I have an ELK cluster with a fleetServer and some elasticAgents. As for now, I've added 2 prometheus integration to scrape the metrics from 2 different applications:

- The namespace of both prometheus package\_polices is: XXX
- The data\_stream.dataset for the prometheus package\_policy that scrapes the metrics for the application A is "prometheus.collector.appa"
- The data\_stream.dataset for the prometheus package\_policy that scrapes the metrics for the application B is "prometheus.collector.appb"

I can see the metrics in the following data streams:

- metrics-prometheus.collector.appa
- metrics-prometheus.collector.appb

The question is: I need to have a different ILM policy for appa and appb (the default metrics policy is not good for us). How can I define those ilm policies and assign it to the 2 different datastreams?

I tried this: [Tutorial: Customize built-in ILM policies | Elasticsearch Guide [8.15] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/example-using-index-lifecycle-policy.html) but it dind't help (unless I did something wrong)

Thank you
