I try to make a ratio between 2 metrics during a period.
1 - sum aggregation of server RAM Used
2 - sum aggregation of server Ram capacity
I did it with TSVB and bucket aggregation and it works but il would like to export these informations in csv so i try to do it with Data Table
TSVB or TimeLion make a such operation for a given date. I would like to do it for a specified duration.
Could you give me tips to do it un DataTable ? In fact if i could use a Bucket aggregation in a Kibana visualisation like DataTable i could fix my problem
