How to Display Results in Table that are "Intersection" of two Queries?

Hi all,

we have the following use case:

We have an index containing logs of authentications from different devices. The data looks something like this:

device_id region_id district_id
1234 A district-1
5678 A district-3
1234 B district-5
9876 B district-2
9876 A district-5
1234 B district-6
9876 C district-8

Now we want to display the devices that have authenticated in BOTH regions "A" and "B" and also see the respective districts on a Kibana Dashboard.

Basically something like this:

device_id region_id disctrict_ids
1234 A district-1
1234 B district-5, district-6
9876 A district-5
9876 B district-2

Alternatively, it might also be sufficient for us to filter for all logs about devices that have authenticated in BOTH regions "A" and "B", like this:

device_id region_id district_id
1234 A district-1
1234 B district-5
1234 B district-6
9876 B district-2
9876 A district-5

We haven't found any solution to this yet. We also thought about using vega or transforms but did not really get ahead with this.

Thank you!

Anyone any idea? :slightly_smiling_face: If I can provide any more information, please let me know.

Are you interested in the device_ids who authenticated to multiple regions or also the district_id they authenticated into?

Because as for the former I think you can build a table in Lens using the Collapse by feature over a region_id dimension to have something like:

device_id | count_over_regions
1234      |        2
9876      |        2
5678      |        1

I think with Vega it would be possible to build something more specific, but it take way more effort. Knowing exactly what you need would help to share the answer here.

Thank you for your reply, @Marco_Liberati !

We are interested in both the device_id s who authenticated to multiple regions AND the district_id they authenticated into. I have included two tables how that could look like in my initial question. Option A) is one row per device_id and region_id and showing all district_id s as an array. Option B) is basically one row per device_id, region_id and district_id.

Regarding collapse by:

This feature does not seem to be available yet in 7.16 which is the version we're currently using - sorry for not mentioning the version in my initial question.

We're planning to migrate to 8.x in the near future but I am not sure if collapse by will work anyways for our use case (e.g. it only seems to work for numeric fields). But I will keep this in the back of my head.

Regarding Vega: Can you give me a hint how that could be implemented in Vega? I have read that Vega does not support tables and am not sure how to display the required information in any other format.
