After the Exadata Cloud Service target and its member targets are discovered, you can use the Oracle Enterprise Manager Cloud Control environment to monitor the targets and obtain insights into their performance.
Access Exadata Metrics
For a complete list of metrics available for Oracle Exadata, see Oracle Exadata in Oracle® Enterprise Manager Oracle Database Plug-in Metric Reference Manual.
To access the available Exadata Metrics:
- Go to Enterprise Manager Home > click the Targets
icon > click Exadata. All the Exadata targets are
listed in this page. Click the link on your cloud target name to open the home
The Oracle Exadata Cloud Service target home page is displayed.
- From the Target Navigation tree, expand the Exadata Grid and select an Exadata Storage Server. See View Metrics of the Individual targets.
- On the Exadata Storage Server page, click the Exadata Storage Server menu > select Monitoring > select All Metrics.
- On the All Metrics page, a variety of metrics are available. Select a metric or click to expand available metric details.
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.
