We have deployed Elastic Agent on 1000+ VM's, i see default ILM policy is being used "metrics" for all the indices created by the elastic agent.
Can we change the settings directly on the ILM policy "metrics" ??? our requirement is to hold data for 90 days and delete right after.
If i change the currently ILM policy, will it apply for all the current indices or do i have to expliclity run any command.
Any help will be highly appreciated.
