APAR PM04580 introduces Performance Alerts in CICS® Performance
Analyzer for z/OS® V3.1,
and includes the following new features and changes:
- Performance Alerts
- Allow you to compare CICS transaction performance against user-defined
levels of acceptable performance. A Performance Alert Definition specifies
a list of CICS resources to be monitored or managed, together with
thresholds that benchmark expected levels of performance. The reports
apply to CMF data only. You can report Performance Alerts in various
ways:
- By Transaction. The Performance List report has been enhanced
to list all transactions that have triggered one or more alerts. It
can also be an alert-specific report by reporting only those transactions
that generate an alert.
- By Transaction Summary. The Performance Summary report has been
enhanced to provide the total or percentage of transactions that have
triggered alerts.
- Resource Definitions
- Primary menu option 9 now invokes the Resource Definitions menu.
It includes the two options previously available from the Application
Grouping menu which allowed you to define Resource Lists and Application
Groups. A third option has been added to allow you to define Performance
Alerts.
- Copy alert definitions
- You can now copy definitions of Statistics Alerts and Performance
Alerts to the same or another repository.
- Report Forms
- Report Forms have been enhanced to enable Performance Alert reporting
while utilizing the flexibility of Forms. List and Summary Report
Forms now allow the SEV function for alert reporting fields. Existing
List Forms will be automatically upgraded next time you edit them
to include the new Fn (Function) column required for the new alert
SEV function. For SEV fields in the Summary Report Form,
specify the alert severity level, INFO, WARNING or CRITICAL, and report
type COUNT or PERCENT. In addition, the Summary Report Form supports
the new ALERT field name to provide total counts or percentages of
transactions for each alert severity for the summary key.
- Report Sets
- Performance List and Summary report and extract specifications
have been enhanced to include predefined Performance Alerts to work
together with, or instead of, Report Forms.
Also, you can request
an interval-based Performance Summary report or extract to add or
override the Form summary key fields without altering the underlying
Report Form.
- Sample JCL
- Four new JCL members are provided in the CICS PA sample
library, SCPASAMP. The new sample jobs are CPAPALST, CPAPASUM, CPAPAXTL,
and CPAPAXTS to request a List or Summary report or extract using
pre-defined Performance Alerts.
