Grafana Enterprise Metrics 1.5 introduces significant updates aimed at improving multi-tenancy and query management for observability teams. Key enhancements include per-tenant usage metrics, allowing operators to monitor system usage at a granular level to manage resources and costs effectively. These metrics are collected via telemetry and displayed on pre-built dashboards that facilitate easy monitoring of each tenant's activity relative to set limits. Furthermore, the release simplifies querying across multiple tenants by introducing a wildcard character, which streamlines the process of accessing data across various tenants without needing to specify each one individually. This feature enhances user experience by reducing the complexity of query formulation, although caution is advised to avoid overwhelming the system. These updates are designed to enhance the functionality and user-friendliness of GEM, especially for those offering Prometheus-as-a-service.
