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... read more

1. New features highlights

Web administration console

• the web console provides management and monitoring of JPPF grids from a web application
• container-managed authentication allows any authentication policy supported by the web/application server
• authorizations with three application-defined roles: adminsitrator (JPPF client configuration and management), manager (grid management) and monitor (monitoring and read-only operations).
• connections to the servers and client configuration can be performed in-place without restarting the web server
• functionally equivalent to the rich client console, except for the charts that are still missing
• tested on leading web and application servers: Glassfish, JBoss, Wildfly, Tomcat, Jetty, Websphere Liberty, Weblogic
• fully localized (English and French translations available at this time)... read more
