[SNMP4J] snmp vs jmx

[Frank Fock]

As a small appetizer for the JMX API I provide an
example code to instrument the jvmClassesLoadedCount
MIB object of the JVM-MANAGEMENT-MIB with the new
API:

..
     JMXDefaultMOFactory jmxFactory = new JMXDefaultMOFactory(
       ManagementFactory.getPlatformMBeanServer());
     JvmManagementMib.moFactory = jmxFactory;
     MBeanAttributeMOScalarSupport scalarSupport =
         new MBeanAttributeMOScalarSupport(jmxFactory.getServer());
     jmxFactory.setScalarSupport(scalarSupport);
     try {
// The following code instruments a scalar with JMX:
       scalarSupport.add(JvmManagementMib.oidJvmClassesLoadedCount,
         new MBeanAttributeMOInfo(
		new ObjectName("java.lang:type=ClassLoading"),
                 "LoadedClassCount",
                 Integer.class));
// End of instrumentation
     } catch (Exception ex) { ex.printStackTrace(); }
..


Best regards,
Frank
