1. BPEL sensors pushed to a custom JMS queue will not show up on the console.
2. Composite sensors show up on the console (composite sensors are saved to the database by default, and you have no ability to modify that).
3. Database sensor actions show up on the console.
Referring to section 17.3 in the Oracle Fusion Middleware Developer's Guide, it states:
Only sensors with an associated database sensor action are displayed in Oracle Enterprise Manager Fusion Middleware Control Console. Sensors associated with a JMS queue, JMS topic, remote JMS, or custom sensor action are not displayedThat is the reason some of your sensors don't show up in the console.
