Add approximate size metrics

    XMLWordPrintable

Details

    Description

      Version 13.0 disabled the exact size metrics (local+clustered+container NumberOfEntries+NumberOfEntriesInMemory) in the default configuration (accurate-size="false". We need replacements that are not cheap(er) to compute, so they can be enabled in the default configuration.

      A first stab at the names is
      approximateEntries – number of entries in the cache
      approximateInMemoryEntries – number of entries in memory
      approximateUniqueEntries – number of unique entries in a clustered cache

      approximateEntries and approximateInMemoryEntries make sense both in the local stats and in the clustered stats (possibly counting each entry numOwners times).
      approximateUniqueEntries only makes sense in the clustered stats.

          Bug - A problem that impairs or prevents the functions of the product. ISPN-13728 Metrics incorrect, always showing -1 for current values.

          • Minor - To be worked after urgent, high, and medium priorities are resolved. This term is chosen when the severity of the issue is low, or the complexity or effort to correct it may be higher, relatively speaking. For low priority issues, known workarounds exist or are not needed due to the trivial effort needed to address the issue.
