Class JEDiagnostics

java.lang.Object

com.sleepycat.je.jmx.JEMBean

com.sleepycat.je.jmx.JEDiagnostics

All Implemented Interfaces:

com.sleepycat.je.dbi.EnvironmentImpl.MBeanRegistrar, javax.management.DynamicMBean

public class JEDiagnostics
extends JEMBean
implements javax.management.DynamicMBean

JEDiagnostics is a debugging mbean for a non replicated JE Environment. This is intended as a locus of field support functionality. While it may be used by the application developer, the primary use case is for a support situation. Currently much of this functionality is also available through the standard java.util.logging MBean.

It is a concrete MBean created by registering a JE Environment as an MBean through setting the JEDiagnostics system property. It only works on an active JE Environment, and one Environment can only have one JEDiagnostics instance. There are two attributes and one operation:

Attributes:

• consoleHandlerLevel: which sets the console handler level.
• fileHandlerLevel: which sets the file handler level.

Operations:

• resetLoggingLevel: which sets the level for the current loggers in the LogManager.

We can use these attributes and operations to dynamically change the logging level for debugging purposes.
