Exadata Fleet Capacity

The Exadata Fleet Capacity dashboard shows individual Exadata capacity averaged over the last 31 days across the Exadata and Recovery Appliance fleet or filtered subset of the fleet, allowing comparison by system.


Exadata Fleet Capacity dashboard

The dashboard includes multiple sections that provide detailed insights into specific dimensions of fleet resource capacity like host utilization, storage utilization, I/O performance, CPU, memory, disk usage, and IOPS (input/output operations per second). Detailed descriptions for each section are provided below:

Database Server CPU and Memory

The Host Utilization bubble chart in this section visualizes the average utilization of CPU and memory across all hosts (database servers) in an Engineered Systems over the past month.


Database Server CPU and Memory

  • X-axis (Memory Utilization %): Represents the memory utilization percentage, ranging from 0% to 100%
  • Y-axis (CPU Utilization %): Represents the CPU utilization percentage, ranging from 0% to 100%
  • Bubbles: Each bubble corresponds to a different Engineered System.
    • The size of the bubble indicates the total CPU count of the database servers in an Engineered System, with larger bubbles representing Engineered Systems with a higher number of CPUs.
    • The color of the bubbles is determined by the Group By filter setting.
  • Tooltip: A tooltip provides detailed information for a specific Engineered System when hovered over. For example, the Database Machine target shown in the example above has a CPU utilization of 65.34%, memory utilization of 22.46%, and a CPU count of 336. The lifecycle status for this target is not set.

    In all the bubble charts, the tooltip displays the values for the target property as specified in the Group By filter. The bubble color is determined by the value of the specified target property.
