  • Read Only: true
    The product edition this Member is running. Possible values are Standard Edition (SE), Enterprise Edition (EE), Grid Edition (GE).
  • Read Only: true
    The publisher packet utilization for this cluster node since the node socket was last reopened.

  • The minimum number of milliseconds that a packet will remain queued in the Publisher`s re-send queue before it is resent to the recipient(s) if the packet has not been acknowledged. Setting this value too low can overflow the network with unnecessary repetitions. Setting the value too high can increase the overall latency by delaying the re-sends of dropped packets. Additionally, change of this value may need to be accompanied by a change in SendAckDelay value.
  • Read Only: true
    A configured name that can be used to indicate the role of a Member to the application. While managed by Coherence, this property is used only by the application.
  • The minimum number of milliseconds between the queueing of an Ack packet and the sending of the same. This value should be not more then a half of the ResendDelay value.
  • Read Only: true
    The number of packets currently scheduled for delivery. This number includes both packets that are to be sent immediately and packets that have already been sent and awaiting for acknowledgment. Packets that do not receive an acknowledgment within ResendDelay interval will be automatically resent.

    The date/time value (in cluster time) that this Member joined the cluster.
  • The ratio of spans to trace when tracing is enabled.
  • The maximum total number of packets in the send and resend queues that forces the publisher to pause client threads. Zero means no limit.

  • Read Only: true
    The average number of milliseconds per get() invocation since the last time statistics were reset. This statistic is only tracked for caches that may incur expensive hits (for example the front of a near cache).
  • Read Only: true
    The average number of milliseconds per get() invocation that is a hit. This statistic is only tracked for caches that may incur expensive hits (for example the front of a near cache).
  • Read Only: true
    The average number of milliseconds per get() invocation that is a miss. This statistic is only tracked for caches that may incur expensive hits (for example the front of a near cache).
  • Read Only: true
    The average number of milliseconds per put() invocation since the cache statistics were last reset. This statistic is only tracked for caches that may incur expensive hits (for example the front of a near cache).
  • The BatchFactor attribute is used to calculate the `soft-ripe` time for write-behind queue entries. A queue entry is considered to be `ripe` for a write operation if it has been in the write-behind queue for no less than the QueueDelay interval. The `soft-ripe` time is the point in time prior to the actual `ripe` time after which an entry will be included in a batched asynchronous write operation to the CacheStore (along with all other `ripe` and `soft-ripe` entries). This attribute is only applicable if asynchronous writes are enabled (i.e. the value of the QueueDelay attribute is greater than zero) and the CacheStore implements the storeAll() method. The value of the element is expressed as a percentage of the QueueDelay interval. Valid values are doubles in the interval [0.0, 1.0].
  • Read Only: true
    The rough number of cache hits since the last time statistics were reset. A cache hit is a read operation invocation (i.e. get()) for which an entry exists in this map.
  • Read Only: true
    The total number of milliseconds (since the last time statistics were reset) for the get() operations for which an entry existed in this map. This statistic is only tracked for caches that may incur expensive hits (for example the front of a near cache).
  • Read Only: true
    The rough number of cache misses since the last time statistics were reset.
  • Read Only: true
    The total number of milliseconds ( since the last time statistics were reset) for the get() operations for which no entry existed in this map. This statistic is only tracked for caches that may incur expensive hits (for example the front of a near cache).
  • Read Only: true
    The number of `prune` operations since the last time statistics were reset. A prune operation occurs every time the cache reaches its high watermark.
  • Read Only: true
    The total number of milliseconds for the prune operations since the last time statistics were reset.
  • Read Only: true
    The cache store type for this cache. Possible values include NONE, READ-ONLY, WRITE-THROUGH, WRITE-BEHIND.
  • Read Only: true
    The cache description.
  • eventInterceptorInfo
    Read Only: true
    An array of statistics for events processed by event interceptors.
  • Read Only: true
    The total number of events dispatched by the StorageManager since the last time the statistics were reset.
  • Read Only: true
    The number of evictions from the backing map managed by this StorageManager caused by entries expiry or insert operations that would make the underlying backing map to reach its configured size limit. The eviction count is used to audit the cache size in a static system. Cache Size = Insert Count - Remove Count - Eviction count. Therefore the eviction count is not reset by the reset statistics method.
  • The time-to-live for cache entries in milliseconds. Value of zero indicates that the automatic expiry is disabled. Change of this attribute will not affect already-scheduled expiry of existing entries.
  • The limit of the cache size measured in units. The cache will prune itself automatically once it reaches its maximum unit level. This is often referred to as the `high water mark` of the cache.
  • Read Only: true
    The rough probability (0 <= p <="1)" that the next invocation will be a hit, based on statistics collected since last time were reset.< div>
  • indexInfo
    Read Only: true
    An array of information for each index applied to the portion of the partitioned cache managed by the StorageManager. Each element is a string value that includes a ValueExtractor description, ordered flag (true to indicate that the contents of the index are ordered; false otherwise), and cardinality (number of unique values indexed).
  • Read Only: true
    The total units used by all indices on the associated cache.
  • Read Only: true
    The number of inserts into the backing map managed by this StorageManager. In addition to standard inserts caused by put and invoke operations or synthetic inserts caused by get operations with read-through backing map topology, this counter is incremented when distribution transfers move resources `into` the underlying backing map and is decremented when distribution transfers move data `out`. The insert count is used to audit the cache size in a static system. Cache Size = Insert Count - Remove Count - Eviction count. Therefore the insert count is not reset by the reset statistics method.
  • Read Only: true
    The number of filter-based listeners currently registered with the StorageManager.
  • Read Only: true
    The number of key-based listeners currently registered with the StorageManager.

    The number of locks currently granted for the portion of the partitioned cache managed by the StorageManager.
  • Read Only: true
    The number of pending lock requests for the portion of the partitioned cache managed by the StorageManager.
  • The number of units to which the cache will shrink when it prunes. This is often referred to as a `low water mark` of the cache.

    A string representation of a query with the longest execution time exceeding the MaxQueryThresholdMillis since statistics were last reset.
  • Read Only: true
    The duration in milliseconds of the longest query execution since statistics were last reset.
  • A query execution threshold in milliseconds The longest query executing longer than this threshold will be reported by the MaxQueryDescription attribute.

    The ID of member to which the MBean belongs
  • Read Only: true
    The average duration in milliseconds per non-optimized query execution since the statistics were last reset.
  • Read Only: true
    The total number of queries that could not be resolved or were partially resolved against indexes since statistics were last reset.
  • Read Only: true
    The total execution time in milliseconds for queries that could not be resolved or were partially resolved against indexes since statistics were last reset.
  • Read Only: true
    The average duration in milliseconds per optimized query execution since the statistics were last reset.
  • Read Only: true
    The total number of queries that were fully resolved using indexes since statistics were last reset.
  • Read Only: true
    The total execution time in milliseconds for queries that were fully resolved using indexes since statistics were last reset.
  • Read Only: true
    Deprecated - use attribute CacheStoreType instead.
  • Read Only: true
    Total number of times a query had to be re-evaluated due to a concurrent update since statistics were last reset. This statistics provides a measure of an impact of concurrent updates on the query perfomance. If the total number of queries is Q and the number of contentions is C then the expected performance degradation factor should be no more than (Q + C)/Q.
  • The number of seconds that an entry added to a write-behind queue will sit in the queue before being stored via a CacheStore. Applicable only for WRITE-BEHIND persistence type.
  • Read Only: true
    The size of the write-behind queue size. Applicable only for WRITE-BEHIND persistence type.
  • The RefreshFactor attribute is used to calculate the `soft-expiration` time for cache entries. Soft-expiration is the point in time prior to the actual expiration after which any access request for an entry will schedule an asynchronous load request for the entry. This attribute is only applicable for a ReadWriteBackingMap which has an internal LocalCache with scheduled automatic expiration. The value of this element is expressed as a percentage of the internal LocalCache expiration interval. Valid values are doubles in the interval[0.0, 1.0]. If zero, refresh-ahead scheduling will be disabled.
  • Read Only: true
    The timestamp when this model was last retrieved from a corresponding node. For local servers it is the local time.
  • Read Only: true
    The number of removes from the backing map managed by this StorageManager caused by operations such as clear, remove or invoke. The remove count is used to audit the cache size in a static system. Cache Size = Insert Count - Remove Count - Eviction count. Therefore the remove count is not reset by the reset statistics method.
  • The maximum size of the write-behind queue for which failed CacheStore write operations are requeued. If zero, the write-behind requeueing will be disabled. Applicable only for WRITE-BEHIND persistence type.
  • The cache service name
  • Read Only: true
    The number of entries in the cache.
  • Read Only: true
    The average number of entries stored per CacheStore write operation. A call to the store() method is counted as a batch of one, whereas a call to the storeAll() method is counted as a batch of the passed Map size. The value of this attribute is -1 if the persistence type is NONE.
