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, V2C and V3 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.
Historian Service.

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.

Tools Overview

XR SNMP Tools provides three tools to manage servers and data and 2 servers to manage data aquisition. These tools are listed below:

XR SNMP Tools Server FrontEnd - This tool helps you to configure both SNMP Server and Historian Service. It allows you to indicate wich devices and tag should be monitored and historied.
XR SNMP Tools Server Monitor - Allows you to manage SNMP Server, simplifying server reboot, configuration reloading and displaying statistics about it.
XR SNMP Tools Tag Explorer - This software can take all data stored by Historian Service, plotting charts and displaying values and alarms.
XR SNMP Tools SNMP Server - This is the software responsible by data acquisition and delivery. In OPC licenses, it acts as an OPC server.
XR SNMP Tools Historian Service - This service is responsible to take all data captured in SNMP Server and to store it for future view.
