Real Test Case General

Test Information

This is a real test case using the server to monitor some SNMP devices over a slow network.

In a typical network environment there are equipments from many vendors and consequently different implementations of SNMP protocol which may interfere in performance, plus not all devices supports SNMPv2 which is known to be a faster implementation than SNMPv1.

Tested Network Environment

Server Computer Configuration:

AMD Sempron(tm) Processor 2800+

512MB DDR System Memory

40GB Disk space

100Mbps Network Connection

Running Microsoft Windows X with Service Pack 2

Monitored SNMP Devices:

50 Computers using Microsoft SNMP Service

Monitored Items: 816

SNMP Version: V1

Refresh Rate: 1000ms

Group Reads: 50 items per scan

Test Results

In this Real Test Case, the described system configuration was monitored during a half hour of operation and the following resources were monitored during this time.

XRatel SNMP OPC/DDE Server Server Processor Usage

Processor usage was monitored on every second and the average processor load was 9%.

real_cpu

Server Processor Usage

XRatel SNMP OPC/DDE Server Server Memory Usage

Memory usage was monitored on every second and the average memory use was 7MB.

real_memory

Server Memory Usage

XRatel SNMP OPC/DDE Server Server Network Usage

Network usage was monitored on every second and the average network use was 37KB for data in both directions.

real_network

Server Network Usage

XRatel SNMP OPC/DDE Server server sucessfully monitored 816 SNMP items every second in 50 devices with low resource usage. This situation can be easily reproduced by tuning the server profile and scanning only useful items.
