The pxctl command-line interface is the primary tool for managing and monitoring Portworx clusters. It provides detailed health information, including node status, volume health, storage pools, and alerts. Running commands like pxctl status or pxctl cluster status offers real-time visibility into the cluster's operational state. While kubectl manages Kubernetes resources and helm handles package deployment, neither provides the specialized insight into Portworx storage internals that pxctl delivers. Portworx operational best practices emphasize using pxctl for health checks, troubleshooting, and maintenance tasks to ensure cluster reliability and performancePure Storage Portworx CLI Guidesource.

The Portworx diagnostics bundle, known as ''diags,'' aggregates comprehensive diagnostic data for troubleshooting. This includes Portworx journal logs, which record detailed system and service events essential for identifying errors or malfunctions. Additionally, the bundle contains outputs from key CLI commands such as pxctl status and pxctl volume list that provide snapshots of the cluster's health, volume states, and configuration at the time of collection. Basic operating system information, including kernel version, disk hardware details, and network interfaces, is also captured to understand the underlying environment. Together, these components equip Portworx support and administrators with the contextual data needed for effective root cause analysis and faster issue resolution. The official Portworx support documentation recommends collecting and submitting this bundle for all significant troubleshooting cases as it expedites problem diagnosis and resolutionPure Storage Portworx Support Guidesource.

When using shared authentication in Portworx, the Kubernetes secret that contains the authentication token or credentials is stored in the same namespace where the application requesting storage resides. This placement ensures that the application pods have access to the secret needed to authenticate to Portworx for volume provisioning and management. It enables a security boundary aligned with Kubernetes namespaces, restricting credentials to the scope of the application. Storing the secret in the default namespace or the Portworx installation namespace would be less secure or less flexible in multi-tenant clusters. Portworx authentication documentation highlights this design for efficient, secure access management in Kubernetes environmentsPure Storage Portworx Security Guidesource.

Portworx recommends using Prometheus, Alertmanager, and Grafana as the core technologies for monitoring Portworx clusters within Kubernetes. Prometheus scrapes metrics exposed by Portworx components and stores time-series data for analysis. Alertmanager handles alert rules and notification delivery, enabling administrators to respond to critical events promptly. Grafana provides a powerful visualization platform to build dashboards from Prometheus data, helping teams visualize cluster health, performance metrics, and capacity trends. This combination is widely adopted due to its native Kubernetes integration, scalability, and extensibility. Portworx documentation includes detailed guidance on configuring these tools to monitor metrics such as volume latency, node health, pool usage, and snapshot status, forming a comprehensive monitoring and alerting solution for production environmentsPure Storage Portworx Monitoring Guidesource.

After configuring credentials for AWS S3 object storage, the administrator uses the command pxctl cloudsnap backup <volumename> -cred-id <credentials-name> to create a cloud snapshot backup of a Portworx volume. This command instructs Portworx to take a point-in-time snapshot of the specified volume and upload it securely to the configured S3 bucket using the referenced credentials. The command leverages Portworx's cloud snapshot feature for disaster recovery and long-term retention. Option B relates to creating credentials and is not the backup command. Option C creates a local snapshot but does not back it up to the cloud. The Portworx CLI documentation highlights pxctl cloudsnap backup as the core method to perform backups to cloud object storage, enabling data protection strategies aligned with cloud-native architecturesPure Storage Portworx Cloud Snapshot Guidesource.
