At the behest of Sam Knutson and the SHARE MVSE Project, I delved into SMF
with logger in time to pull together a user pitch in Orlando: Session 2850
, where I tout virtues and expose warts, which IBM informally acknowledge
but as yet have no specific solutions to announce. The pitch includes
references to an IBM session on the subject presented first in San Diego
and repeated in Orlando. Also pointers to some manuals I consulted.
One problem I noted with managing Logger for SMF is the large amount of
DASD space that could be tied up to contain just one day's worth of data.
(System Logger retains data for a minimum of one day.) It was pointed out
to me after my session that offload data sets can be migrated. I had read
that comment in the doc but never pursued how it would work in practice.
SMF data can be offloaded as often as you choose. I wrote a Rexx that dumps
data to tape (for example) as often as once an hour. The trouble with the
Logger implementation is that dumped data is not 'marked'. The only way to
avoid dumping the same data over and over is to adjust the start/end values
in IFASMFDL. In any case, the data lives on until System Logger expires it.
Nonetheless, I believe that SMF with Logger provides enough benefit to make
it worth the exercise.

The current complaints are you do not clear the logstream. A problem for
shops that do not IPL for months on end. I have not heard of anyone
forcibly
reming logstreams, System Logger rules!
