Before imploring IBM to add new function to an already deprecated SMF collection mechanism, I suggest giving SMF logger a try. Even with limited coupling facility resources, you can set up DASD-only log streams--although I have no experience with these. SMF logger is not bullet proof, but it's more resilient in episodes of high usage. And this situation no longer occurs:
All MANx datasets have somehow been marked closed while only partially full, sometimes only a few percent. At IPL time, SMF warns that no data sets are available and begins buffering. That warning can easily get lost in the cacophony of messages issued during IPL. Depending on your tape technology, you may not be able to offload even a single MANx before you start losing data. SMF logger, which can get flooded as well, is much less susceptible to a 'full' condition and loss of data. . . .

Another Check that could be reported is if the last SMF Dataset is the active one (ie: All the others needs to be dumped since there is no empty dataset to be rolled over to). ---------------------------------------------------------------------- SMF is already telling you when this is the case and you could/should have automated this message. In my opinion, this not an unhealthy system configuration situation for HC to report. Besides, catching these events requires almost a realtime monitor, which HC is not.
