Pinpoint Inefficiencies Causing Excessive CPU Consumption and Elapsed Runtimes

Strobe, Compuware’s performance management and analysis solution for mainframe applications, lets performance analysts pinpoint application inefficiencies causing excessive CPU consumption and elongated elapsed times to reduce hardware and software costs.

With Strobe, mainframe teams can:

  • Locate and improve resource-consumptive database calls
  • Identify tuning opportunities to reduce monthly software licensing costs (MLC)
  • Resolve performance issues before they impact application service levels
  • Apply analytics to captured data to produce reports showing high-resource consumption and applications that need tuning
  • Measure activity of both online and batch-processing applications in single and multiple- system environments
  • Identify several I/O problems, including inefficient VSAM file buffering
  • Create and schedule automatic, reusable measurements
  • Automatically detect performance problems by using a rolling average of CPU consumption and elapsed-time metrics

The Value of Strobe

  • Improves user code efficiency, transaction response time and throughput
  • Enables new users to be more productive using a graphical interface
  • Reduces complexity of mainframe application performance management
  • Reduces time and resource consumption

Integrates with industry-leading tools from BMCConicIT, AppDynamics and Dynatrace

Key Features of Strobe

Expose Hidden Performance Issues

Using iStrobe, a browser-based Strobe reporting and analytics interface, performance analysts can identify and view:

  • Program statements consuming excessive CPU resources
  • Percentage of CPU time used within modules and control sections
  • Procedure names and statement numbers
  • Complete lines of source code

DB2 SQL Strobe Advisor

Strobe Advisor, accessible via iStrobe, enables performance analysts to:

  • Identify access paths used by SQL statements and relevant catalog statistics
  • Perform “What If” analysis, making changes to SQL statements to see if they affect Db2 access paths
  • Determine what causes excessive CPU and/or wait time
  • Receive catalog statistics and the number of GET PAGE requests for each SQL statement

CICSPlex Reporting

CICSPlex reporting allows performance analysts to aggregate data from multiple CICS measurements into a single iStrobe report.

IMS Transaction Profiling

With IMS Transaction Profiling via Strobe Advisor in iStrobe, performance analysts can:

  • Capture data on all transactions regardless of the region they execute in
  • Receive performance data on all IMS transactions whether or not they are executed in the measured MPR
  • Identify the modules in an IMS preload list and determine if there was activity with them, allowing the analyst to optimize the IMS Preload list and avoid a short-on-storage situation

Strobe Insight Built-in Analytics

Strobe Insight via iStrobe allows performance analysts to:

  • Execute reports to find problems across profiles
  • Query SMF data to determine what jobs should be measured
  • View analysis for all major subsystem components

Rolling 4-hour Average (R4HA) Reporting

Glean insight into your R4HA MSU usage with Strobe Insight soft capacity peak time reporting. Using SMF data, Strobe identifies the peak period and exactly what was executed during that time regardless of LPAR. Data is collected in Coordinated Universal Time (UTC) instead of current local time, enabling analysts to collect more accurate measurements and focus on tuning jobs that can result in lower licensing charges.

AutoStrobe with Global Batch Monitoring

AutoStrobe boosts productivity and increases the flexibility of Strobe and iStrobe by making the measurement process predictable and repeatable. AutoStrobe includes Global Batch Monitoring, a feature that automates the detection of performance problems by using a rolling average of CPU consumption and elapsed time metrics.

Strobe Integrations

Through an integration with Strobe and ThruPut Manager, developers can use a ThruPut Manager JCL Card in a batch job to quickly start a Strobe measurement on a jobstep(s). At the termination of the measurement, Strobe will automatically create an iStrobe Profile and send an email to the user with a link to that Profile.
