Enhanced monitoring of VSAM RLS activity using z/OSMF interface

Whenever there is a need to check SMSVSAM health for contention, locks response times and record queues one has to rely upon console commands usually routed to all the LPARs that run RLS workload in order to have a big picture of what is going on. It would be nice to have an interface exploring z/OS MF consolidating SMSVSAM data, this would likely make it  easier to spot problems and act upon them faster, maybe even creating a more user friendly monitoring environment.

    To make it easier to spot problems and act upon them faster, and maybe creating a more user-friendly monitoring environment, the RFE mentions the need to check the consolidated SMSVSAM data to monitor SMSVSAM health for contention, locks response times and record queues. The RFE says "it would be nice to have an interface exploring z/OS MF consolidating SMSVSAM data."

    VSAM RLS (SMSVSAM) has been relying on the Real Time Diagnosis (RTD) component of z/OS for consolidating RLS serialization-related resources which include ENQs and GRS latches. We think it makes more sense to work with RTD than starting something new with z/OSMF, because RTD is already capable of monitoring the ENQs and GRS latches and some other resource contentions. By "record queues", did you mean record lock contentions? Besides "lock response times and record queues", please tell us specifically the resource contentions that you are interested. RTD may be able to be enhanced to monitor them if RTD is not already doing it.
