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.

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.

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.

Keep Misses (%)
This metric reports the percentage of read requests to keep objects which did not find all data in Flash Cache since the last metric collection. In general, a low number of read misses indicates better performance. However, in cases where it is not beneficial to put data objects of a large size into flash cache, a high number of read misses does not necessarily indicate performance issues.
