Abstract
What goes on inside the mainframe doesn’t have to be a mystery. See
how you can more quickly remediate performance issues for complex
mobile-to-mainframe applications with easy to use dashboards and in-
depth tools to detect and analyze performance issues down to the code,
function and database call level.

Application Performance Monitoring
End-to-End application
performance
monitoring based on
CA APM.
This is the CA APM
Team Center view of
the application
architecture.

Mobile to Mainframe
When the system
identifies a slow down,
alerts are sent to
CA APM Team Center.
In this case, you can
see the mainframe
problem.

Mobile to Mainframe
Mainframe Alerts
When an issue is identified in CA APM, you can start by looking at the CICS Alerts panel.
You can see here that it’s exceeding CPU and LIFETIME thresholds.

Mobile to Mainframe
Mainframe Alerts
Drilling deeper from the CICS alerts panel allows you to see the CSMI transaction is in fact causing
the current issue.

Mobile to Mainframe
Historical Data View
Looking at the historical data available within CA SYSVIEW, you can isolate the CICS transaction(s)
you’re interested in. This is useful for comparing past and current performance tests.

Mobile to Mainframe
Historical
drill-down provides
additional
information about
this transaction

Automatically Invoke CA MAT Monitor
Using CA SYSVIEW
Threshold and Event
Capture functionality
to automatically
invoke a CA MAT
monitor

Mobile to Mainframe
The transaction runs again, the CA SYSVIEW threshold is breached which executes the Event
Capture member to invoke CA MAT.
Logging into CA MAT allows you to see the monitor definitions and begin the analysis.

Mobile to Mainframe
CA MAT monitor overview section will tell you if you have a good measurement – was there
actually workload happening during and are there enough samples?
If so, looking at the DelayView pictured here we see the majority of the samples are in program
active. This is essentially the execution of application programs.

Mobile to Mainframe
Looking next at the Code View panel we see almost 72% for module EGUIXVDX and 28% for
DFHEIDTI, the CICS date/time routine.
We can drill down into this module to show the histogram showing the distribution of
code usage.

Mobile to Mainframe
Code level Diagnostics
Since we have
registered the
compile listing we
are able to see the
actual statement
numbers and verbs
instead of only
offsets.
This information is
passed to the
developers to
review and correct.
