 All Superinterfaces:

public interface LocalMapStats
extends com.hazelcast.instance.LocalInstanceStats
Local map statistics to be used by
MemberState
implementations.
As IMap
is a partitioned data structure in
Hazelcast, each member owns a fraction of the total number of entries of a
distributed map.
Depending on the IMap
's configuration, each
member may also hold backup entries of other members. LocalMapStats
provides the count of owned and backup entries besides their size in memory.

Method Details

getOwnedEntryCount
long getOwnedEntryCount()Returns the number of entries owned by this member. Returns:
 number of entries owned by this member.

getBackupEntryCount
long getBackupEntryCount()Returns the number of backup entries hold by this member. Returns:
 number of backup entries hold by this member.

getBackupCount
int getBackupCount()Returns the number of backups per entry. Returns:
 the number of backups per entry.

getOwnedEntryMemoryCost
long getOwnedEntryMemoryCost()Returns memory cost (number of bytes) of owned entries in this member. Returns:
 memory cost (number of bytes) of owned entries in this member.

getBackupEntryMemoryCost
long getBackupEntryMemoryCost()Returns memory cost (number of bytes) of backup entries in this member. Returns:
 memory cost (number of bytes) of backup entries in this member.

getCreationTime
long getCreationTime()Returns the creation time of this map on this member. Specified by:
getCreationTime
in interfacecom.hazelcast.instance.LocalInstanceStats
 Returns:
 creation time of this map on this member.

getLastAccessTime
long getLastAccessTime()Returns the last access (read) time of the locally owned entries. Returns:
 last access (read) time of the locally owned entries.

getLastUpdateTime
long getLastUpdateTime()Returns the last update time of the locally owned entries. Returns:
 last update time of the locally owned entries.

getHits
long getHits()Returns the number of hits (reads) of locally owned entries, including those which are no longer in the map (for example, may have been evicted).The number of hits may be inaccurate after a partition is migrated to a new owner member.
 Returns:
 number of hits (reads) of the locally owned entries.

getEvictionCount
long getEvictionCount() Returns:
 number of evictions happened on locally owned entries, backups are not included.

getExpirationCount
long getExpirationCount() Returns:
 number of expirations happened on locally owned entries, backups are not included.

getLockedEntryCount
long getLockedEntryCount()Returns the number of currently locked keys. The returned count includes locks on keys whether or not they are present in the map, since it is allowed to lock on keys that are not present. Returns:
 number of locked entries.

getDirtyEntryCount
long getDirtyEntryCount()Returns the number of entries that the member owns and are dirty (updated but not persisted yet). dirty entry count is meaningful when there is a persistence defined. Returns:
 the number of dirty entries that the member owns

getTotalSetLatency
long getTotalSetLatency()Returns the total latency of set operations. To get the average latency, divide by the number of sets Returns:
 the total latency of set operations

getTotalGetLatency
long getTotalGetLatency()Returns the total latency of get operations. To get the average latency, divide by the number of gets Returns:
 the total latency of get operations

getTotalRemoveLatency
long getTotalRemoveLatency()Returns the total latency of remove operations. To get the average latency, divide by the number of gets Returns:
