Introduction

General Information

Computer Environment Operational Performance Management is an important topic, as data processing, memory and communication bottlenecks have much impact on the bottom line and production servers. This software is a server for data acquisition which enables Performance Monitor 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 monitoring. Features include:

Scan of multiple computers;

Intelligent scan load control;

Data filtering(averaging);

Compliant with the OPC DA2 specification;

Compatible with WMI Devices;

System Requirements

This OPC server has the following minimal 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 reachable computer running Windows with WMI enabled. The server core is heavily optimized to achieve high performance by measuring response times of every computer and balancing server load to maintain the specified refresh rate for all computers. It is possible to customize scan parameters from each computer. This feature allows you to build the most optimized configuration for your computer environment.

Tools Overview

XRatel Perfmon OPC/DDE Server provides three tools to manage servers and data and 2 servers to manage data acquisition. These tools are listed below:

XRatel Perfmon OPC/DDE Server - Server Configuration - This tool helps you to configure the PerfMon Server. It allows you to indicate which computers and tags should be monitored.

XRatel Perfmon OPC/DDE Server - Server Monitor - Allows you to manage PerfMon Server, simplifying server reboot, configuration reloading and displaying statistics about it.

XRatel Perfmon OPC/DDE Server - PerfMon Server - This is the software responsible by data acquisition and delivery. In OPC licenses, it acts as an OPC server.
