HP GlancePlus User's Manual (for MPE/iX Systems)
Global Screen
This screen summarizes activity systemwide and lists all processes that
exceed the usage thresholds for the system (figure 5-1). The Global
screen is the first screen to appear when you start GlancePlus, unless
you have specified an INFO string in the RUN command to call up another
screen (see chapter 7).
This Global screen is the usual starting point for a review of system
activity and performance. The information on this screen will tell you
if a resource is used excessively or a process is monopolizing available
resources.

Interesting Processes
Only processes that you define as interesting are displayed on the Global
screen. This allows you to concentrate on processes most likely to
affect performance. A process can be interesting if it exceeds a
user-defined threshold value, it was just created, or it was terminated
during the last interval.
Interesting processes are scrolled down as new entries are added. This
keeps the latest information at the top of the list below the Global
bars. You can scroll the terminal display to examine previous processes
and intervals again. A blank line separates each group of process
information from the group that was displayed during the previous time
interval.

Figure 5-2. Global Screen--Interesting Processes
Some interesting processes will have highlighted fields to indicate an
event that might require closer attention. These appear in a different
color or are underlined on your screen, depending on the type of monitor
(see figure 5-2 for examples of highlighted processes).
You can use the Set Option Values (V) command to change the threshold
values of events to cause a process to become interesting or have one of
its fields highlighted. You can also change the threshold values before
entering GlancePlus by setting the appropriate job control words (JCWs).
See chapter 7 for more information on customizing GlancePlus.
Interesting Process Components
Each interesting process occupies a single line on the Global screen.
The components of interesting processes and any applicable reasons for
highlighting are as follows:
JSNO JSNO is the job number (#Jnnnn), session number
(#Snnnn) or process identification number
(#Pnnn) for the process.
DEV DEV is the logical device number for a job or
session. If the job or session is a system
process, DEV is displayed as SYS.
LOGON LOGON is the first 22 characters of the logon
string (jobsessionname,user.account).
PIN PIN is the process identification number for the
process.
PROGRAM PROGRAM refers to the name of the program being
run. If the program is the MPE/iX Command
Interpreter (CI), then this field displays a
colon (:) followed by the first characters of
the last CI command issued. However, depending
on your assigned capabilities, the following
might apply:
* SM (System Manager) capability will show
the last CI command for all users
systemwide.
* AM (Account Manager) capability will show
the last CI command for all users within
that account.
* A user with neither SM nor AM
capabilities will be shown only his or
her last CI command. All other Command
Interpreters will show CI as the program
name.
The program name of a new process is
highlighted, and an asterisk (*) is located
between the PIN and PROGRAM columns.
A terminating process is represented by the word
DIED, highlighted in the priority (PRI) field.
PRI PRI is the execution queue (where: A=AS, B=BS,
C=CS, D=DS, E=ES) followed by the current
execution priority number of the process
(1-255). If a process has just terminated, this
field will contain the word DIED.
Table 5-0. (cont.)
CPU% CPU% is the percentage of the central processing
unit used by this process during the last
interval.
The CPU field is highlighted if the process
exceeds the CPU threshold. The default is 10
percent of the CPU.
DISC DISC is the disc transfer rate (transfers per
second) for this process during the last
interval.
The DISC field is highlighted if the process
exceeds the disc transfer threshold. The
default is 10 disc transfers per second.
TRN TRN is the rate per minute at which the Return
or Enter key was pressed during the last
interval. Transactions with think times less
than 0. 2 second are not counted since they
probably represent hardware status replies. The
number of transactions is 0 for most batch jobs
because generally they do not read from
terminals.
The TRN field is highlighted if the process
exceeds the terminal transaction threshold. The
default is 10 transactions per minute.
RESP RESP is the average time from when the Return or
Enter key is pressed until the computer is ready
to accept more input. This includes the time
for the process to do all the work requested by
the user, write out all the characters in
response to the request, and issue the next read
to the terminal. This number is 0.0 if there
were no transactions during the last interval.
The RESP field is highlighted if the response
time exceeds the response time threshold. The
default is 5.0 seconds.
WAIT WAIT is the reason a process was waiting at the
end of the last interval.
For a list of WAIT reasons, see table 5-1 and
appendix B, "Wait Reasons--Expanded
Definitions."
