Hi there, As I understand from this [GitHub post](https://github.com/elastic/elasticsearch/issues/47838) and this [Elastic Discuss post](https://discuss.elastic.co/t/ilm-rotate-on-midnight/196279) 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](https://www.elastic.co/guide/en/beats/winlogbeat/current/change-index-name.html). (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: > [@](#): > > The whole point of using rollover is to allow indices to roll over based on size and/or age, which goes against specifying a time. If you want your indices to roll over at a specific time then set your index names accordingly and do not use rollover. 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 🙂 It's a limitation of ILM. FWIW I raised [Show per day size stats for ILM indices · Issue #100009 · elastic/kibana · GitHub](https://github.com/elastic/kibana/issues/100009) to see if we can do something here. Basically if you want this via Beats, just disable the [ILM portion](https://www.elastic.co/guide/en/beats/metricbeat/current/ilm.html) of the config. ---

Just found out that interestingly someone else raised the same underlying question just very recently! Thank you so much for this. 🙂 ---
