Hi,
I have list for 24 hour period:
PC1
PC2
PC3
PC4

I have list for 1 hour period:
PC3
PC4

as result I will receive such list:
PC1
PC2

Do someone know how to do this?

Hi, it looks like you are trying to get the difference of the aggregations. There aren't any features like that in the Elastic stack that wouldn't involve client operations to calculate the difference.

Ok, do some one has any proposal how to solve this question in Kibana or ElasticSearch?

Hi again. I'm not sure why I didn't think of it before, but please take a look at Kibana Canvas.

It has a realm of functions for modeling data before rendering. Also, it has functions for controlling the rendering, which makes it look beautiful.

The documentation on Canvas functions is here: https://www.elastic.co/guide/en/kibana/current/canvas-function-reference.html
