5.3.4 Generation types
When generating a monitoring tree automatically, you can select one of three generation types: Generate, Show Differences, or Add.

- Organization of this subsection
(1) Processing when you select "Generate" as the generation type
When you select Generate to create a monitoring tree, the information displayed in the Monitoring Tree (Editing) window is erased, and then the monitoring tree is redrawn according to the tree structure of the template you selected under Generation Tree in the Auto-generation - Select Configuration window. The existing monitoring tree is completely erased and the new, automatically generated monitoring tree is added. Use this processing to replace the existing system when a new system is installed.
(2) Processing when you select "Show Differences" as the generation type
When you select Show Differences to create a monitoring tree, the monitoring conditions set for the monitoring objects stored in the JP1/IM - Manager monitoring objects database are compared with the monitoring conditions in the definition information (monitoring objects) that was collected and collated during the generation processing. Monitoring objects found to have different monitoring conditions than recorded in the database, and all monitoring groups containing those objects up to the topmost level, are created as difference information under a monitoring group called NEW_OBJECT.
This processing allows you to update a monitoring tree when a system is reconfigured, by collecting only the changed parts of the definition information.
This new monitoring node generated as difference information can be placed in an existing monitoring tree as required.
The following figure shows the generation of a monitoring tree that shows differences.

- Monitoring objects in the existing portion of the figure:
-
AA' is created from the original monitoring object AA. BB, CC, and DD incorporate the auto-generated objects without change. EE is an object added by the user for monitoring purposes.
- Definition information collected and collated at difference generation:
-
This area of the figure shows the definition information collected at difference generation from the products running in the current system, organized into tree form. This information is held internally by JP1/IM - Manager. The generated tree structure depends on the selected template.
- Difference portion of the figure:
-
This node contains the monitoring objects AA and FF, which JP1/IM - Manager determined to be absent from the existing portion as a result of comparing the monitoring conditions of the objects in that portion with the monitoring conditions of the objects in the definition information collected and collated at difference generation. A, B, and E are also generated in this node because they are the higher-level monitoring groups containing AA or FF.
(3) Processing when you select "Add" as the generation type
When you select Add to create a monitoring tree, an additional monitoring tree is added to those in JP1/IM - Manager's monitoring objects database. The structure of the tree follows the template you selected under Generation Tree in the Auto-generation - Select Configuration window. The monitoring tree is added at the end of the existing monitoring trees. Use this processing to add monitoring trees when, for example, you add business systems.
