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 of the overhead of the lower layers, they do include the
NonStop™ Kernel and Expand headers and any compression words.
Example 20-4 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 20-27.
