Changes from Version B.00.00 to Version B.00.02
The changes and enhancements made to Performance Collection Software
since the B.00.00 release are described here.
Starting with MPE/iX B.40.00 (4.0) and MPE V G.23.00 (23) the Performance
Collection Software can be installed or updated as a normal part of the
MPE update procedure. Using the MPE update procedures should make it
easier to install. Time-consuming uploads from the PC will not be
needed, and you will be less likely to get a mismatch between the
collector and MPE versions.
Changes in SCOPE(XL)
On MPE V, the limit of 628 processes was raised to 1024 on the release 23
MI. SCOPE B.00.02 will allow you to collect performance data on systems
with more than 628 processes.
SCOPEXL B.06.02 now supports MPE/iX release 4.0. This new SCOPEXL
collector was adjusted for all internal changes in the operating system,
and these changes should be transparent to Performance Collection
Software users.
A new Service Level Agreement metric has been added to both MPE V and
MPE/iX versions of SCOPE(XL). This metric measures the percentage of
terminal transactions that were below specified response times.
Different service levels may be set for each application. See appendix B
for more information.
Log file maintenance and roll back procedures can be scheduled to occur
at specified times instead of only when a log file is filled. SCOPE(XL)
will examine each log file once a day. If the program estimates that the
file might become filled within the next 24 hours, it will initiate a
roll back immediately. Refer to the MAINTIME directive for more
information.
A new report can be generated to help identify the users responsible for
disc space usage and to test the DISCGROUP definitions in the Performance
Collection Software PARM file. You may generate this report at any time
by running the SCOPE2 or SCOPEXL2 program and specifying ;INFO="HELP".
Default thresholds have been adjusted:
Threshold Old New
Value Value
MINTHINK 0.1 0.2
WAITCPU 100 50
WAITDISC 100 50
WAITIMPEDE 100 25
WAITMEMORY 100 25
Host Access to Data
A new command, EXPORT, was added to the existing EXTRACT program. This
command will create files containing selected Performance Collection
Software data in formats suitable either for printing or for further
analysis by other programs. By permitting direct access to Performance
Collection Software data on the host HP 3000 system, it will be easier to
do automated and custom reporting of performance data.
Performance Alarms
Historical analysis of existing Performance Collection Software log files
can be performed using the UTILITY program.
Special features added to the UTILITY program allow you to use the
alarm-processing feature to examine the log files in a routine batch job.
Action is taken only when system performance indicates it is necessary.
Changes in EXTRACT and UTILITY
You can specify starting and stopping dates relative to the current date
by using a special TODAY or TODAY-nnn syntax in the START and STOP
commands.
