C.9.9. Oracle::Index Extents

The Oracle::Index Extents probe monitors an Oracle instance and collects the following metric:

• Available Extents — The percentage of available extents for any index.
The required Index Name field contains a default value of % that matches any index name.

C.9.10. Oracle::Library Cache

The Oracle::Library Cache probe computes the Library Cache Miss Ratio so as to optimize the
SHARED_POOL_SIZE in init.ora. It collects the following metrics:
• Library Cache Miss Ratio — The rate at which a library cache pin miss occurs. This happens when
a session executes a statement that it has already parsed but finds that the statement is no longer in
the shared pool.
• Executions — The number of times a pin was requested for objects of this namespace.
• Cache Misses — The number of pins of objects with previous pins since the object handle was
created that must now retrieve the object from disk.
