I want to write monitoring data in ES. At present, there are 4 indicators, each indicator is 5 minutes granularity, every 5 minutes has more than 10,000 data, about 3 million data a day.
The requirements are:
1. How should ES be designed based on time index? Can I index at a granularity of 1 day, 7 days, 30 days?
2. The data granularity is 5 minutes, but when querying, I want to return according to different granularities. For example, querying for 1 day is 5 minutes granularity, querying for 7 days is hourly granularity, and querying for 30 days is granularity of days.
Thanks god.

Hey,
regarding different granularities. If you want to reduce your data, you can use [rollup](https://www.elastic.co/guide/en/elasticsearch/reference/7.5/rollup-overview.html). However if space is not an issue, you can also query your 5 minute granularity data and query the last 30 days in a per-day granularity.
regarding time based indices: Take a look at [index lifecycle management](https://www.elastic.co/guide/en/elasticsearch/reference/7.5/getting-started-index-lifecycle-management.html), especially to rollover, which allows you to rollover after time, size or number of documents.
hope this helps as a start.

OKļ¼thanks a lot, but a problem is my elasticsearch version is 5.6.3, so rollup can't use, can I use other method in this version?

yes, you need to upgrade in order to use any of those. you may want to take a look at [curator](https://www.elastic.co/guide/en/elasticsearch/client/curator/5.8/index.html) that also works with older versions as it is an external process.
