1.2.1 Overview of a basic configuration system
A system consists of managers for administering the system, agents that are monitored, and viewers for monitoring and operating the system. In this manual, a system consisting of the two levels shown in the figure below is defined as a basic configuration system. Each host in the figure has one NIC and only one IP address assigned.

In this example, the system administrator uses the JP1 user name jp1admin to log in to a manager called a management server (admin), where he or she can use a viewer to monitor the entire system. The management server admin manages events issued by agents of the sales department (hostA and hostB) and agents of the product planning department (host1 and host2).
For details on settings if a host in the system has multiple NICs or if multiple IP addresses are assigned to an NIC, see the description of the communication protocols of JP1/Base in the JP1/Base User's Guide.
To execute commands on monitored hosts, a JP1 user account must be mapped to an OS user account by user mapping. For details about the user mapping procedure, see 2.2 Settings for executing commands on monitored hosts from JP1/IM - View.
