Eight ‘Hidden Gems’ You Should Be Using in Compuware iStrobe
Achieving good performance has always been a major focus for mainframe teams, but it’s even more so today as mainframe applications and data increasingly feed into customer-facing web and mobile applications. Modern mainframe DevOps teams know tools like iStrobe—the browser-based reporting and analytics interface for Compuware Strobe—are essential for maintaining high throughput and quality. We want you to take advantage of every productivity-boosting aspect of iStrobe you can to ensure you’re continuously improving mainframe application performance. That’s why we’re hosting “Discovering the Hidden Gems of Compuware iStrobe,” the latest webcast in our monthly “Did You Know?” series. Register to see a live demo of useful but often overlooked features and functions of iStrobe.
iStrobe’s Eight Hidden Gems
During the webcast, we’ll explain how to use the following features and functions you may be overlooking when using iStrobe to accomplish your daily application performance management activities. Here, we’ll give you a high-level overview of each.
1. iStrobe Performance Tracker
Performance Tracker in iStrobe allows you to identify opportunities for performance improvements as well as estimate the costs of poor performance and the potential cost savings. An opportunity is a specific instance of poor performance that, when corrected, yields an improvement in the performance of the job.
Opportunities are tracked by profiles that, along with the opportunities identified for each profile, are collected by projects. A project specifies the cost set to be used to calculate costs and savings. When you add a profile to a project via myStrobe, it becomes possible to identify opportunities in your profile.
Expanding the module will position you at the line of code. If you select an opportunity and then the dollar sign in the upper right corner, you can add the opportunity to Performance Tracker. Before adding, you can provide details around the opportunity, such as a description, the type of opportunity it is, what category it belongs to and more.
Once the opportunity is added, you can see details such as the annual cost as well as potential savings annually and per run.
2. iStrobe Issue Tracking
Compuware’s integration with Atlassian JIRA Software enables enterprise developers and operations teams with mainstream skills to include mainframe application issues in their JIRA-based environments. The iStrobe Issue Tracking integration with JIRA can be accessed via Compuware Enterprise Services under the administration function in your iStrobe browser. Here, you can create and configure performance issues to track through JIRA.
Once your issue is configured, you will need to create a JIRA request through myStrobe.
When you submit a fix-request through StrobeAdvisor, it will open a JIRA where your issue can be tracked.
3. iStrobe User Help
User Help, accessed via StrobeAdvisor, allows you to add customized help for modules that can be shared with your team.
When you notice a program isn’t set up with User Help and you have knowledge to share, you can add information made accessible via a hyperlink that will help others when they work with that program. This feature is a great example of how mainframe teams can take advantage of iStrobe to close the skills gap they may be experiencing as experts retire.
4. iStrobe SQL Analysis on Demand
SQL Analysis on Demand, accessed via myStrobe, allows you to obtain Db2 EXPLAIN and catalog statistics. It also allows you to modify SQL statements and request the EXPLAIN data and catalog statistics. For example, if you’re making a change to a WHERE statement to give it a better access path, you can use SQL Analysis on Demand to dynamically explain that statement and see if it made a difference in your access.
5. Comparing Profiles in iStrobe
The Compare function, accessed via myStrobe, gives you the ability to compare two iStrobe profiles simply by holding the control key, selecting two profiles, right-clicking and selecting “Compare.” This positions you at the measurement session data report where you can see from the side-by-side reports how well each program ran. The reports are synchronized and will slide together as you move through them, making it easy to compare information throughout each report.
6. iStrobe Folder Creation
Folder Creation, accessed via myStrobe, is a feature that allows you to create folders used for storing and organizing profiles. By default, all new profiles are placed in a folder named iStrobe unless directed otherwise during profile creation. By simply right-clicking, you can create a new folder for a profile.
7. myStrobe Columns in iStrobe
iStrobe allows you to specify which columns you would like to see on the myStrobe display. This allows you to customize the myStrobe display to meet your needs. To look at which columns can be displayed, simply right-click to “View Columns” and see the various columns you can show on your myStrobe display. You can also rearrange the columns you see displayed.
8. iStrobe Filters, Notes and Tags
Filters allow you to narrow your display. You can filter on several things to trim the display to what you want iStrobe to show for both measurements and profiles.
Notes and tags enable you to add personal comments to a profile. Use notes to document and share performance improvement suggestions amongst your team. Tags can be created with a performance profile, which will show the tags on the display. Tags can also be used for filtering criteria to categorize the type of profile you have.
