# CloudNativePG PostgreSQL cluster visibility

> Monitor CloudNativePG in Radar: PostgreSQL cluster phase, primary and replica node distribution, backup status, storage config, and failover health in one detail view.

[CloudNativePG](https://cloudnative-pg.io/) (CNPG) is the Kubernetes operator for PostgreSQL, covering the full lifecycle from bootstrapping to monitoring, with high availability, automated failover, and backup management.

### What Radar Shows

**Cluster Detail View:**

* Phase, instances ready/desired, primary instance, image version
* Instance node distribution (which K8s nodes run each PostgreSQL instance)
* Storage configuration: data size, storage class, WAL storage
* Backup configuration: destination, retention policy, last successful backup, recovery point
* Monitoring: PodMonitor integration, custom query ConfigMaps
* Replication settings (for replica clusters)
* PostgreSQL parameters
* Health detection (AlertBanner for degraded clusters, failover/switchover in progress)

**Backup Detail View:**

* Phase, backup method, duration, start/stop timestamps
* Cluster reference with clickable link
* Destination path and server name
* Recovery target
* Failure detection (AlertBanner with error message)

**ScheduledBackup Detail View:**

* Cron schedule, last/next schedule timestamps
* Suspension detection (AlertBanner when paused)
* Backup configuration: cluster reference, method, owner reference settings

**Pooler Detail View:**

* Type (read-write/read-only) with colored badge, pool mode
* Instances ready/desired
* Cluster reference with clickable link
* PgBouncer parameters
* Degraded state detection (AlertBanner when not all instances ready)

**Resource Browser:** Smart columns show status, instance counts (with degraded highlighting), primary instance, image tag, storage size, cluster reference, and schedule expressions.
