Cache Statistics

• Caches are used to store commonly accessed information so that they can be accessed at a smaller cost after the initial request.

• Caches are used throughout the framework to improve performance.

The following list defines every field available in the cache statistics (meta_v_c_cache_stat) table in alphabetical order:

• Current Cache Size - this field is not maintainable. The number of records currently stored in this cache.

• Hit Count - this field is not maintainable. The number of requests made to this cache where the requested record was already stored in the cache.

• Hit Rate - this field is not maintainable. The percentage of requests that were hits (where the record was already stored in the cache).
  • In a healthy cache, this percentage should be very high. A low percentage means that many of the requests were one-time hits, which would lower the usefulness of the cache.

• Maximum Cache Size - this field is not maintainable. The maximum number of elements that can be stored into the cache.

• Miss Count - this field is not maintainable. The number of requests made to the cache where the record was not in the cache and had to be retrieved.
  • This operation can be costly.

• Miss Rate - this field is not maintainable. The percentage of requests that were misses.
  • In a healthy cache, this percentage should be low.

• Request Count - this field is not maintainable. The number of requests made to this cache.

• Resource Name - this field is not maintainable. The resource name and description associated with a given cache. Value retrieved from the resources table
