Running a process, elasticsearch gets events from TransactionalPersistenceEventManager, but some steps running the process are executed by TriggerUpdateTransactionSynchronization which is a drools manager, not aware of event emitters integration.

Sharing two examples that miss some events:

 

subprocess:

process with HT and subprocess, parent event and task are captured by event emitters, subprocess are missed:

here parent process calling subprocess. Subproces is captured but parent process is missed:

 

To detect missing parameters, enable org.apache and filter by:

grep http-outgoing server.log | grep _index
