Daily Indexing (at Midnight)

Elastic Stack Elasticsearch
1

Hi there,

As I understand from this GitHub post and this Elastic Discuss post about having a new daily index (at midnight for my case), the solution to it is not Index Lifecycle Management. Instead, it should be using date math index.

I am trying this out, and using Winlogbeat as a Beats example.

I would like to ask if it is just the simple step of adding these 3 lines in my winlogbeat.yml configuration file?

Line #1:
setup.template.name: "winlogbeat-test"

Line #2:
setup.template.pattern: "winlogbeat-test-*"

Line #3:
output.elasticsearch.index: "winlogbeat-%{[agent.version]}-%{+yyyy.MM.dd}"

The documentation reference page which I looked at for this is found here.

(I have no need for a custom name, and I would like to have the agent's version as part of the index name.)

Is there a reason for not using ILM?

It was mentioned in the Elastic Discuss post that:

I agree with it (its reasoning appeared sound to me). Moreover, what ILM offers is an age-based rollover, which isn't what I am looking for.

Yep, but I am just looking for why you want date based indices?

Right. Thank you for the clarification - this might sound silly, but I would like to find out how many documents are held in an index each day and the size that a daily batch worth of document's holds.

That's not silly, makes total sense :slight_smile: It's a limitation of ILM.
FWIW I raised Show per day size stats for ILM indices · Issue #100009 · elastic/kibana · GitHub to see if we can do something here.

Basically if you want this via Beats, just disable the ILM portion of the config.

Just found out that interestingly someone else raised the same underlying question just very recently!

Thank you so much for this. :slight_smile:
