Prometheus Access Control Guide

User permissions management and access control in Prometheus can be achieved by following these steps:

1. Utilize an OAuth2-based authentication service: Prometheus itself does not offer user management and permission control functions, but can achieve user authentication by integrating an external OAuth2 authentication service. Common OAuth2 authentication services include Keycloak, Auth0, and others.
2. Utilizing Prometheus Alertmanager: Alertmanager, a component of Prometheus, can handle alerts and notifications. You can configure Alertmanager to manage access control for different users or user groups, as well as set various alerting rules.
3. Utilizing Prometheus’s TLS encryption feature ensures secure communication between the server and client, safeguarding data transmission and preventing unauthorized access.
4. By utilizing Prometheus’ RBAC feature, introduced in version 2.22.0, users can implement access control by configuring roles and permission rules.

By using the above methods, it is possible to manage user permissions and access control in Prometheus, ensuring the security and reliability of the system.
