Geode Statistics List

This section describes the primary statistics gathered by Geode when statistics are enabled.

All statistics gathering requires the gemfire.properties statistic-sampling-enabled in gemfire.properties file to be true. Statistics that use time require the gemfire.properties enable-time-statistics to be true.

Performance statistics are collected for each Java application or cache server that connects to a cluster.

Cache Performance (CachePerfStats)

Statistics for the Geode cache. These can be used to determine the type and number of cache operations being performed and how much time they consume.

Regarding Geode cache transactions, transaction-related statistics are compiled and stored as properties in the CachePerfStats statistic resource. Because the transaction’s data scope is the cache, these statistics are collected on a per-cache basis.

The primary statistics are:

Statistic	Description
cacheListenerCallsCompleted	Total number of times a cache listener call has completed.
cacheListenerCallsInProgress	Current number of threads doing a cache listener call.
cacheListenerCallTime	Total time spent doing cache listener calls.
cacheWriterCallsCompleted	Total number of times a cache writer call has completed.
cacheWriterCallsInProgress	Current number of threads doing a cache writer call.
cacheWriterCallTime	Total time spent doing cache writer calls.
compressions	Total number of compression operations.
compressTime	Total time, in nanoseconds, spent compressing data.
conflatedEvents	The number of events that were conflated, and not delivered to event listeners or gateway senders on this member. Events are typically conflated because a later event was already applied to the cache, or because a concurrent event was ignored to ensure cache consistency. Note that some members may discard an update while other members apply the update, depending on the order in which each member receives the update. For this reason, the conflatedEvents statistic will differ for each Geode member. See Consistency for Region Updates.
creates	The total number of times an entry is added to this cache.
decompressions	Total number of decompression operations.
decompressTime	Total time, in nanoseconds, spent decompressing data.
destroys	The total number of times a cache object entry has been destroyed in this cache.
diskTasksWaiting	The current number of disk tasks, such as oplog compactions and asynchronous recoveries, that are waiting for a thread to run the operation.

loadsInProgress	Current number of threads in this cache doing a cache load.
loadTime	Total time spent invoking loaders on this cache.
misses	Total number of times a get on the cache did not find a value already in local memory. The number of hits (that is, gets that did not miss) can be calculated by subtracting misses from gets.

preCompressedBytes	Total number of bytes before compressing.
previouslySeenEvents	The number of previously seen events ignored by the event tracker.
putAlls	The total number of times a map is added or replaced in this cache as a result of a local operation. Note, this only counts putAlls done explicitly on this cache; it does not count updates pushed from other caches.
putallTime	Total time spent replacing a map in this cache as a result of a local operation. This includes synchronizing on the map, invoking cache callbacks, sending messages to other caches and waiting for responses (if required).
puts	The total number of times an entry is added or replaced in this cache as a result of a local operation (put(), create(), or get() which results in load, netsearch, or netloading a value). Note, this only counts puts done explicitly on this cache; it does not count updates pushed from other caches.
putTime	Total time spent adding or replacing an entry in this cache as a result of a local operation. This includes synchronizing on the map, invoking cache callbacks, sending messages to other caches, and waiting for responses (if required).
queryExecutions	Total number of times some query has been executed.

Statistic	Description
asyncDistributionTimeoutExceeded	Incremented every time an asyncSocketWrite has exceeded async-distribution-timeout and an async queue has been created.

A healthy partitioned region maintains a value of zero. Add one or more data stores if the value remains above zero. High availability may cause brief fluctuations, but it should return to zero if sufficient data stores are present (for example, terminating one data store causes its data to fail over to another).

Statistic	Description
eventsConflated	Number of events conflated. If this is high, the server's dispatcher may be running slowly. This could be caused by one or more slow client.s causing blocking in their subscription queues.
eventsExpired	Number of events that have expired while in the subscription queue. If this is high on a secondary server, it might be that the MessageSyncInterval on the primary is set too high, causing the secondary to fall behind in event cleanup.
eventsQueued	Number of events placed in the subscription queue.
eventsRemoved	Number of events removed from the subscription queue.
eventsRemovedByQrm	Number of events removed based on a message sent from the primary. Only incremented while the subscription queue is in a secondary server.
eventsTaken	Number of events taken from the subscription queue.
numSequenceViolated	Number of events that had sequence ID less than or equal to the last sequence ID. The system assumes these events are duplicates and does not add them to the subscription queue. A non-zero value may indicate message loss.
numVoidRemovals	Number of events which were supposed to be destroyed from the subscription queue through remove but were removed by some other operation like conflation or expiration.
threadIdentifiers	Number of ThreadIdentifier objects (units) in the subscription queue.
