getClientStatistics

Map<String,String> getClientStatistics()

The statistics is a String that is composed of key=value pairs separated by ',' . The following characters are escaped in IMap and ICache names by the escape character '\' : '=' '.' ',' '\' The statistics key identify the category and name of the statistics. It is formatted as: mainCategory.subCategory.statisticName An e.g. Operating system committedVirtualMemorySize path would be: os.committedVirtualMemorySize The statistics key names can be one of the following (Used IMap named and ICache Named and assuming that the Near Cache is configured): clientType clusterConnectionTimestamp credentials.principal clientAddress clientName enterprise lastStatisticsCollectionTime nearcache..creationTime nearcache..evictions nearcache..expirations nearcache..hits nearcache..lastPersistenceDuration nearcache..lastPersistenceFailure nearcache..lastPersistenceKeyCount nearcache..lastPersistenceTime nearcache..lastPersistenceWrittenBytes nearcache..misses nearcache..ownedEntryCount nearcache..ownedEntryMemoryCost nearcache.hz/.creationTime nearcache.hz/.evictions nearcache.hz/.expirations nearcache.hz/.hits nearcache.hz/.lastPersistenceDuration nearcache.hz/.lastPersistenceFailure nearcache.hz/.lastPersistenceKeyCount nearcache.hz/.lastPersistenceTime nearcache.hz/.lastPersistenceWrittenBytes nearcache.hz/.misses nearcache.hz/.ownedEntryCount nearcache.hz/.ownedEntryMemoryCost os.committedVirtualMemorySize os.freePhysicalMemorySize os.freeSwapSpaceSize os.maxFileDescriptorCount os.openFileDescriptorCount os.processCpuTime os.systemLoadAverage os.totalPhysicalMemorySize os.totalSwapSpaceSize runtime.availableProcessors runtime.freeMemory runtime.maxMemory runtime.totalMemory runtime.uptime runtime.usedMemory userExecutor.queueSize Not: Please observe that the name for the ICache appears to be the hazelcast instance name "hz" followed by "/" and followed by the cache name provided which is StatTestCacheName.
