1.2.2 Distributed configuration
To monitor a large-scale system consisting of 1,000 or more monitoring servers, employ a distributed configuration in which NNMi and SSO run on separate servers. The following figure shows an example of a distributed configuration.
In a distributed configuration, the system is configured with the following components:
-
Management manager
-
Monitoring manager
-
Monitoring server
-
Remote operation terminal
- Management manager
-
The server on which NNMi runs. This server manages monitoring events that are reported as incidents from SSO.
- Monitoring manager
-
The server on which SSO runs. This server collects and monitors the system resources information of monitoring servers, and monitors processes and services on the monitoring servers.
- Monitoring server
-
A server or network device on which ESA and APM run.
ESA is an SNMP agent that is required for the collection of system resource information. APM is required for monitoring of the operating status of processes and services.
- Remote operation terminal
-
A Windows machine that is required as a web browser execution environment for using the SSO console.
- Supplementary note
-
The basic configuration and distributed configuration can be combined by installing SSO on the management manager. The following figure shows an example of the combination of the basic configuration and distributed configuration.
