# CNCF Perses Native Analytics Architecture
# Integrated Real-Time Telemetry & Metrics Architecture
## Why Perses over Standalone Grafana?
## Seamless In-App Telemetry vs. 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.
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 isolate graphs into a disconnected, foreign tab.

NaxOS takes a pioneering approach by integrating **Perses** (a Cloud Native Computing Foundation project) as the underlying declarative telemetry engine, weaving real-time metrics directly into the core appliance dashboard and storage views:
1. **GitOps & Declarative Native**:
- Perses dashboards and datasources are written in clean JSON/CUE manifests.
- Perses dashboards and datasources are written in clean declarative 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.
- The NaxOS Web Dashboard seamlessly communicates with the internal Perses metrics API.
- Eliminates Grafana's multi-megabyte bundle overhead, auth barriers, and database schema migrations.
- Telemetry widgets live naturally alongside storage pool management, active workloads, and system status.
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.
