I'm trying to configure a prometheus server working with ansible. I want to monitor some aws instances (ec2) but I'm stuck with the targets of prometheus. I probably should use a json file to define my targets but I don't know how to update the file when I create a new instance with ansible. Also I'm using the aws_ec2 plugin for the dynamic inventory on ansible.
So my question is: how can I use the inventory plugin to keep update the target file of prometheus without doing it manually?
