Index size growth

I am trying to figure out how best to plan for disk space/EBS volume size for AWS ES.

When I get the weekly index details back like this:


Does this mean week .44 has 2.3GB + 25.2GB + new 116GB = for total 168GB?
So weekly data growth for this index is 2GB, then 48GB and then 116GB?

I am trying to understand because I have another index where week .43 is less than the other 2 weeks and I don't understand how that could be!


Each row is a separate index, and each index's size here reflects only the data in that week, not a cumulative sum.

You have three indices:

  1. filebeat-test-2018.42 that has approximately 1.1gb of data with one replica, for a total of 2.3gb in that index.
  2. filebeat-test-2018.32 that has approximately 25.2gb of data with one replica, for a total of 50.4gb in that index.
  3. filebeat-test-2018.43 that has approximately 84.1gb of data with one replica, for a total of 168.2gb in that index.

So the total amount of storage being consumed on this by these three indices, is 2.3gb + 50.4gb + 168.2gb = 220.9gb.

The size of each index just depends on how much log data was produced that week.

Does that help at all?

As an aside, I recommend Elastic's Elasticsearch Service for running Elasticsearch in AWS .
