Hello, I need to do an unique count of items that are duplicates, let me explain.
We use customer.id , it is unique for every customer. What we would like to visualize is only the customer.id's that are logged more than once in our index.
Tom - Appears once
Jhon - Appears twice
Simon - Appears tree times
We only want to count Jhon and Simon, so the count should be 2 instead of 3.
Is this doable in Kibana or not ?
