APM not recording table artifact usage

[AmySwinford]

We have Audit and Performance Monitoring installed on our SAS 9.4M4 grid, and depend on it for statistics about usage on our >700 libraries. Until today I thought that every metadata table/view that got accessed was being recorded so I could run a quick report and notify affected users if there was a change. Today I ran a report looking at a specific library and only got a handful of tables being used.  However, I can clearly see (also in APM) that there is a table not in the report results that has been accessed hundreds of times by stored processes over the same time period. Does APM ignore artifacts accessed through sassrv? Or is it possible that sassrv artifacts are listed differently? I thought it would get the meta user and record that user with the artifact, but it isn't in the artifact table at all. Anyone else observe this behavior?

Due to the nature of this question, I believe tech support is your best bet: https://support.sas.com/ctx/supportform/createForm

Good luck!
