# CNCF Perses Native Analytics Architecture

## Why Perses over Standalone Grafana?

Traditional NAS appliances that provide telemetry either bundle a heavy standalone Grafana instance (which requires its own SQLite/PostgreSQL database, user accounts, and separate session cookies) or write rudimentary, un-configurable charts into their dashboard.

NaxOS takes a pioneering approach by integrating **Perses** (a Cloud Native Computing Foundation project):

1. **GitOps & Declarative Native**:
   - Perses dashboards and datasources are written in clean JSON/CUE manifests.
   - Dashboards are checked into `/var/lib/perses/projects/naxos/dashboards` as code.
2. **Embedded Direct Visualization**:
   - The NaxOS Web Dashboard communicates with the internal Perses metrics API.
   - Eliminates Grafana's multi-megabyte bundle overhead, auth barriers, and database schema migrations.
3. **Optimized for OpenZFS Metrics**:
   - Out-of-the-box panels monitor OpenZFS ARC hits, misses, ARC target sizing, IOPS, and disk latencies scraped from Prometheus and Node Exporter.
