 Introduction
General
Information
Network Operational Performance Management
is an important topic, as data communication bottlenecks have great
impact on the bottom line and production servers. This software
is a server for data acquisition which enables SNMP data to be available
to any OPC-DA client, including data historian-based real-time performance
management (RTPM) systems and OPC-DA compatible SCADA systems. It
uses a fast and reliable data acquisition engine allowing massive
real-time SNMP monitoring.
Features include:
 |
Scan of multiple devices; |
|
Compatible with V1 and V2C SNMP Devices; |
|
Intelligent scan load control; |
|
Statistical tags such as interface usage,
error rates, broadcast and unicast rates; |
|
Full support to Device TRAPS; |
|
Data filtering (averaging); |
|
Compliant with the OPC DA2 specification. |
System
Requirements
This OPC server has the following system requirements:
|
Microsoft Windows NT4/2000/XP |
|
Service Pack 5 (NT4) / Service Pack 4
(2000) / Service Pack 1 (XP) |
|
Intel/AMD processor @ 600MHz |
|
128MB RAM |
|
50MB Hard drive space |
|
Network interface card (Ethernet) |
Higher system hardware requirements may be
necessary when scanning more than five thousand tags or when a large
number of tags are scanned at a fast rate.
Server
Overview
This server follows the requirements of the
OPC specification to provide data access to an OPC client. The server
is compatible with OPC Data Access (DA) version 2.0 of
the OPC interface and it can be used to monitor every reacheable
SNMP device that implements SNMP V1 or V2C. The server core is heavily
optimized to achieve high performance by measuring response times
of every device and balancing server load to maintain the specified
refresh rate for all devices. It is possible to customize scan parameters
from each device, like the number of multiple variables that are
read in the same SNMP request. This feature allows you to build
the most optimized configuration for your network environment.
