3.1.1 Network monitoring types

There are several ways to monitor the network by using JP1 network management products. This subsection describes how to perform operations based on the map windows and how to check the resources.

Note: By using NEM, you can monitor the resources of the network switch in the same way as monitoring of the resources of the server. For details, see the NEM manual.

Organization of this subsection

(1) Monitoring by using topology maps (NNMi)
(2) Resource monitoring (SSO)

(1) Monitoring by using topology maps (NNMi)

In NNMi, network configuration diagrams (topology maps) are automatically created based on the discovered network devices. For this reason, you can visually determine the status of the network immediately after starting operation.

From the topology map, you can distinguish, based on the shape of the icon, the type of the network device, such as a router or computer. In addition, based on the color of the icon, you can determine the status of the network device, such as whether a failure has occurred. You can view not only the Layer 3 topology of the network, but also the Layer 2 topology. This enables you to intuitively check the status when a failure occurs and to understand the affected range.

(2) Resource monitoring (SSO)

With SSO, you can collect information about user resources (resources that can be uniquely defined by a user) and system resources (performance information, statistics, and operational information) of network devices and various server products that support SNMP and the OS (Windows or Linux), and monitor those resources in real time. For example, you can monitor an incident that was issued when the CPU utilization exceeded 90%.

In addition to issuing an incident, you can also specify that an action is to be automatically executed.
