Reporting system characteristics

This information describes the following ways to report system characteristics:
  • Using ISGQUERY and GQSCAN to obtain resource usage reports
  • Using SRM to obtain subsystem measurement reports
  • Using IEAMRMF3 to obtain information about the dispatchability of address spaces
  • Using an installation-written component trace to obtain information about component events.

ISGQUERY is the IBM® recommended replacement for the GQSCAN service.
