+# contrib/GenericJMX.conf
+# -----------------------
+#
+# This is an example config file for the ‘GenericJMX’ plugin, a plugin written
+# in Java to receive values via the “Java Management Extensions” (JMX). The
+# plugin can be found in the
+#   bindings/java/org/collectd/java/
+# directory of the source distribution.
+#
+# This sample config defines a couple of <MBean /> blocks which query MBeans
+# provided by the JVM itself, i. e. which should be available for all Java
+# processes. The following MBean blocks are defined:
+#
+#   +-------------------+------------------------------------------------+
+#   ! Name              ! Description                                    !
+#   +-------------------+------------------------------------------------+
+#   ! classes           ! Number of classes being loaded.                !
+#   ! compilation       ! Time spent by the JVM compiling or optimizing. !
+#   ! garbage_collector ! Number of garbage collections and time spent.  !
+#   ! memory            ! Generic heap/nonheap memory usage.             !
+#   ! memory_pool       ! Memory usage by memory pool.                   !
