Data table Visualisation not showing correct result for numeric data

Elastic Stack Kibana
1

I am working with Cloudflare analytics data and trying to create a data table visualization to show the sum of the bandwidth in descending order for fields bandwidth.ssl.encrypted, bandwidth.ssl.unencrypted, bandwidth.ssl_protocol.TLSv1.2, bandwidth.ssl_protocol.TLSv1.3, bandwidth.ssl_protocol.none . As a result, I should get a total of all these mentioned fields however, I am getting the wrong data in the visualization.

Following is my logs sample data:

My visualization settings are as follow :

The visualization result is showing in the below screenshot:

It seems like you think that you've configured one thing, but what you've actually configured is not the same thing. You are using arrays of objects in Elasticsearch, and these don't work the way you expect. Kibana also doesn't support the "nested" mapping type which is a common workaround for this issue.

Here's what I would recommend instead. You seem to want the "total bandwidth per protocol". What you should do is create a separate document per protocol.

3

Do you mean a separate bucket for each protocol?

4

No, I'm saying that you have a choice:

  1. To use the built-in Kibana visualizations, you need to change the way your documents are stored in Elasticsearch

  2. If you don't change the documents, then you can only use Vega

5

In case I use built-in Kibana visualizations, what changes I would require to do?

6

The problem here is that you're using filters, which seem to match the entire document. So to use filters you need to have multiple documents that share the same field. For example:

{ id: 1, type: 'TLSv1.3', bandwidth: 10000 }
{ id: 2, type: 'TLSv1.2', bandwidth: 91992929 }

Then you could use filters to get a different value for each type

Thanks.
