Jan, None of the reports you listed will show CPU consumption by program, because that information is not collected. Reported usage for a program will be the same whether it consumed a CPU minute or a CPU hour. Now, the reported usage will be different if that CPU minute (or hour) is spread over one invocation or one thousand invocations, but only in terms of use count. If those thousand invocations are from the one job, then that only counts as one job using the program. This is the sort of situation where the choice of report may become significant. [Note that the above is based Dorana/TAD4z whereas I will not attest to how usage reported by TLCMz is affected by these illustrative comparisons. It is possible that it is slightly different in terms of usage counts.] You're right that Dorana/TLCMz/TAD4z will report the use of programs even if they are not named on EXEC JCL statements. LLA exits can also do this, but only for programs fetched from LLA-managed libraries. I was thinking of a scheme of monitoring CPU time at the RB level back in the Dorana days if there was any interest. There wasn't. The idea was that the CPU time of an RB would be accumulated and logged against the name of the program that the RB pointed to. Note this this means that CPU time spent in programs that were simply branched to would be logged against the programs that branched to them. The scheme would have been strictly for TCB mode only, and so these days may be considered incomplete, and therefore misleading to some extent. Still, it never got beyond the idea stage, so I guess the technical issues are not a problem.
