DPA 12.1.7 Showing CPU mismatch information OS CPU utilization is low compared to Instance CPU utilization.
This is a problem with 12.1 that occurs typically when there is a high number of cores. The problem has been fixed in the latest release DPA 2019.4. There are some workarounds that can be seen in this KB article (Success Center) if you want to stay on 12.1. However, those workarounds have some side effects. So my recommendation would be to upgrade to the 2019.4 release.
