Advanced subnode configuration
Use advanced subnode configuration to override an agent configuration property in a subnode.
There is an option in IBM Tivoli Monitoring V6.2.1 and later agents that you can enable to override properties from any agent-level configuration section in a subnode instance. On the Subnode Configuration Overrides page, there is a check box labeled Allow any configuration property to be overridden in any subnode. See (Subnode configuration overrides). For this option to be enabled, select 6.2.1 as the Minimum ITM version when you name your agent (Naming your agent). If you choose this option, each subnode instance can override any property from any agent-level configuration section. But this property can be overridden only from the GUI and not from the itmcmd command line.
Procedure
The Allow any configuration property to be overridden in any subnode option causes an Advanced field that contains a list to be displayed on each subnode configuration panel (Figure 1). The initial selection in the Advanced field provides the brief directions: Select a section to override values.
Figure 1. Override configuration lists
- When you click the list, you see a list of all the non-subnode sections that contain configuration properties (Figure 2).
Figure 2. Sections to override
- Select a section. The properties from that section are temporarily added to the subnode panel. The value of any property that you change is added to the set of properties that are defined for the subnode. A data source in the subnode looks for property values in the subnode before it looks in the agent-level sections. See (Figure 3).
Figure 3. SNMP Version 1 Properties expanded
The following further information applies to overriding properties from agent-level sections:
- Properties that were copied to the subnode section are not shown when the agent-level section is selected in the Advanced list. For example, in (Figure 3), SNMP host is not displayed after the Advanced list because it was copied to the subnode properties and is already displayed.
- Sections that contain no properties to override do not have a selection in the Advanced list.
- Overridden values that you enter for one section are retained even if you select a different section to display different properties.
- Select Allow any configuration property to be overridden in any subnode to enable this feature in your agent. The minimum IBM Tivoli Monitoring version of the agent must be 6.2.1 or later. If it is set to 6.2, it is changed to 6.2.1, although you are prompted before the change is made. If you do not want to change the minimum version, you can cancel the setting at the prompt. If you set the minimum IBM Tivoli Monitoring version to 6.2.1, you cannot install on a version earlier than 6.2.1. (Figure 3).
