Using Measure
PROCESS Entity
The PROCESS entity reports processor use and data sent and received by the Expand
line-handler process. It also reports the messages sent and received between the
Expand line-handler process and the applications it is serving. Although the data
counts do not include all the overhead of the lower layers, they do include the NonStop
operating system and Expand headers and any compression words.
Example 19-4 on page 19-26 shows that $B30S received 33 Kbytes per second and
sent approximately 35 Kbytes after adding framing bytes. $B30S was busy 31.20
percent of the measured time and was dispatched 48.13 times per second. Messages-
Sent and Messages-Received show the number of frames sent and acknowledgments
received from the NAM process per second. (Relevant information is highlighted in
boldface type.)

Note. The Cpu-Busy-Time counter does not include all the processor resources used by the
Expand line-handler process. To more precisely determine processor use of an Expand line-
handler process, you must use values provided by both the PROCESS and CPU entity
displays. Using the PROCESS and CPU entity displays to determine processor use is
explained in
Determining Processor Use on page 19-27.
