BMC AMI Strobe overview

Strobe is a software product that reports on how your application programs use resources in IBM z/OS environments. It determines where and how an online or batch application spends time. Incorporating Strobe measurement into each phase of the application life cycle-design and development; build, test and quality assurance; production; and maintenance-ensures that your applications are designed to run efficiently and responsively and that no performance problems are unintentionally introduced.

Strobe employs a sampling technique that executes within the Strobe Measurement Services Address Space (MSAS) and periodically takes snapshots of an application's execution. Strobe stores this data in a sample data set, and organizes the information to produce the Strobe Performance Profile, a hierarchical series of reports that show where and how time was spent during the application's execution. The Performance Profile can indicate which few lines of code, among perhaps thousands, are using significant amounts of system resources. With this focus, you can examine your coding techniques and make changes to only those areas of code that have a major effect on performance.

Users drive Strobe requests either through a modern graphical user interface provided by iStrobe,Workbench for Eclipse, or through classic character-based 3270 screens.
