Figure 55: MBean - attribute table
When you click an attribute in the table to select it, the details are displayed in the lower part of the window. This detailed view is intended for extensive attributes that cannot be displayed in full in the table.
The columns of the table have the following meanings:
Name / Description
Name and more detailed description of the attribute.
Type
Type of attribute value, e.g. string, integer, Boolean.
Value
Value of the attribute.
Exception
Specifies whether the JMX server delivered an exception when determining the value of the attribute If this is the case, you can display the exception in the attribute's detailed view.
Read
Specifies whether the attribute can be queried at the JMX server. This is the case for the majority of attributes.
Write
Specifies whether the attribute values can be modified.
Writable
Specifies whether the attribute value can be modified via the Management Console.
Only attributes with "simple" value types (string, integer, Boolean) can be modified via the Management Console. Attributes with complex (e.g. composite) values cannot usually be modified via the Management Console. These attributes are then identified as Write but not as Writable.
