[Detailed description of the issue or question]
Multiple nodes can be created on one pm server, and they can be monitored through grafana.
However, all users who come into Grafana can check all nodes.
I want to make it possible for users who have entered Grafana to check only nodes approved for themselves.
In other words, it means that each user wants to restrict the authority to check monitoring data of a specific node.
Is there any way to do this?
