I have a single EM and Collector instance, which collects from 100+ agents. A few of the agents have historical metrics that exploded a while back. I would like the cleanup to be limited to just those few agents, but I haven't found a way to do this. I opened a Support case ( 00526683 ) for the same, and the engineer also wasn't aware of any levers to do so. So he suggested I ask the question in the Community. Below is the documentation I used to educate myself on the possibilities, before I opened the case. If anyone has additional documentation and/or tips, I'd love to hear it! Thank you.
