JP1 Version 12 JP1/SNMP System Observer Description, Operator's Guide and Reference

M. Glossary

automated action

A function that issues a command automatically on the monitoring manager or the agent when a status change is detected during the threshold monitoring by SSO for an application or resource.


A group of multiple resources. Resources provided by SSO belong to the SSO or SSO-Ex category. Resources that are defined by users belong to the USER category.

cluster system

A system that includes multiple server systems linked to each other appropriately. The purpose of clustering is to continue system operation when an error occurs. When an error occurs in the operating server (main system), the standby server (secondary system) will take over the system operation tasks. Since the secondary system switches to the main system, the cluster system is also referred to as a system-switching system.

The term cluster system also means a system provided with a load distribution feature based on parallel processing. In this manual, however, the term is used to indicate the system switching function that is useful for preventing system operation from being interrupted.

collecting server

A server that collects resources. A collecting server requires that SSO be installed.

collection condition

Condition for resource collection. It includes information on the resource to be collected, collection interval, collection duration, and collection mode (data storage and threshold).

collection database

A database that holds data representing collected resources.

dual stack

A capability of a host that has both of IPv4 and IPv6 addresses and can communicate with others by using either Internet protocol.

health check

A function used to verify that APM is normally active on a server and that the monitoring condition on SSO matches that on APM. The health check function is also used for other types of verification.


The entity of a resource value in terms of the resource collection by SSO.

For example, regarding the file system utilization in the file system group, each file system is an instance, and, regarding the CPU utilization in the CPU group, each CPU is an instance.


An acronym of Internet Protocol Version 4. IPv4 manages addresses as 32-bit data.


An acronym of Internet Protocol Version 6. IPv6 manages addresses as 128-bit data.


A program that collects and manages server resources in a network and monitors processes.

JP1/Cm2/SSO - Agent for Process

A program that monitors processes that run on a server.

logical host

A host that functions as a logical server in a JP1 environment for a cluster system. When an error occurs on the main system, the logical host that has served for the secondary system will be switched to the logical host for the main system.

A logical host is assigned its own IP address (logical IP address). When system switching takes place, the new main system will take over the IP address from the logical system that has served for the main system. When clients access the server, they can use the same IP address before and after the error occurs, as if only one server served for the clients.

logical IP address

The address that is specified as the IP address of a logical host included in a cluster system.

management manager

A machine that manages the monitoring events that are reported from SSO in a distributed system configuration. The management manager must have NNMi installed.

monitoring manager

A machine that monitors results of resource collection and process monitoring in a consistent manner. Any monitoring manager requires that SSO be installed.

In the basic system configuration, the monitoring manager is the machine on which SSO and NNMi are running. In a distributed system configuration, the monitoring manager is a machine on which SSO alone is running.

monitoring server

A machine that monitors processes. Any monitoring server requires that APM be installed.


A program used to manage the configuration, performance, and problems of a network. You can reference the incidents and events issued by SSO programs in the incident view and incident form of NNMi. NNMi is a prerequisite program for SSO.

performance data

Dynamic information, such as system operation information and statistical information. Performance data can be displayed in the Resource Browser window.

periodic inquiry

A function to periodically collect resources at specified intervals.

plot interval

A length of time that is specified in the plot_type key in the report definition file and in the Plot type field in the Report Type Setup window.

plot point

Plot points are used to draw a graph line in a graph to be output. The collected data is averaged at plot intervals, and calculated as coordinate values.

Regional Manager

A manager that sends event and other information to the global manager in an NNMi global network management environment.

remote command

A command that is issued automatically or at any timing from the monitoring manager to a monitoring server.


A group of multiple subresources. A collection condition can be specified for each resource.

resource directory

A directory that holds a collection database.

resource group

A group of multiple resources.

server targeted for collection

A server from which resources are to be collected. A server targeted for collection requires SNMP Agent installed.

SNMP agent

A program that manages system resources on a server. SSO manages resources based on information managed by SNMP Agent.

statistics information database

A database that is used internally to calculate thresholds when statistical thresholds are monitored.


A minimum unit of resource that can be acquired from SNMP Agent. Thresholds can be specified for each subresource.

summary data

Static information, including computer configuration and setting information. Summary data can be displayed in the Resource Browser window.

system-switching system

See Cluster system.


A value used to judge the status of a resource or process. For a resource, a threshold can be set for each subresource. For processes, a threshold indicates the number of processes that can be activated concurrently.


A technology that enables communication between different protocols by packet encapsulation and decapsulation.

variable binding(s) or VarBind

A list of pairs of an object identifier (that specifies the information attached to an SNMP trap) and a value.


A process the termination of which is not known to its parent process.
