10 Oracle Exadata

This chapter provides information about the Oracle Exadata metrics.

For each metric, it provides the following information:

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:

Oracle Exadata Storage Server

The Oracle Exadata target monitors the software and hardware performance of an individual Oracle Exadata Storage Server in the database.

Aggregated Exadata Capacity

This metric category contains the aggregated metrics of the Exadata Capacity metric category and it collects every 60 minutes.

Disk Size (GB)

This metric gives an indication of the size of the status in GB.

Target Version	Collection Frequency
All Versions	Every 60 Minutes

Disk Type

This metric reports the metrics are for hard disk, flash disk, flash cache, and grid disk.

Target Version	Collection Frequency
All Versions	Every 60 Minutes

Allocated (%)

This metric gives an indication of the percentage allocation of the total number of bytes for the hard disk, flash disk, flash cache, and grid disk.

Target Version	Collection Frequency
All Versions	Every 60 Minutes

Aggregated Exadata CellDisk

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.

Average CellDisk IO Load

This metric gives an indication of the average input/output load to the cell disk.

Target Version	Collection Frequency
All Versions	Every 15 Minutes

Average CellDisk Read IOPS

This metric gives an indication of the average number of read input/output operations per second.

Target Version	Collection Frequency
All Versions	Every 15 Minutes

Average CellDisk Read Response Time

This metric gives an indication of the average read response time to the cell disk.

Target Version	Collection Frequency
All Versions	Every 15 Minutes

Average CellDisk Read Throughput

This metric gives an indication of the average number of bytes read from the cell disk.

Maximum CellDisk IO Load

This metric gives an indication of the maximum input/output load to the cell disk.

Target Version	Collection Frequency

Total CellDisk IO Load

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.
