Symptoms

After upgrading the EM Agent to 12.1.0.3 and/or the corresponding database plugin, collection of some metrics stops, although they show as enabled from Enterprise Manager 12c Cloud Control.

The affected metrics are those which are disabled by default at installation, but were later enabled at some point in time prior to upgrade.
