I'd like each notable event that is raised in ES to have a unique "ticket number" style reference, automatically incrementing as events are raised - along the same kind of lines as ticket reference numbers that are created in systems like ServiceNow when a ticket is raised.
I appreciate that the event_id field is a unique reference for each notable but it's not user friendly enough to be used as a point of reference between multiple analysts
Is there a way to achieve what I am looking for?
You could build a lookup process, which would link the event_id to a more user-friendly ticket number. I am sure that it could be automated with a python script, or some other form of scripting.
For now, I would check out the "Share Notable Event" action in the Actions dropdown per notable event. This produces direct hyperlinks to the notable event with a copy-clipboard option. While not a "ticket number", this link can be distributed in digital-friendly ways:
