Description
Metric table
The metric table can include some or all of the following: target version, default collection frequency, default warning threshold, default critical threshold, and alert text.
It includes the metrics collected for the following target types:
The Oracle Exadata target monitors the software and hardware performance of an individual Oracle Exadata Storage Server in the database.
This metric category contains the aggregated metrics of the Exadata Capacity metric category and it collects every 60 minutes.
This metric gives an indication of the size of the status in GB.
| Target Version | Collection Frequency |
|---|---|
| All Versions | Every 60 Minutes |
This metric category contains the aggregated cell disk performance metrics. The metric values are aggregated over all the cell disks in a cell. They are mainly aggregated via averaging and totaling.
This metric gives an indication of the average input/output load to the cell disk.

This metric gives an indication of the total input/output load to the celldisk. The Total CellDisk IO load is the aggregated number of IO requests waiting to be serviced by the storage server disks at any given point in time. You can think of this as the length of the queue for I/O requests.
Because the type of requests can be either for small or large reads, there is not one number that would indicate a potential performance issue. Oracle cannot recommend a number as each customer environment is often unique. Monitor the value of the I/O load and a number that correlates with poor response time will be a good candidate for a metric threshold. An Exadata system is underutilized if the I/O load is less than 20.
