13.5 Considerations for the system hierarchy
Consider the hosts to be managed by JP1/IM and their hierarchical relationships.
In JP1/IM, the configuration management functionality is used to determine the range of the systems to be monitored by JP1/IM. You can also configure a hierarchy with base managers or relay managers arranged below the integrated manager, and agents placed below the base managers or relay managers. You can also place hosts in a remote monitoring configuration, for which remote communication is set, below the integrated manager or the base managers.
For example, as shown in the figure below, you can have a mixed agent and remote monitoring configuration. In this figure, the machines placed in the head office are used as the integrated manager and a remotely managed host, the main machine placed in each branch office is used as the base manager, and other machines placed in individual branch offices are used as agents.

Using IM Configuration Management, you can monitor the hosts by business groups or monitoring groups, by defining business groups or by defining monitoring groups in each business group. Determine whether to operate the system by defining business groups, and consider the system hierarchy (IM configuration). For details about business groups, see 7.4 Managing business groups.
Using the configuration management functions, you can define the configuration of the system to be managed by JP1/IM as configuration definition information. This allows you to perform the following tasks:
-
Forward JP1 events to higher-level hosts
-
Execute commands remotely from JP1/IM - View
-
Execute automated actions from JP1/IM
-
Collect and distribute definition information
When using IM Configuration Management, you define the system hierarchy through IM Configuration Management - View. If you are not using IM Configuration Management, you define the system hierarchy using the JP1/Base configuration management functionality.
For details about these functions, see the following references:
- When using IM Configuration Management:

-
Hierarchical configurations that can be set with IM Configuration Management
See 7.2.1 Hierarchical configurations managed by IM Configuration Management.
-
- When not using IM Configuration Management:
-
-
Hierarchical configurations that can be set with the JP1/Base configuration management functions

Assume if you use IM Configuration Management and the jbsrt_distrib command provided by JP1/Base at the same time when you change the management mode after beginning managing the system hierarchy. If you do so, inconsistencies might occur between the information actually applied to the system and the configuration definition information retained by hosts, and the system operation might be disordered.
Therefore, we do not recommend that you change the management mode after beginning management of the system hierarchy. Carefully consider which mode of hierarchy management you want to employ before you start using the system.
