What does FreezeFrame do?
FreezeFrame analyzes application performance on z/OS by capturing and reporting on CPU usage, I/O activity, and wait times at the job step, CSECT, and potentially instruction level. It helps identify performance bottlenecks.
How is FreezeFrame configured?
FreezeFrame uses configuration files to define the jobs and steps to be analyzed, as well as the reporting options. These files specify parameters such as sampling intervals and output destinations.
What kind of reports does FreezeFrame generate?
FreezeFrame provides detailed reports on CPU usage, I/O activity, and wait times. These reports can be generated at different levels of granularity, from the job step level down to the CSECT or even instruction level.
What are the main use cases for FreezeFrame?
FreezeFrame can be used to identify performance bottlenecks in z/OS applications, optimize resource utilization, and improve overall system performance. It helps developers and system administrators understand how applications are using system resources.
