To enable Portworx metrics exposure compatible with external Prometheus servers, administrators must set the exportMetrics flag inside the Prometheus monitoring section of the StorageCluster spec. The correct configuration is:

spec:

monitoring:

prometheus:

exportMetrics: true

This declarative configuration directs Portworx to expose its internal metrics on Prometheus endpoints, allowing external monitoring tools to scrape these metrics for observability, alerting, and dashboarding. The operator-managed Portworx cluster leverages this configuration for integration with cloud-native monitoring stacks, ensuring seamless visibility into cluster health, performance, and resource utilization. Using CLI commands alone is insufficient for operator-managed clusters since they don't persist settings or integrate with Kubernetes manifests. The official Portworx observability guide and operator documentation endorse this method as the recommended approach for metrics exposure and integration with Prometheus-compatible systemsPure Storage Portworx Monitoring Guidesource.

Portworx primarily relies on Direct Attached Storage (DAS) for its storage provisioning. DAS refers to physical disks or SSDs directly connected to the nodes running Portworx. Using DAS enables high-performance, low-latency access to storage resources, crucial for stateful containerized applications. Portworx aggregates and abstracts these local devices into distributed storage pools, providing features like replication, encryption, and snapshots. While Portworx integrates with Object Storage for cloud snapshots and disaster recovery, and can support NFS for certain use cases, the core storage provisioning and volume management depend on DAS. The Portworx architecture documentation clarifies that leveraging local node storage is essential for delivering performant, resilient, and scalable persistent storage in Kubernetes environmentsPure Storage Portworx Architecture Guidesource.

In Portworx, managing credentials for cloud object stores is vital to enable features like cloud snapshots and backups. The command pxctl credentials create is used to create and register cloud credentials with the Portworx cluster. This command allows administrators to specify provider details such as AWS, Google Cloud, or Azure, and input necessary access keys, secret keys, regions, and endpoints. Proper credential configuration enables Portworx to authenticate with external object stores securely, ensuring reliable data movement and disaster recovery operations. The CLI facilitates easy credential management, including listing, updating, and deleting credentials as needed. Official Portworx documentation highlights pxctl credentials create as the authoritative command for establishing cloud storage access, ensuring security best practices by managing credentials centrally within the Portworx control planePure Storage Portworx CLI Guidesource.

The VolumeSnapshot Kubernetes resource provides metadata about snapshots of Persistent Volumes, including references to the parent volume and snapshot IDs. It represents a snapshot request and maintains information linking it to the source PVC and the actual snapshot data. This resource enables Kubernetes-native management of volume snapshots, allowing users to create, delete, and list snapshots declaratively. Portworx integrates with Kubernetes snapshot APIs and populates VolumeSnapshot resources with detailed information necessary for managing snapshot lifecycle and restoring data. The Kubernetes and Portworx documentation highlight VolumeSnapshot as the primary interface to monitor and interact with snapshot metadata, crucial for backup, restore, and disaster recovery workflows in containerized environmentsPure Storage Portworx Snapshot API Guidesource.

Stork version 2.3 is the minimum version required to support Application Backup features in Portworx. Application Backup allows for consistent snapshots and restores of complex, multi-volume, and multi-pod stateful applications. This capability depends on enhancements introduced in Stork 2.3 that enable application-aware backup orchestration, coordination between Kubernetes and storage layers, and integration with backup policies. Earlier Stork versions lack these features, making them unsuitable for application-level backups. Portworx release notes and Stork documentation confirm that version 2.3 introduced key functionalities that underpin the reliable backup and restore workflows for stateful workloads, making it a baseline requirement for disaster recovery and business continuity implementations involving application backupsPure Storage Portworx Backup Docssource.
