For all triggered emails, they utilize the same JobID until you pause and restart them. Generating a unique JobID for every individual triggered send is, pardon my bluntness, quite absurd. If you want to track individual sends, you can check your send log or the data views utilizing the TriggeredSendID and SubscriberKey/SubscriberID
In order to track the journey email sends, you would need to use the _Journey Data View to grab the VersionID of the Journey you want (if you do not already have it) and then use that VersionID to match on VersionID in _JourneyActivity Data View. This will allow you to grab the
JourneyActivityObjectID which will match
TriggererSendDefinitionObjectID in the other data views.
JourneyActivityObjectID corresponds to TriggererSendDefinitionObjectID
in the _Sent, _Open, _Click, _Bounce, and _Unsubscribe data views.
This will then let you create reporting on the Journey emails inside your Journies same as you would with any other Triggered Send Definition.
