FIFOEntryCacheMonitorEntry (UnboundID LDAP SDK for Java 7.0.2)

java.lang.Object
- com.unboundid.ldap.sdk.unboundidds.monitors.MonitorEntry

All Implemented Interfaces:

@NotMutable
 @ThreadSafety(level=COMPLETELY_THREADSAFE)
public final class FIFOEntryCacheMonitorEntry
extends MonitorEntry
```
This class defines a monitor entry that provides information about the sate of a FIFO entry cache in the Directory Server.

NOTE: This class, and other classes within the com.unboundid.ldap.sdk.unboundidds package structure, are only supported for use against Ping Identity, UnboundID, and Nokia/Alcatel-Lucent 8661 server products. These classes provide support for proprietary functionality or for external specifications that are not considered stable or mature enough to be guaranteed to work in an interoperable way with other types of LDAP servers.

The information that may be available about the entry cache includes:
- The name assigned to the cache.
- The number of attempts (successful and total) and the hit ratio when trying to retrieve an entry from the cache.
- The maximum allowed size of the entry cache in entries and bytes.
- The number of entries currently held in the cache.
- The number of entries added to or updated in the cache.
- The number of times an entry was not added to the cache because it was already present.
- The number of times an entry was not added to the cache because it did not match filter criteria required for inclusion.
- The number of times an entry was not added to the cache because it was too small to be included.
- The number of times an entry was evicted because of memory pressure or to make room for new entries.
- Information about the current memory consumption of the cache and whether the cache is currently full.
The server will automatically present one monitor entry for every FIFO entry cache defined in the server. It is possible to have multiple caches enabled if desired (e.g., one specifically targeting large static groups, and another small cache to help improve write-after-read performance). FIFO entry cache monitor entries can be retrieved using the MonitorManager.getFIFOEntryCacheMonitorEntries(com.unboundid.ldap.sdk.LDAPConnection) method. These monitor entries provide specific methods for accessing information about the FIFO entry cache. Alternately, this information may be accessed using the generic API. See the MonitorManager class documentation for an example that demonstrates the use of the generic API for accessing monitor data.
