The Portworx OCI monitor pod primarily monitors the health of Kubernetes nodes within the cluster. It collects telemetry data and status updates about node health, resource availability, and connectivity to ensure the Kubernetes environment hosting Portworx pods remains stable and reliable. This monitoring is vital to detect node failures, performance degradation, or resource bottlenecks early, enabling prompt remedial action. The OCI monitor acts as a specialized component interacting with the Kubernetes control plane and Portworx services to provide real-time node health insights. This role is distinct from installation facilitation or network policy management, focusing instead on operational observability. Official Portworx operator and observability documentation describe the OCI monitor’s function as critical for node health monitoring and overall cluster reliability within Kubernetes environments running Portworx storage【Pure Storage Portworx Observability Docs†source】.

The command pxctl list autopilotrules is used to list all Autopilot rule objects across namespaces within a Portworx cluster. Autopilot rules define automated policies for storage operations like scaling and volume migration. This CLI command queries the Portworx control plane to retrieve and display all configured Autopilot rules, regardless of the Kubernetes namespace they reside in. Using kubectl commands alone is insufficient because Autopilot rules are managed internally by Portworx and may not correspond directly to Kubernetes resources. Official Portworx CLI documentation confirms pxctl list autopilotrules as the primary command for comprehensive Autopilot rule enumeration, enabling administrators to audit and manage storage automation policies efficiently【Pure Storage Portworx Autopilot Guide†source】.

Skinny Snapshots are a space-efficient snapshot technique used by Portworx for replicated volumes (Repl 2 or 3) when storage capacity is limited and no external Object Store is configured. Unlike full snapshots that duplicate data blocks, skinny snapshots capture only the differences (deltas) since the last snapshot, minimizing space consumption. This method allows administrators to take frequent snapshots without significantly impacting storage availability. Skinny Snapshots are particularly useful for on-premises environments or clusters without access to cloud object storage, balancing snapshot granularity with resource constraints. Official Portworx snapshot documentation explains how skinny snapshots work internally, improving backup and recovery capabilities under tight storage conditions without requiring cloud integration【Pure Storage Portworx Snapshot Guide†source】.

A local snapshot in Portworx refers to a point-in-time of a volume’s data that is stored within the same storage cluster as the original volume. Local snapshots use efficient -on-write techniques to minimize storage overhead while preserving the volume state for backup, recovery, or rollback operations. Unlike cloud or remote snapshots, local snapshots do not require network transfer or object storage integration, enabling fast snapshot creation and restoration with low latency. They are ideal for short-term data protection, testing, or recovery scenarios where immediate access to snapshots is required. Portworx’s snapshot documentation describes local snapshots as the foundational snapshot type, essential for operational backups and data consistency within Kubernetes clusters using Portworx storage【Pure Storage Portworx Snapshot Guide†source】.
