CICS® monitoring and statistics data can be used to help tune FEPI applications, and to control the resources that they use. FEPI statistics contain data about the use of each FEPI pool, a particular target in a pool, and each FEPI connection. The performance aspects of the FEPI are not discussed here -- for information on these, see the CICS Front End Programming Interface User’s Guide.
For listings of FEPI statistics, see the CICS statistics tables in topic Front end programming interface (FEPI) statistics.
