Currently we can only send alarms to an Alarm Journal on "Display path" or "Alarm Source" which is extremely limiting.
Alarm Source is effectively just based on how you structure your tag provider folders, and Display Path can literally be anything.
We've built lots of filtering on the various alarm components to utilize the alarm associated data properties. These may contain plant location, machine name, tag type etc... and would be a much more flexible way to split out alarms into different journals.
Not all alarms will necessarily have the associated data property configured in the journal, but in that case it generally makes sense to allow us to bring it through or exclude it by default.
Due to the nature of Ignition having tag providers accessible to all projects across the gateway, it would be nice to ensure distinctly different projects have an easier way to include / exclude alarms in their own journals based on properties we choose.
