What is Service Management Connectors for WebSphere® Studio Application Monitor (WSAM)?
This technology is an add-on for WSAM 3.2 customers. It provides the following new functions:
- Production Eligibility Check (PEC): Using collected performance data, the PEC determines whether an application is production-eligible based on customer-specific performance criteria (such as response time, CPU time, and throughput).
- Performance Regression Test (PRT): PRT compares performance characteristics of a new version of an application versus the current (base-line) version and identifies any changes in production eligibility.
- Initial Configuration Estimate (ICE): Using a combination of collected application performance data, along with customer-specified objectives for performance, ICE determines an optimal hardware configuration that supports these objectives.
These new reports are built using application performance data collected by WSAM, and they provide additional Web-based views of that data in order to facilitate change management and capacity management processes. By using these reports, WSAM customers can better predict the impact of an application change to their stated performance objectives or service levels, and they can better estimate the infrastructure required for supporting these objectives.
How does it work? Once installed, users are provided with a Web-based wizard for generating these new reports. For PEC/PRT reports, they specify the time ranges and server(s) where the performance data has been collected (and typically generated by Rational Performance Tester or a similar load generation tool); then they enter specific target values for key statistics such as response time, throughput, and memory usage. The wizard then generates the report, and quickly shows pass/fail indicators for each of these statistics. If a "fail" condition is encountered, the user can then drill down into a specific report to conduct more detailed analyses and determine the reason for the failed condition.
ICE reports are driven by a similar wizard. Again, users first specify time ranges and servers where the performance data has been collected. They are then asked to specify a variety of performance goals, and finally they are asked a few specifics about their Web infrastructure (platform type, number of tiers, use of SSL, etc.). All this data is then fed into an engine that computes and displays the optimal hardware configuration necessary to support these performance goals. This computational engine is based on OPERA, a utility developed by the HIPOD research group within IBM.
