Monitor and Profile CICS Transactions and Regions with IntelliMagic Vision
IntelliMagic Vision enables performance analysts to manage and optimize their z/OS CICS regions and transactions more effectively and efficiently, as well as proactively assess the health of their CICS regions.
Built-In Intelligence at Your Fingertips
Proactively Assess Key CICS Region Metrics to Enhance Availability
The CICS statistics 110.2 records contain many metrics that lend themselves to being assessed as part of the overall health of a region. IntelliMagic Vision assesses key metrics across every CICS region against best practice values to identify potential risks to availability that may warrant additional investigation.
The assessments are initially rolled up into user-defined logical groupings of regions and presented in a red/yellow/green manner that can be quickly consumed. From here the user can drill into additional levels of detail, all regions making up the selected group, or into time charts for the metrics.
View CICS Statistics Data at Additional Levels of Detail
Many types of CICS Statistics data can be explored at additional levels of detail, e.g., file name, enqueue name, transaction class, and TCB mode. This image leverages dynamic navigation and context-sensitive drilldowns to determine which CICS storage areas are experiencing Short on Storage conditions.
View Transaction Response Time Profiles
One common starting point for analysis of CICS workloads is a “Top n” view of transactions by total CPU consumption or by transaction volume.
Drill downs from here can quickly focus the analysis on response time profiles, with the nearly 100 timing buckets of the CICS SMF 110.1 records initially grouped into high-level summary categories (as shown here). From there the user can drill into the detailed components of the categories of interest.
Identify Primary Drivers of Transaction Response Times
Once the initial response time display identifies the high-level categories that are primary contributors to response time, dynamic navigation and context-sensitive drilldowns can be leveraged to identify the specific components of interest.
If a primary response time category for a transaction is “Total I/O Wait Time” (as seen in the previous image), its subcomponents can be examined with a single click. Here “Wait for Control at end of MRO” and “Wait for RLS File I/O” are quickly identified as primary response time components.
Elapsed Time Profiles Across Transactions
The ability to compare profiles across transactions by the primary CICS response time categories can also provide helpful insights. This example shows CPU per CICS transaction across the set of top transactions.
Global filters can also be specified to further focus the selected transactions.
Compare Across Time Intervals
Comparisons across multiple time intervals are often of interest when analyzing the impact of the implementation of an application release on CPU per transaction. Throughout the product IntelliMagic Vision enables easy comparisons of values across any two time intervals to facilitate analysis.
In addition, crosshairs corresponding to the mouse position display tooltips with the numeric values for the selected interval, enabling at-a-glance comparison of specific before and after intervals.
Analysis Leveraging Response Time Views
If investigating a response time issue, one may choose to begin from a response time view. From here, analysis seeking to isolate the issue may examine times for the selected transaction across systems and/or regions.
This image displays an example where a specific transaction timing component differs significantly across two sets of systems.
Integrating CICS Transaction with Db2 Data
Capitalizing on the fact that Db2 Accounting data (SMF 101) captures the CICS transaction ID, IntelliMagic Vision seamlessly integrates key metrics from Db2 with the CICS SMF data.
This set of charts integrates metrics from the CICS perspective on the top row (based on the transaction ID) and DB2 perspective on the bottom row (using correlation ID from the Accounting data).
Leveraging Integrated Visibility Across Types of z/OS Data
IntelliMagic Vision delivers integrated visibility across various types of z/OS data to aid CICS and all types of performance analysis. In this scenario, a prior view from Systems data indicates a WLM goal not being met for selected time intervals.
Easy visibility across into CICS data shows increased volumes of a long-running transaction corresponding to the intervals when the WLM goal is being missed.
Analyzing Non-timing Transaction Data Fields
Finally, more than 250 non-timing fields in the CICS 110.1 records are available for detailed analysis and are organized into the subgroups provided in the IBM documentation.
The customized dashboard in this image shows examples of several of these, including Db2 SQL calls per CICS transaction, log stream writes, program loads, and file gets.
