1.5.2 JP1/IM system hierarchy
A system managed by JP1/IM consists of a manager (which performs integrated management of the system), agents (which run on the monitored servers), remotely monitored hosts, and a viewer (which is used for performing monitoring and operations).
To monitor a host as an agent, JP1/Base must be running on that host. A configuration where JP1/Base is running on the monitored hosts is called an agent configuration.
A configuration where remotely connected hosts are monitored is called a remote monitoring configuration. This configuration is supported by JP1/IM version 09-50 or later. You must set the hosts to be monitored for remote communication in advance. For details about communication settings, see 1.18 Settings for monitoring logs on remotely monitored hosts (for Windows) or 2.17 Settings for monitoring logs on remotely monitored hosts (for UNIX) in the Job Management Partner 1/Integrated Management - Manager Configuration Guide.
In an agent configuration, JP1/Base runs on each agent host. In a remote monitoring configuration, however, JP1/Base is not required on the remotely monitored hosts.
Agent configurations and remote monitoring configurations are collectively referred to as a system hierarchy or an IM configuration.
To centrally manage the system hierarchy (IM configuration) by using JP1/IM - Manager, you can use the IM Configuration Management functionality provided by JP1/IM - Manager to define the system hierarchy or to distribute the definition information of the system hierarchy (configuration definition information) to hosts.
Alternatively, you can define the system hierarchy using the configuration definition information in JP1/Base in the usual manner. Note that you cannot define the system hierarchy for the remotely monitored hosts in this manner.
In a JP1/IM system, managers can be arranged hierarchically to enable integrated management of systems whatever their size - from a small system serving a regional office to a large-scale system serving the entire enterprise. This allows you to add hosts to those being monitored, and makes it easy to migrate a small system to a large-scale hierarchical system.

In an agent configuration, you can configure a hierarchical system by placing base managers and relay managers under the integrated manager as shown in the above figure. To configure a hierarchical system, JP1/IM - Manager must be installed on the integrated manager host, base manager hosts, and relay manager host.
In a remote monitoring configuration, you cannot configure a hierarchical system. You must place remotely monitored hosts under the integrated manager or base managers.
The types of manager hosts configured in a JP1/IM system are as follows:
|
Type of manager host |
Description |
|---|---|
|
Integrated manager |
The integrated manager is at the top of the system hierarchy. It performs integrated management of base managers, relay managers, agents (excluding the agents under base managers), and remotely monitored hosts (excluding the remotely monitored hosts under base managers) in the system hierarchy. |
|
Base manager |
The base manager is placed between the integrated manager and agents or remotely monitored hosts when agents are managed at individual sites. The integrated manager manages base managers, and each base manager manages the agents and remotely monitored hosts that are placed under them. |
|
Relay manager |
Positioned at an intermediate level between the integrated manager and agents to collect events generated at the agent hosts. The relay manager and lower-level agents are managed by the integrated manager. Relay managers cannot be used in a remote monitoring configuration. |
Monitored hosts are classified into the following two types:
-
Agent
-
Remotely monitored host
