【Prerequisites】  
・There are hundreds of servers  
・The disk size for each server has already been acquired

【What i want to realize】  
・Get the disk size difference between the previous day and the current day  
・Display top10 of servers with large (increased) differences among acquired differences

【environment】  
KIBANA:Version: 6.6.1

Perhaps it is necessary to realize timelion, but I can not find a valid writing method

Hi @nakar-kashi. Perhaps you can do this with bucket script aggregations in TSVB. Here's an example screenshot where I've calculated the minimum and maximum value of a field then subtracted to get the difference.

Hi,@nickpeihl.

Thank you for answering.  
Sorry for the missing information.I can get the difference with your answer.

The disk size is taken once every day for each server, and I want to obtain the difference from the previous day on the same server  
Therefore, it is necessary to access the data one day ago.  
I think that timeshift is necessary for realization, but can it be realized with Bucket Script?  
Furthermore, I want to display top10 with a large difference in disk size

for example(For top3 display)

Octorber 1  
serverA:100GB  
serverB:200GB  
serverC:150GB  
serverD:300GB  
serverE:400GB  
serverF:320GB  
serverG:800GB

Octorber 2  
serverA:180GB  
serverB:210GB  
serverC:110GB  
serverD:390GB  
serverE:600GB  
serverF:320GB  
serverG:650GB

DISPLAY  
ServerE 200GB  
ServerD:90GB  
ServerA:80GB
