- We track the usage (but not the resources) of certain products by
- intercepting SVC 202/204and SMSGing a SVM which records the invocation
- of the tracked commands. We do this with a CMS nucleus extension which
- enables itself as a FLIH and calls DMSITS as a 2ndLIH. We don't get
- any resource stats (i.e. CPU usage) doing things this way but we have
- no need for that level of detail at present as we do not use this
- facility for chargeback ... merely to audit if costly products are truly
- needed and used by our users. As a result, we can live with the
- fact that the NUCEXT is volatile (as opposed to BALRing to our code as an
- exit from DMSITS itself).

- One of my old shops used VMACCT for tracking certain program product
- resource usage .... one disadvantage at that time (mid 80's) was that
- we were required to re-build the executable MODULES we wanted to track
- to use the VMACCT code as their maint entry-pt. Don't know if things
- are any cleaner today. The advantage was that it did cut CP accounting
- records which were easily rolled into our standard accounting reports.
