Cluster Capacity

The Cluster Capacity dashboard in Ozone Recon provides a centralized view of storage utilization across your entire cluster. Moving from high-level physical capacity to individual DataNode diagnostics, it tracks usable space, logical data distribution, pre-allocated storage, and pending deletion lifecycles to help you monitor storage health and balance capacity effectively.

The Cluster Capacity page is organized from top to bottom, moving from broad cluster metrics to granular node details:

• Cluster summary: Provides overall physical storage capacity details for the Ozone cluster.
• Service summary: Displays logical storage usage and details how Ozone space is consumed.
• Pending deletion lifecycle: Tracks how pending deletions move across the Ozone Manager (OM), Storage Container Manager (SCM), and DataNodes.
• Datanode insights: Offers detailed metrics on individual DataNode storage distribution and performance.
