JPPF makes it easy to parallelize computationally intensive tasks and execute them on a Grid

JPPF 6.0 alpha 4 new features highlights
----------------------------------------


Pluggable monitoring data providers
-----------------------------------

- this extension mechanism allows the management and monitoring API to provide user-defined data fields
  representing diagnostics data, health or general information on the JPPF node and driver JVM processes
  or the system on which they run
- custom data fields are automatically added to the JVM health view of the desktop and web administration consoles
- all numeric data fields are automatically made available to the user-defined charts of the desktop console
- monitoring data providers have full localization support
- the default data fields in the JVM health view are supplied by a built-in monitoring data provider

Documentation: https://www.jppf.org/doc/6.0/index.php?title=Monitoring_data_providers


New JVM / Process / System Health built-in data fields
------------------------------------------------------

Thanks to the integration of Oshi (https://github.com/oshi/oshi), new fields have been added that are not natively
available to the JVM:

- CPU temperature
- OS name and version
- Process Resident Set Size (RSS), how much memory is allocated to the process, excluding swap
- Process Virtual Memory Size (VSZ), shows all the memory the process can access, including swap
- Swap usage amount and percentage


Nio-based JMX remote connector
------------------------------

- full-fledged, fast and scalable, NIO-based implementation of the JMX remote specification
- available as a standalone JMX remote connector
- also fully integrated with JPPF, removing the need for JPPF servers to configure a separate JMX port
- now integrated as the default JMX remote connector in JPPF grids

Documentation: https://github.com/lolocohen/JPPF/tree/master/jmxremote-nio


Various enhancements
--------------------

- parametrized configuration properties
- port of the J2EE connector to Open Liberty 
  deployment doc: https://www.jppf.org/doc/6.0/index.php?title=Deployment_on_Open_Liberty
- pick lists are now used in the desktop console to select the visible columns of all tree views
