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 and 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 SNMP monitoring. Features include:

 

bullet Scan of multiple devices;

 

bullet Compatible with V1, V2C and V3 SNMP and WMI Devices;

 

bullet Intelligent scan load control;

 

bullet Statistical tags such as interface usage, error rates, broadcast and unicast rates;

 

bullet Full support to Device TRAPS;

 

bullet Data filtering (averaging);

 

bullet Compliant with the OPC DA2 specification;

 

bullet Historian Service;

 

 

System Requirements

 

This OPC server has the following minimal system requirements:

 

bullet Microsoft Windows NT4/2000/XP;

 

bullet Service Pack 5(NT4) / Service Pack 4(2000) / Service Pack 1(X);

 

bullet Intel/AMD processor @ 600MHz;

 

bullet 128MB RAM;

 

bullet 50MB Hard drive space;

 

bullet 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 SNMP device that implements SNMP V1, V2C and V3 or every  reachable computer running Windows with WMI enabled. For the SNMP, 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. And for the PerfMon, 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 network environment.

 

 

Tools Overview

 

XRatel SNMP and PerfMon provides, two tools to manage servers and data and two servers to manage data acquisition, each one. The others tool, Tag Explorer and Health Analyst, show the data. These tools are listed below:
 

bullet XRatel Server Configuration - This tool helps you to configure both SNMP Server and Historian Service. It allows you to indicate witch devices and tag should be monitored and historied.

 

bullet XRatel Server Monitor - Allows you to manage SNMP Server, simplifying server reboot, configuration reloading and displaying statistics about it.

 

bullet XRatel Tag Explorer - This software can take all data stored by Historian Service, plotting charts and displaying values and alarms.

 

bullet XRatel Health Analyst - This software can take some tags data and show four charts in the same window in the last 60 minutes, 24 hours, 7 days and 30 days.

 

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

 

bullet XRatel Historian Service - This service is responsible to take all data captured in SNMP Server and to store it for future view.
