7 Hardware Management and Monitoring Using MBeans

This chapter describes how Oracle Communications Service Broker Netra 6000 High Availability Manager (HA Manager) displays Netra hardware MBeans. See "Netra HA Manager MBean Hardware Reference" for a list of the MBeans and their attributes and operations.

About Hardware MBeans

HA Manager includes hardware MBeans that you use to manage and monitor hardware equipment. Each MBeans is associated with a specific hardware component.

The HA Manager organizes MBeans into a hierarchy as defined in the Common Information Model (CIM). You navigate through the hardware MBeans hierarchy using the Administration Console.

For more information about the CIM, see:

http://dmtf.org/standards/cim

You can perform the following actions by using hardware MBeans:

• View their hierarchy

• Set MBean attribute values

• Get an MBean attribute value

• Execute an MBean operation

See "Netra HA Manager MBean Hardware Reference" for a complete list of the HA Manager hardware MBeans.

Navigating the Hardware MBeans Hierarchy

To navigate through the hardware MBeans hierarchy:

1. Open the Administration Console.

2. In the System tab, click the Hardware MBeans tab.

   The Hardware MBeans appears. Table 7-1 describes the icons that represent the different types of nodes in the MBean tree.

   Table 7-1 Nodes Icons

   Icon	Node
   	CIM element
   	Hardware MBean
   	Hardware MBean attribute
   	Hardware MBean operation

   
   

3. Navigate to the MBean by clicking the plus sign on its left.

   The attributes and operations of the selected MBean appear.

4. Select the attribute you want to set or get, or the operation you want to invoke.

   One of the following appears in the right pane:

   • If you select an attribute, the field that displays the attribute value appears.

   • If you select an operation, the fields for entering parameters and displaying the return value appear.

Setting an Attribute

You can set the value of an attribute. Depending on the attribute, the type of the value can be either boolean or a string.

To set an attribute:

1. Navigate to the MBean whose attribute you want to set.

   See "Navigating the Hardware MBeans Hierarchy" for more information.

2. Select the attribute.

   One of the following appears in the configuration pane:

   • If the attribute is boolean, a check box appears.

   • If the attribute is a string or integer, a field appears.

3. Modify the value as required and click the Set button.

Getting an Attribute

When you select an attribute in the MBeans tree, and the value of this attribute is already set, the current value is displayed. However, while you are reviewing the attribute value, another user might change it. To verify that the displayed value is the most updated one, you can ask HA Manager to get the current value.

To get the value of an attribute:

1. Navigate to the MBean whose attribute you want to get.

   See "Navigating the Hardware MBeans Hierarchy" for more information.

2. Select the attribute.

   One of the following appears in the configuration pane:

   • If the attribute is boolean, a check box appears. The state of the check box represents the value of the attribute.

   • If the attribute is a string or integer, a field appears. The value stored in the field represents the value of the attribute.

3. To get the updated value, click the Get button.

   The updated value is displayed in the field.

Executing an Operation

To execute an operation:

1. Navigate to the MBean whose operation you want to execute.

   See "Navigating the Hardware MBeans Hierarchy" for more information.

2. Select the operation that you want to execute.

   The fields for entering parameters and displaying the return value appear.

3. In the parameter fields, provide information as required.

4. Click the Execute button.

   The return value is displayed in the Output field.
