Description
Resources associated with direct and mapped buffers are difficult to monitor. It would be highly desirable to augment the monitoring & management support in the platform to include support for monitoring direct and mapped buffers.
Comments
EVALUATION We have define java.nio.BufferPoolMXBean for exactly this purpose. This allows jconsole or any JMX tool to monitor the usage of both direct and mapped buffers.
