ObjectGrid provides a system management infrastructure with which you can monitor and administer static ObjectGrid topology deployment environments. The system management architecture is a three-tiered approach: a user client connects to the management gateway server, which makes an ObjectGrid client connection to an ObjectGrid cluster. The management gateway is not needed for dynamic ObjectGrid deployment topologies.
Figure 1. System management diagram
The management gateway client tier contains any program that uses Java Management Extensions (JMX) to connect to the management gateway server. Any third-party JMX console as well as a client program that uses MX4J application programming interfaces (APIs) are included. The ObjectGrid client tier consists of the management gateway server. The management gateway acts as a server for the management gateway client tier and as a client to a functioning ObjectGrid cluster in the server tier. Also, an ObjectGrid client program can call the same APIs that the management gateway server calls if the user does not want to use JMX. Finally, the server tier consists of an ObjectGrid cluster.
The management gateway contains a set of managed beans (MBeans) and uses JMX to administer and monitor the ObjectGrid environment and is implemented by the MX4J open source project. MX4J is shipped with ObjectGrid.
The ObjectGrid JMX and MBean administration model was created to take advantage of the various JMX consoles that are available for administering JMX environments. You can put together dashboards using the JMX console of your choice. Consoles can be attached to the MBeans running on the management gateway Java virtual machine (JVM) and dashboards can be assembled using these MBeans. Consoles offer graphical histories or charts of numerical and string values.
Two options are provided for running system management commands.
- Call any command through the client-server infrastructure that is currently in place with the ObjectGridAdministrator interface.
- Use JMX to call these same commands, with the ObjectGrid MBeans acting as a wrapper to the ObjectGridAdministrator interface.
