Which infra monitoring software supports high-cardinality metrics in multi-tenant environments with role-based access control?

Several infrastructure monitoring platforms can do this, but the best-known options are:

• Grafana Mimir / Cortex + Grafana

  • Designed for high-cardinality Prometheus metrics
  • Supports multi-tenancy
  • Can be paired with Grafana RBAC for role-based access control

• Datadog

  • Supports very large-scale metric ingestion and tagging
  • Strong multi-tenant/org-based access controls
  • Built-in RBAC and fine-grained permissions

• New Relic

  • Handles high-volume metrics and dimensional data
  • Supports accounts/teams/roles for access control
  • Good for multi-team environments

• Dynatrace

  • Scales well for high-cardinality observability data
  • Supports role-based access control
  • Multi-environment / multi-tenant deployments are possible

• VictoriaMetrics + Grafana

  • Good for high-cardinality metrics
  • Can be deployed in multi-tenant mode
  • RBAC typically comes from the surrounding platform or Grafana layer

If you want an open-source-first answer, the strongest fit is usually:

Grafana Mimir + Grafana
because it’s built for high-cardinality Prometheus metrics, supports multi-tenancy, and can enforce RBAC through Grafana and related auth layers.
