1.3 GFI Network Server Monitor components
GFI Network Server Monitor is a client/server application, based on a central monitoring service
able to run on Windows NT or higher. This application monitors servers and workstations in your
LAN, WAN or even outside your enterprise without the need of any other additional software.
This software architecture allows for high reliability and scalability to monitor both large and
small networks.
GFI Network Server Monitor consists of 3 main modules which are:-
» NSMUI.exe – Network Server Monitor configuration and user interface.
» NSMENGINE.exe – Network Server Monitor engine/service (multi-threading engine able to
run 24 checks at a time).
» NSMATTENDANT.exe – Service which controls web result monitoring, web server access,
etc.
1.3.1 Network Server Monitor Engine
The GFI Network Server Monitor Engine is a windows service that polls the servers in your
LAN/WAN for availability at specific time intervals. This is a multithreading service, allowing 24
simultaneous checks to take place at the same time.
GFI Network Server Monitor only makes use of the protocols and application layers
available in the Operating System for running its checks, thus no agent software
installation is required on the servers to be monitored.
1.3.2 Network Server Monitor configuration
The GFI Network Server Monitor configuration program is the user interface to the GFI Network
Server Monitor engine. Use this module to configure all settings required for GFI Network Server
