Introduction
The Network Management System (NMS), and the DEFINITY Proxy Agent, along
with DEFINITY Performance Management, facilitate centralized management of
DEFINITY systems. To maintain this centralized management, Performance
Management complies with Simple Network Management Protocol (SNMP).
While the DEFINITY Proxy Agent is SNMP compliant, it operates remotely and
connects to multiple managed nodes concurrently.
SNMP
Information
Exchange
SNMP specifications define how Performance Management and DEFINITY
systems exchange information. The information exchange works like this:
1 Proxy Agents receives a call to request data.
2 Proxy Agents receive data from managed nodes.
3 Proxy Agents manage the information with a Management Information Base
(MIB).
4 Proxy Agents use SNMP protocol to translate the information into data that
the NMS can read.
5 Proxy Agents forward alert and threshold data to the NMS.
6 The NMS translates and displays the information on submaps that depict
DEFINITY systems.
