Customizing GlancePlus Global Bars 

As discussed in chapter 3, the Global CPU bar and the Global Memory bar
can be configured differently.  This will change the abbreviations and
their corresponding components in those bars.

For example, you can reconfigure the components of the Global CPU bar to
show activity by queue and the components of the Global Memory bar to
show fault rates, as discussed below.

Global CPU Bar 

Reconfiguring Global CPU Bar to show activity by queue is useful when you
use a batch job to initiate processes that interact with terminal users.
The normal "interactive/batch" representation would show these terminal
users as "batch" since they were initiated as a batch job--this would not
be as useful as a queue representation.  A queue representation might
also be useful on a system where interactive sessions and batch jobs
routinely execute in queues other than the normal CS queue for sessions
and DS and ES queues for batch.

The CPU bar has the following components:

DISPCPU = QUEUE

                   Code                     Meaning 

                     M                      MPE processing (memory management,
                                            interrupts, ICS, etc.).

                     A                      Processes running in the A subqueue (system
                                            priority).

                     B                      Processes running in the B subqueue (high
                                            priority).

                     C                      Processes running in the C subqueue
                                            (normally interactive).

                     D                      Processes running in the D subqueue
                                            (normally batch priority).

                     E                      Processes running in the E subqueue
                                            (normally background).

                     P                      Paused for disc (no CPU used but disc I/O
                                            is occurring).

                   Blank                    CPU was idle (and no disc I/O was
                                            occurring).

Global Memory Bar 

Configuring the Global Memory bar to show page-fault rates rather than
contents might be useful on a system where memory is a bottleneck and
page faults are used as key indicators to alert you of a problem.

The Memory bar has the following components:

DISPMEMORY=FAULTS (Page fault rate for different object types) 

                   Code                     Meaning 

                     T                      Transient objects (program heaps, etc.).

                     P                      Permanent objects (not normally faulted).

                     S                      Data Stacks (NM + CM).

                     C                      Code (NM + CM).

                     D                      Data objects.

                     F                      Files.

                     L                      Library code (NM + CM).
