Last record for each unique value

Hi @JeremyLoyd,
if you're using version 7.12 of Kibana, you could use Lens to create datatable visualization. Otherwise use the normal datatable.

Here's the example chart that might help you. CustomerId is an equivalent of uniqueId, product_name.keyword is an equivalent of event. Let me know if I understood your problem correctly:

  1. Setup your time picker to last 24 hours
  2. Switch to datatable in chart picker on the top of the workspace
  3. You can use top values aggregation on uniqueId and set up number of values really high (more than uniqueIds you're expecting to have)
  4. Configure metric as last value on the event
