Dynamic cache MBean statistics

Access cache statistics with the MBean interface, using JACL

• Obtain the MBean identifier with the queryNames command, for example:

  $AdminControl queryNames type=DynaCache,*  // Returns a list of the available dynamic cache MBeans
  
  

  Select your dynamic cache MBean and run the following command:

  set mbean <dynamic_cache_mbean>
  

• Retrieve the names of the available cache statistics:

  $AdminControl invoke $mbean getCacheStatisticNames

• Retrieve the names of the available cache instances:

  $AdminControl invoke $mbean getCacheInstanceNames

• Retrieve all of the available cache statistics for the base cache instance:

  $AdminControl invoke $mbean getAllCacheStatistics

• Retrieve all of the available cache statistics for the named cache instance:

  $AdminControl invoke $mbean getAllCacheStatistics "services/cache/servletInstance_4"

• Retrieve cache statistics that are specified by the names array for the base cache instance:

  $AdminControl invoke $mbean getCacheStatistics {"DiskCacheSizeInMB ObjectsReadFromDisk4000K RemoteObjectMisses"}

• Retrieve cache statistics that are specified by the names array for the named cache instance:

  $AdminControl invoke $mbean getCacheStatistics {services/cache/servletInstance_4 "ExplicitInvalidationsLocal CacheHits"}

• Retrieve all the cache IDs in memory for the named cache instance that matches the specified regular expression:

  $AdminControl invoke $mbean getCacheIDsInMemory {services/cache/servletInstance_4 \S}

• Retrieve all cache IDs on disk for the named cache instance that matches the specified regular expression:

  $AdminControl invoke $mbean getCacheIDsOnDisk {services/cache/servletInstance_4 \S}

• Retrieves the CacheEntry, which holds metadata information for the cache ID:

  $AdminControl invoke $mbean getCacheEntry {services/cache/servletInstance_4 cache_id_1}

• Invalidates all cache entries that match the pattern-mapped cache IDs in the named cache instance and all cache entries dependent upon the matched entries in the instance:

  $AdminControl invoke $mbean invalidateCacheIDs {services/cache/servletInstance_4 cache_id_1 true}
