Elastic Usage Disk Filtered By Date

Elastic Stack Elasticsearch
1

I have an Elasticsearch cluster and want to know the memory usage of all indices over the past 3 months. This way, I can request additional resources using accurate data.

I am using the command /_cat/indices?v, which provides usage data from the beginning until today. How can I filter it to show only the last 3 months?

hi @zerratriani

No simple real simple way to do that...
Depending how your indices / data streams are broken up... that could make it easier, but I think you will need to estimate avg doc size per index then multiple that by the number of estimated docs over that time frame.

Apologies I wish this was easier...
