This chapter describes the configuration of JMX Manager environment.
JEUS can be specified to enable JMX client access to MBeans.
To configure the operations of a JMX Manager, the server to which the JMX Manager is connected needs to be selected. Select the server from the WebAdmin main page. Or, click the [Servers] menu from the JEUS node tree on the left section of the WebAdmin screen, and then select the server from the Servers List page.
To get to the Jmx Manager page, click the [JMX Manager] sub tab under the [Resource] tab.
The JMX Manager configuration page consists of the following three sections that provide access to the monitoring information for JEUS.
To activate the configurations of JMX connector and SNMP adaptor, check the checkbox next to their names. For more information about the settings of JMX connector and SNMP adaptor, refer to their relevant sections.
This section explains how to configure the basic settings of the JMX Manager. For the 'Html Adaptor Port' and 'MLet Url' settings to be applied, the server needs to be restarted.
-
The HTML adaptor is JMX's protocol adaptor that supports HTML.
The HTML adaptor port is used to access the adaptor through a web browser. If set to -1, the JMX Manager does not use the HTML protocol. Make sure not to use a port that is used by other services.
To verify that the HTML adaptor has been configured successfully, run the web browser and then access the server using the IP address of the server and the specified port number.
The following is the screen that shows that the HTML adaptor is running successfully.
Note
For more information on HTML adaptor, refer to http://java.sun.com/developer/technicalArticles/J2SE/jmx.html.
-
Sets the MLet URL to register with the MBean server. For the specified MLet URL to be applied, the server needs to be restarted.
Note
For more information on MLet, refer to http://docs.oracle.com/javaee/1.4/api/javax/management/loading/MLet.html.
The JMX connectors used by a Java Client to remotely access JMX MBeanServer is as follows:
JMXMP connector is used by default. The configuration can be changed using WebAdmin.
Specify a listener port used to access JMX. If not specified, the common port for JEUS is used as the listener port for the JMXMP connector.
In 'Listener Ref ', specify the reference name of the unified listener that the JMXMP connector will use.
Note
To apply the JMXMP connector settings, the server should be restarted. For more information on the listener settings, refer to JEUS Server Guide. "2.3.2. Listener Configuration"
To activate the configurations of RMI connector, check the checkbox next to its name.
When the JMXMP connector has also been configured, the JEUS system will use the JMXMP connector internally. In this case, the 'Ref Export Name,' reference export name of an RMI connector used as a JMX connector, should be specified. If this name is not set or the specified name is same as the JMXMP connector name that JEUS provides, an exception will occur.
The following page specifies RMI Connector using WebAdmin.
Note
To apply the RMI connector settings, the server needs to be restarted.
When the RMI connector setting is successfully enabled and the server is started, the following log message will appear.
The following log message is shown for when 'Export Name' is set to 'RMIConnector' and 'Rmi Connector Port' is set to 9999. IP address can be different depending on the machine where the server is running.
. . . [2012.06.27 15:03:57][2] [adminServer-1] [JMX-0132] The RMIConnector service url is service:jmx:rmi://127.0.0.1:9999/jndi/RMIConnector . . .
SNMP adaptor is an SNMP protocol adaptor provided by JMX. To activate the configurations of SNMP adaptor, check the checkbox next to its name.
The following page specifies SNMP adaptor using WebAdmin.
Note
For more information on SNMP and SNMP Adaptor, refer to JEUS SNMP Guide. "Chapter 2. SNMP Agent".
