes This counter represents the number of bytes, including framing characters, that
were received on the interface.
Rx Dropped This counter represents the number of inbound packets that were chosen to be
discarded even though no errors had been detected. This prevents the packet from
being delivered to a higher layer protocol. Discarding packets to free up buffer
space provides one reason.
