To check Portworx-specific alerts on a healthy node, administrators use the command pxctl alerts show. This command displays current alerts raised by Portworx, including warnings and critical notifications about storage, nodes, and cluster health. Even if one node is down, alerts from the healthy nodes can provide insights into cluster-wide issues or the status of the affected node. While journalctl displays system and service logs and kubectl describe node shows Kubernetes node info, neither provides aggregated Portworx alert data. The Portworx observability documentation recommends using pxctl alerts show for focused monitoring and alert management, enabling administrators to respond effectively to operational events within the Portworx cluster【Pure Storage Portworx Monitoring Guide†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】.

Defragmentation in Portworx reorganizes storage blocks to reduce fragmentation caused by frequent write and delete operations. Scheduling defragmentation during low workload periods ensures minimal impact on application performance while improving storage efficiency and I/O throughput. This optimization leads to faster read/write operations and prolongs the lifespan of storage devices by minimizing random I/O. Portworx provides administrators the ability to define defragmentation windows and recurrence policies within cluster configurations to automate this process. The official Portworx documentation explains that carefully timed defragmentation is critical to maintaining optimal cluster performance without disrupting business-critical workloads, making it an essential part of ongoing cluster maintenance and operational health【Pure Storage Portworx Performance Guide†source】.
