What are the minimum rights needed for letting users add their own metricbeat instance connected to a central elasticsearch cluster?
- user X installs metricbeat as a service with a given username and password on their machine
- it creates a custom prefix for an metricbeat-X- for that particular user so that an index per user is generated
What is the best way to set this up? So, what rights do I need to give that user to only write in those indices the users belongsto with the general Infrastructure UI in mind of Kibana.
