JP1 Version 12 JP1/Integrated Management 2 - Manager Overview and System Design Guide


13.7.7 System design for using the Central Scope

Consider the following points in regard to using the Central Scope.

Organization of this subsection

(1) Host information managed by JP1/IM - Manager (Central Scope)

JP1/IM - Manager (Central Scope) compares host names to determine the monitoring tree structure, or to change the status of monitoring objects, when a monitoring tree is generated automatically or when the status of a monitoring object is changed.

When comparing host names, JP1/IM - Manager (Central Scope) uses the JP1/Base jp1hosts information or jp1hosts2 information, the OS hosts file, and the DNS or NIS settings. Where there are discrepancies between the host names defined in these settings and those recognized by the products to be represented in an automatically generated tree, or by products that issue JP1 events, information might not be acquired correctly or the status of a monitoring object might not be changed correctly.

Examples:
  • The monitoring objects collected by the auto-generation function relating to the same host appear as monitoring objects of different hosts.

  • The status of a monitoring object fails to change because the name of the host it is monitoring differs from the name of the host that issued the JP1 event.

To avoid these sorts of problems, JP1/IM - Manager (Central Scope) can manage host information using a database of its own. You can preempt any problems by registering the host names recognized by other programs in the JP1/IM - Manager (Central Scope)-specific host information.

To utilize host information in JP1/IM - Manager, prepare a jcs_hosts file, and register the information in the host information database. In the jcs_hosts file, write the real host name, alias, and IP address of the hosts to be monitored in the Monitoring Tree window, using the same format as the OS hosts file. You can specify a maximum of eight host names for one IP address.

Make sure that you prepare the host information file and register the information in the host information database before you configure the monitoring object environment.

(a) Notes

  • If referencing of the host information is unsuccessful, JP1 event processing and monitoring tree auto-generation by JP1/IM - Manager (Central Scope) might take a long time.

    So that the information can be referenced, set the following host names in the host information database of JP1/IM - Manager (Central Scope), the JP1/Base jp1hosts information or jp1hosts2 information, the hosts file of the host running JP1/IM - Manager (Central Scope), and the DNS or NIS:

    1. Any host name set in the status change condition for a monitoring object as an individual attribute value in an individual condition for which Host name comparison is selected.

    2. Any host name included in the attribute values of a JP1 event monitored by JP1/IM that might be set as the event attribute specified in an individual condition for which Host name comparison is selected (as in 1 above).

    3. All host names defined in the JP1/IM configuration management.

    4. All host names included in the configuration information of a linked product set up to support auto-generation of monitoring trees.
