Grafana is free and open-source software. That visualizes and monitors data from sources such as Prometheus, InfluxDB, Graphite, and ElasticSearch. The built-in sharing feature is there in Grafana. Which allows you to share data.

A decent dashboard will appear in front of you.
Here, after successful installation, multiple things can be managed based upon your need. You can disable the signup option too.
Open file.
# nano /etc/grafana/grafana.ini
Search for the user section and mark allow sign up as false.
[users] # disable user signup / registration ;allow_sign_up = false # Allow non admin users to create organizations ;allow_org_create = true
