Experimental Features

New

• Added the ability to analyze log files where Partition Events Logging has been enabled for logs generated from Coherence versions 21.06 and above. You can access this feature by selecting the Analyze Unavailable Time in Logfile button in the Coherence tab of VisualVM Preferences.

Introduced in version 1.0.1

Care should be taken when using the thread dump across members as it may adversely impact a running clusters performance.

Known Issues

• When taking one or more thread dumps, if you want full deadlock analysis, you should set the following system property on your Coherence JVMS -Dcom.oracle.coherence.common.util.Threads.dumpLocks=FULL
