To properly evaluate the data returned by the data collection, assign attributes to the returned values.
Attributes are defined using the following format:
<attributes> <attribute name="AttributeName1" counter="true" type="INTEGER"/> <attribute name="AttributeName2" counter="false" type="STRING"/> </attributes>
Table 20.3. Attribute Elements
|name||The name of the attribute defined in the AS clause of the query.|
|counter||Whether the attribute is a counter type.
|type||The attribute value type. Possible values are INTEGER, STRING or FLOAT.|
If an attribute type is incorrectly defined in the attribute
definition, such as INTEGER instead of STRING, it is not
possible to change the value in the
custom.xml after the agent has started.
This is because it is not possible for the agent to alter
attribute types after they are defined. Attempting to change
it in that manner results in an
InvalidValueForTypeException error. To
correct this, you must stop the agent, edit the type
definition, rename the attribute, and restart the agent.
