Management Console as a JMX client

The Management Console also contains a JMX client which permits you to monitor a resource adapter. It is possible to configure multiple JMX clients.

A JMX client can either be assigned to a resource adapter or can be configured as a free JMX client. To assign it to a resource adapter, you define the JMX client using the Define MBean Client command in the resource adapter's context menu and then specify its properties in the dialog which then follows, see Setting up the JMX client in the Management Console .

A JMX client communicates with the JMX server. This runs on the application server and makes the data available via so-called MBeans. The JMX client is therefore also known as the MBean client. This allows you to monitor the following objects:

• Resource adapters

• Connection factories

• Inbound connections

• Message endpoints

The MBean client can read the data and attributes made available by the MBeans. It also has write access to certain attributes. The following monitoring functions are provided:

• Display MBeans attributes

  The attributes include, for example, the configuration properties or certain statistical values of the corresponding MBean.

• Read notifications output by the MBeans

  Notifications must first be subscribed to via the MBeans.

  Notifications are messages which the application server generates when certain events occur. Notifications are also generated by the resource adapter and by the application server components which supply the MBeans.

• Collect and display statistical values

  Attribute values can be collected at fixed intervals and output in statistical form. These include, for example, the number of active connections or the number of rolled back transactions.

• Run operations

  Operations are specific functions that are implemented by the MBeans and accessible via the interface; in the case of connection factories, these are, for example, the functions cleanupPool and resetStatisticValues.

You can use the administration facilities to set the monitoring functions you want to use for each MBean client (notifications, statistics etc.). For this to be possible, there must be a connection between the Management Console and the JMX server on the application server. You can also define favorites to permit simple access to frequently used MBeans.
