Metric Descriptions


Metric	Description
Cell ID	The Cell ID, provided by the hardware vendor.
Flashcache hit ratio	The ratio, within the total physical disk requests, of physical disks requests that were resolved from the Flashcache, thereby saving the need to carry out physical disk reads.
Flashcache I/O Errors	The number of IO errors that were encountered on the Flashcache
Flashcache Keep read request misses (Keep Objects)	The number of read IO requests for 'keep' objects that did not find all data in Flashcache and therefore had to perform physical read operations.
Flashcache Keep read requests (Total)	The number of read IO requests for 'keep' objects that were resolved from the Flashcache, thereby saving the need to carry out physical disk reads.
Flashcache read request misses (Total)	The total number of read IO requests that did not find all the requested data in the Flashcache, and therefore had to perform read from disks.
Flashcache read requests (Keep objects)	The number of read IO requests that were resolved from the Flashcache, thereby saving the need to carry out physical disk reads.
Flashcache usage (Keep objects)	The amount of space (number of megabytes) used for 'keep' objects on the Flashcache.
Flashcache usage (total)	The number of megabytes used on the Flashcache.
MB of Flashcache misses	The total amount of data (number of megabytes) read from disks because not all requested data was found in the Flashcache.
MB Pushed out of the Flashcache for Keep objects	The amount (megabytes) of data pushed out of the Flashcache because the space limit for storing 'keep' objects has been exceeded.
MB Pushed out of the Flashcache for Keep objects rate	The rate (megabytes/second) at which data was pushed out of the Flashcache because the space limit for storing 'keep' objects has been exceeded.
MB read from Flashcache	The total amount of data (number of megabytes) from the Flashcache during the specified time range.
MB written to Flashcache	The total amount of data (number of megabytes) written to the Flashcache during the specified time range.

Cell Model	The brand and model of the cell hardware, as provided by the vendor.
Cell Name	The Exadata cell name.
Cell Offload Efficiency	The cell's offload efficiency. Cell Offload Processing is a procedure used by the oracle database server to push query predicates (that limit data retrieved by the query using filters and join conditions) to the Exadata cell.
Cell Status	The Exadata cell status.
CPUs	The total number of CPU units on the cell.
Interconnects	The total number of network interconnection cards (NICs).
Kernel Version	The host kernel's software version.
