We were recently asked to collect raw monitor data for IBM, because they saw things in one of our z/VM 5.2.0 dumps that surprised them. It took ou r current performance group a week to correctly collect the data. (I'm not
in the performance group any more!) I think it is wise to know how to do this, and test it once in a while. As someone else pointed out, taking a sample before and after a big change could be really valuable if you have a performance problem. Even for an abend, IBM may ask you for performance data.
