Can't sum up the values with top_hits aggragation

[yjaigu]

Hi,

in Kibana 7.11.2 and kibana-enhanced-table v1.11.1, it doesn't sum up the values in a top_hit metric, aggregated with "concatenate" (with a simple split row bucket). Only "count" is actually working as a total function. It is annoying since I use the total of these columns to compute other colums total.

Example :

• Metric
  • aggregation : top hit
  • field : a_numeric_field
  • aggregate with : Concatenate
  • Size : 1
  • Sort on : @timestamp
  • Order : descending
• Split rows :
  • aggregation : terms
  • field : a_string_field
  • order by : alphabetical
  • order : descending
  • size : 5
• Options :
  • Show total : checked

Indeed, I reproduce the issue. I will try to fix it in next release.

thanks Fabien !

Hi @fbaligand ,

This is still an issue in Opensearch 2.2.0.

I'm unable to sum Top hit aggregations whereas I'm able to do so in data table.

Data table:

Enhanced table:

Need your help.

[fbaligand]

Well, I just did some tests, and I'm able to make it work: if field is numeric, and you use Average, Max, Min or Sum in "Aggregate with" setting, then Total feature works.

@yjaigu @Sandy381 Could you try to use Average, Max, Min or Sum in “Aggregate with” setting?

[Sandy381]

It works with Max, Min & Sum aggregations. No issues. For now I'm using Sum for my visualization & then put control filter visualization on top of my table visualization and filter as i need. But in some cases, I may want latest values. In this case it will not add up. Thanks for checking :)

[fbaligand]

Well, in "Top Hit" metric, if you set 1 in Size setting, whatever you use Average, Max, Min Sum or Concatenate aggregation, you will get exactly the same displayed result. Moreover, I just tested Data Table with a "Top Hit" metric with size=2 and Aggregate with=Concatenate. The total (sum) is the value of the first item, so it is wrong. It should be the sum of both items.

Demonstration with Data Table:

Hi Fabien, have you implemented the solution for this issue? I have the similar requirement . I am trying to create a metric visualization where I want to sum the top hits on an aggregation. I am using Kibana version 7.17 but I don't see the top hit option in 8.10 as well if I select bucket aggregation.

[fbaligand]

Hi, « top hit » aggregation is a « metric » aggregation, so you can’t use it in « bucket » aggregations. Then, as explained in previous comments, if you use top hit aggregation with size=1 and function=max, then the « total » feature will work.

If it still not works for you, could you share your settings as initial description does (or share your settings screenshot) ?
