Which NetApp management tool generates reports on volume storage capacity trending information?

Virtual Storage Console integrates NetApp storage management into VMware vSphere and does not provide general-purpose volume capacity trending or reporting functionality.

OnCommand Unified Manager continuously collects performance and capacity metrics, stores them historically, and provides dashboards and reports specifically designed to show volume storage capacity trends over time. These trending reports help administrators forecast future storage requirements and identify volumes approaching capacity thresholds, which is a core feature of the product.

OnCommand System Manager is a web-based GUI for day-to-day cluster administration tasks such as creating and managing volumes, not for generating historical capacity trend reports.

OnCommand Workflow Automation automates and orchestrates storage provisioning workflows and is not a reporting or capacity trending tool.
