Aggregated Exadata FlashDisk and HardDisk Metric Example
This metric category contains metrics that are aggregated over either the hard disks or flash disks in a cell. Selecting this metric from the All Metrics page generates a high-level summary, as shown below:
Expand the Aggregated Exadata FlashDisk and HardDisk Metric in the All Metrics page to show a variety of metric details, such as Average CellDisk Read Throughput, which gives an indication of the average number of bytes read from the cell disk, or Total CellDisk IO Load, which gives an indication of the total input/output load to the celldisk.
Exadata Cell Metric Example
This metric category contains the performance metrics collected at the cell level for each cell, such as CPU utilization and memory utilization. Selecting this metric from the All Metrics page generates a high-level summary, as shown below:
Expand the Exadata Cell Metric in the All Metrics page to show a variety of metric details, such as CPU Utilization, which provides information about the CPU utilization, or Disk I/O Objective, which provides the optimization objective which IORM is configured to achieve, for example, Low Latency or Balanced for OLTP-oriented databases, or High Throughput for data warehouses.
